Are we alone in the universe?

EXTRATERRESTRIAL LIFE

Have you ever looked up at the night sky and wondered whether someone—or something—might be looking back at us? The universe is so enormous that Earth is only a tiny part of it. This raises one of the most fascinating questions in science: Are we the only living beings in the universe?

The term extraterrestrial life refers to any form of life that exists beyond Earth. Scientists have not yet found confirmed evidence of extraterrestrial life, but they continue to search for it.

A UNIVERSE FULL OF POSSIBILITIES 

The universe contains billions of galaxies, and each galaxy contains billions of stars. Many of these stars have planets orbiting them. Scientists have discovered thousands of planets outside our Solar System, known as exoplanets.

Some exoplanets orbit at a distance from their stars where temperatures could potentially allow liquid water to exist. This region is called the habitable zone or the “Goldilocks zone”—not too hot and not too cold.

Water is considered extremely important because every form of life we know on Earth needs it.

WHAT KIND OF LIFE ARE SCIENTISTS LOOKING FOR?

When scientists search for extraterrestrial life, they are not necessarily looking for intelligent aliens or creatures like those shown in science-fiction movies.

They first look for the simplest possibilities, such as microorganisms. Even finding tiny, simple life forms outside Earth would be one of the greatest discoveries in human history.

Scientists also look for signs called biosignatures—chemical substances or patterns that could indicate the presence of life.

MARS: A MAJOR TARGET 

Our neighbouring planet Mars has long been one of the most important places in the search for extraterrestrial life. Mars is cold and dry today, but scientists have found strong evidence that liquid water existed on its surface billions of years ago.

NASA's rovers, including Curiosity and Perseverance, have been studying Martian rocks and soil. Perseverance is also collecting rock samples that may help scientists understand whether Mars once had conditions suitable for ancient microbial life.

COULD LIFE EXIST ELSEWHERE IN OUR SOLAR SYSTEM?

Mars is not the only interesting place. Some moons of the outer planets are especially exciting.

Europa, one of Jupiter's moons, has an icy surface and is believed to have a vast ocean of liquid water beneath its ice.

Enceladus, a moon of Saturn, also has a subsurface ocean. Spacecraft have detected jets of water-rich material shooting from cracks near its south pole. These discoveries make such icy moons important targets in the search for possible life.

WHAT ABOUT INTELLIGENT ALIENS?

Finding intelligent extraterrestrial life would be even more extraordinary. Scientists have searched the skies for unusual radio signals that could have been produced by advanced civilisations.

Projects such as SETI (Search for Extraterrestrial Intelligence) listen for possible signals from distant worlds. So far, no signal has been confirmed as a message from an extraterrestrial civilisation.

This does not prove that intelligent life does not exist. Space is enormous, and distant civilisations may be extremely difficult to detect.

THE FAMOUS DRAKE EQUATION 

In 1961, astronomer Frank Drake proposed an equation to estimate the possible number of communicating civilisations in our galaxy.

The equation considers factors such as the number of stars, the number of planets around those stars, and the possibility of life developing on suitable planets.

However, many of the values are still uncertain. Therefore, the Drake Equation is best viewed as a framework for thinking about the question rather than a precise calculator of alien populations.

HAVE WE FOUND ALIENS YET?

No. As of today, there is no scientifically confirmed evidence of extraterrestrial life.

Scientists have discovered intriguing clues—such as ancient evidence of water on Mars, organic molecules in space, and potentially habitable environments on distant worlds—but none of these discoveries proves that life exists beyond Earth.

This distinction is important. Scientists carefully test extraordinary claims before accepting them as evidence.

WHY DOES THE SEARCH MATTER?

The search for extraterrestrial life is not simply about finding aliens. It could help us answer some of the biggest questions about our own existence.

If life were discovered elsewhere, scientists could compare it with life on Earth. We might learn whether life develops easily when the right conditions exist or whether Earth is an extremely rare exception.

Either discovery would be remarkable. Finding life elsewhere would show that Earth is not the only place where life has appeared. Not finding it, even after extensive searches, would tell us something equally important about how rare life might be.

A QUESTION THAT INSPIRES US 

The universe remains full of mysteries. Every new telescope, spacecraft and scientific discovery gives us a better opportunity to understand our cosmic neighbourhood.

Perhaps somewhere, many light-years away, life exists beneath the ice of a distant moon or on a planet orbiting another star. Perhaps intelligent beings are looking towards their own skies and asking exactly the same question:

“Are we alone?”

For now, the answer remains unknown—and that mystery is one of the greatest adventures in modern science.

DID YOU KNOW?

●Extraterrestrial simply means “from outside Earth.”

●Planets outside our Solar System are called exoplanets.

●Mars once had rivers, lakes and other environments associated with liquid water.

●Europa and Enceladus are considered promising places to investigate for environments that could potentially support life.

●Scientists search for both biosignatures of life and possible technosignatures produced by advanced technology.

Compassion and courage

SACRIFICE FOR THE MOTHERLAND 

The history of India's freedom struggle is filled with stories of courage, sacrifice and unwavering love for the motherland. Some heroes fought with weapons, while others fought with nothing but their faith, courage and self-respect. Their sacrifices remind us that patriotism is not merely about words—it is about standing firm for what we believe is right, even when the cost is our own life.

The following story, set against the backdrop of the First War of Indian Independence in 1857, tells us about an elderly temple priest who faced a remarkable moral dilemma. When a wounded British officer and his wife came to him seeking refuge, he chose humanity over hatred and protected them. But when the same officer later demanded that he insult the blood of Indian revolutionaries to save his own life, the priest refused.

His final act teaches us a powerful lesson: compassion makes us human, but the courage to protect the honour of our motherland makes us truly patriotic.

In the year 1857, the flames of the First War of Indian Independence were raging throughout Uttar Pradesh. Angered by the atrocities committed by the British forces, freedom fighters in village after village were driving the British out of their regions.

Amidst this turmoil, an elderly priest lived in an ancient Shiva temple built on a hill, far away from the village. His life was based on devotion to God and the principles of truth and compassion.

A Cry for Shelter

One stormy night, there was a loud knocking at the main door of the temple. The priest lit a lamp and opened the door. Standing before him were a British officer and his wife, both covered in blood and badly injured. Behind them could be heard the angry cries of the revolutionaries.

The British officer pleaded, “Maharaj! Please save us. The people will kill us.”

The priest faced a difficult moral dilemma. These were the very British people who had enslaved his country. Yet the people standing before him were helpless refugees seeking protection.

The priest followed the principle of Sanatan Dharma that protecting someone who seeks refuge is the highest duty and hid the couple in a secret chamber inside the temple.

The Revolutionaries Enter the Temple

Within moments, a group of brave village soldiers arrived at the temple, carrying torches and weapons. They asked,

“Priest! Has any British person taken shelter here?”

The priest replied calmly but firmly,

“This is the sacred abode of God. Here, there is neither enemy nor friend; there is only a person who has sought refuge. It is my duty to protect anyone who comes to this threshold seeking shelter.”

The crowd was deeply moved by the priest's dignified personality and devotion to truth. They bowed before him and left.

At dawn, the priest helped the British couple leave safely through a secure route.

As he departed, the British officer said gratefully,

“Today, I have witnessed true religion.”

A Cruel Test of Loyalty

A few months later, a large contingent of the British army arrived in the village to suppress the revolution. Acting on information provided by an informer, British soldiers raided the temple and arrested the priest. They took him to their military camp.

The same British officer whose life the priest had once saved was now in charge of the camp.

The priest thought that the officer would recognise him and release him with respect. But intoxicated by power and colonial arrogance, the British officer had forgotten his humanity.

In the camp courtyard, several Indian revolutionaries had been shot dead. The sacred blood of the brave sons of India was flowing on the ground.

The British officer cruelly said,

“Priest! You helped the rebels. If you want to save your life, lick the blood of these rebels lying on the ground and prove your loyalty to the British government.”

The Priest's Sacrifice

Hearing this inhuman condition, the elderly priest's self-respect and love for his motherland awakened. His eyes became red with anger. He stood upright and looked directly into the officer's eyes.

He said,

“Once, I saved your life by following the duty of humanity. But this blood belongs to the brave martyrs of my motherland. To insult the blood of my country's sons merely to beg for my life would be worse than death for me.”

The priest rejected the cruel demand with contempt. He refused to bow before the officer or compromise his principles.

On the officer's orders, the sound of gunshots echoed through the camp. The elderly priest attained martyrdom while raising the cry:

“Victory to Mother India!”

Message of the Lesson

Balancing Humanity and Self-Respect

Giving shelter to a helpless enemy is an act of compassion and humanity. However, refusing to compromise the honour of one's motherland and its martyrs represents self-respect and patriotism.

National Duty Comes First

Compassion has an important place in our personal lives. But when the honour and dignity of one's country are at stake, being willing to sacrifice one's life rather than surrender one's principles represents the true duty of a citizen.

A troll tale

THE CLEVER YOUNGEST SON 

Once upon a time, there lived a poor farmer with three sons. The farmer was growing old, and the family had a large debt to repay. One day, he called his sons and said, “We must work hard and repay our debt. Go to the forest and bring back some wood to sell.”

The eldest son went first. He walked deep into the forest and began chopping a fir tree. Suddenly, a huge troll appeared from behind the trees. It was so frightening that the boy dropped his axe.

“Get out of my forest!” the troll roared. “If I ever see you here again, I will eat you!”

The terrified boy ran all the way home. When he told his father what had happened, the farmer shook his head.

“Why are you so frightened?” he asked. “No troll ever scared me when I was young!”

The next morning, the second son went into the forest. But the moment he began chopping a tree, the same enormous troll appeared.

“Leave my forest at once!” it thundered.

The second son was even more frightened than his brother and ran home without taking a single piece of wood.

Finally, it was the youngest son’s turn. Unlike his brothers, he was not easily frightened. Before leaving, he put a large piece of cheese into his knapsack.

When he reached the forest, he calmly began chopping wood.

Soon, the troll appeared.

“What are you doing in my forest?” it roared. “Leave immediately!”

The young man looked at the troll and smiled.

“Why should I be afraid of you?” he asked.

The troll stepped closer threateningly. But the young man took the cheese from his knapsack and squeezed it tightly. The soft cheese oozed through his fingers.

“See this white stone?” he said boldly. “If you make me angry, I will squeeze you just as easily!”

The troll stared at the “stone” and became terrified.

“Please don't!” it cried. “Spare me, and I will help you chop the wood.”

The young man agreed. Together, they worked quickly and gathered a huge pile of wood.

As evening approached, the troll invited the young man to its home for dinner. There, the troll cooked a giant pot of delicious porridge.

“Let us have an eating contest!” suggested the young man.

The troll eagerly agreed, certain that it could out-eat the boy.

But the young man had a clever plan. Before sitting down, he secretly tied his empty knapsack in front of himself. As he pretended to eat, he quietly dropped spoonful after spoonful of porridge into the knapsack.

Soon, the knapsack was completely full.

The young man secretly made a small cut in it with his knife. Then he pretended to cut his own stomach.

“Look!” he exclaimed. “I have made more room in my belly. Now I can eat even more!”

The foolish troll believed him.

“If you can do that, so can I!” it cried.

Without thinking, the troll followed the young man's advice. That was the end of the foolish troll.

The young man then searched the troll's home. Hidden inside were piles of gold and silver that the troll had collected over many years.

He gathered the treasure and returned home.

His father and brothers were amazed when they heard the whole story. The gold and silver were enough to pay off their debt, and the family could finally live without worry.

The farmer proudly hugged his youngest son.

“You proved that courage is not always about being strong,” he said. “Sometimes, a calm mind and a clever idea are more powerful than great strength.”

And from that day onwards, the family lived happily and peacefully.

Moral: Courage, intelligence and presence of mind can help us overcome even the greatest challenges.

A Haven for Wildlife in the Western Ghats

BANDIPUR NATIONAL PARK 

Nestled amidst the scenic hills and forests of the Western Ghats in Karnataka, Bandipur National Park is one of India’s most beautiful and important wildlife reserves. Located mainly in Chamarajanagar district, the park is famous for its rich biodiversity, magnificent landscapes and thriving population of wild animals, especially tigers and elephants.

A PART OF A VAST WILDLIFE LANDSCAPE 

Bandipur covers an area of about 875 sq km and forms part of a remarkable network of protected forests. It is connected with the Wayanad Wildlife Sanctuary in Kerala and Mudumalai Wildlife Sanctuary in Tamil Nadu. The forests also connect with Nagarhole National Park, with the Kabini Reservoir forming an important geographical feature of the region.

Together, these protected areas form part of the Nilgiri Biosphere Reserve, which was established in 1986 under UNESCO’s Man and the Biosphere Programme. It was India’s first biosphere reserve and is one of the country’s most important conservation landscapes.

A ROYAL BEGINNING 

Bandipur has an interesting history. In 1931, the Maharaja of Mysore established a wildlife reserve in this region as a conservation measure. It was originally known as the Venugopala Wildlife Park, named after the Venugopala shrine situated on a hill in the area and associated with the Mysore royal family.

Bandipur received even greater importance after Project Tiger was launched by the Government of India in 1973 to protect and increase India’s tiger population. Bandipur was among the original nine tiger reserves selected when the project began.

Today, it is recognised as one of India’s important tiger habitats and is also a popular destination for people interested in wildlife and nature.

A LAND OF HILLS, VALLEYS AND RIVERS 

The landscape of Bandipur is a fascinating combination of hills, valleys, forests and grasslands. The Kabini, Nugu and Moyar rivers drain the region, while numerous streams, pools and water tanks provide water for wildlife.

Some of the smaller water bodies dry up during summer, while others remain perennial. These water sources are especially important for animals during the hotter months.

At one end of the park lies the spectacular Moyar Gorge, which marks the boundary between Bandipur and Mudumalai. Except for natural barriers such as the gorge, animals can move freely through the connected forest landscape.

The highest point in Bandipur is Himavad Gopalaswamy Betta, which rises to about 1,450 metres above sea level.

A RICH VARIETY OF PLANTS 

Bandipur’s vegetation consists mainly of dry deciduous forests, moist deciduous forests and shrublands. The forests are home to many valuable and characteristic Indian tree species.

Among them are teak, sandalwood, rosewood, Indian laurel, flame-of-the-forest, black myrobalan, red silk-cotton, Indian gooseberry and Indian laburnum.

The park also supports countless smaller plants, including ground orchids, medicinal herbs and colourful flowering plants. Together, these plants provide food and shelter for the diverse animal life of the region.

HOME OF THE TIGER AND ELEPHANT 

The great attractions of Bandipur are its magnificent wild animals. The tiger, Asian elephant, gaur and chital (spotted deer) are among the best-known inhabitants of the park.

Other mammals found here include the leopard, dhole (Indian wild dog), sloth bear, sambar, four-horned antelope, barking deer, common langur, striped hyena, palm civet, slender loris and Indian giant squirrel.

The connected forests are particularly valuable because large animals such as elephants and tigers require extensive areas in which to find food, water and mates. Wildlife corridors between protected areas therefore play an important role in their survival.

A PARADISE FOR BIRDWATCHERS 

Bandipur is also an excellent destination for bird lovers. More than 200 species of birds have been recorded in the region.

Among the birds found here are the Malabar grey hornbill, white-bellied minivet, honey buzzard, Indian long-billed vulture, grey partridge, jungle bush quail, pied kingfisher, Asian paradise flycatcher and lapwings.

Some birds, such as the Malabar grey hornbill and white-bellied minivet, are associated with the biodiversity-rich Western Ghats.

REPTILES OF BANDIPUR 

The park’s forests and water bodies also provide shelter to a variety of reptiles. These include the Indian rock python, mugger crocodile, Indian monitor lizard, flying lizard and Indian pond terrapin.

These reptiles form an important part of the forest ecosystem and help maintain the balance of nature.

A TREASURE OF THE WESTERN GHATS 

Bandipur is much more than a place where tourists can see wild animals. It is a vital part of a large, interconnected forest ecosystem. The forests of Bandipur, Nagarhole, Wayanad and Mudumalai together provide a continuous habitat for numerous species.

Its importance lies not only in protecting the tiger but also in conserving elephants, birds, reptiles, plants and countless other organisms that share this remarkable landscape.

Located about 220 km from Bengaluru, and around 80 km from Mysuru and 148 km from Coimbatore, Bandipur is relatively accessible to visitors.

For nature lovers, wildlife enthusiasts and students of biology and environmental science, Bandipur offers a wonderful opportunity to understand how forests, rivers, plants and animals are all connected. It is truly one of Karnataka’s great natural treasures—and an important part of India’s wildlife heritage.

Where Tennis Meets Tradition

WIMBLEDON TENNIS TOURNAMENT 🎾

Every year, tennis lovers around the world eagerly wait for one of the most prestigious sporting events—the Wimbledon Tennis Tournament. Officially known as The Championships, Wimbledon, it is the oldest tennis tournament in the world and one of the four Grand Slam tournaments. It was first held in 1877 and is the only Grand Slam tournament that continues to be played on grass courts, the original surface of lawn tennis.

A TOURNAMENT WITH A GRAND HISTORY 

Wimbledon is organised by the All England Lawn Tennis and Croquet Club (AELTC) in Wimbledon, London. The first Championship in 1877 was a men's singles event. From those modest beginnings, Wimbledon gradually grew into one of the biggest sporting events on the planet.

The present Wimbledon site on Church Road was purchased in 1920. Centre Court was constructed in preparation for the 1922 Championships, and it has since become one of the most famous sporting venues in the world.

WHY IS WIMBLEDON SPECIAL?

One of Wimbledon's most distinctive features is its grass courts. Unlike the other Grand Slam tournaments, Wimbledon retains grass as its playing surface.

Grass makes tennis particularly interesting because the ball generally travels quickly and stays relatively low after bouncing. Players need excellent reflexes, movement and serving skills to succeed on the surface.

Wimbledon is also famous for its traditions. Its perfectly maintained lawns, strawberries and cream, the famous Centre Court and the tournament's strict predominantly white clothing tradition all contribute to its unique character.

THE MAIN EVENTS 

Wimbledon features several major competitions:

- Gentlemen's Singles

- Ladies' Singles

- Gentlemen's Doubles

- Ladies' Doubles

- Mixed Doubles

There are also competitions for junior players and wheelchair athletes.

The singles titles are particularly prestigious because they bring together the world's finest tennis players. Winning a Wimbledon singles title is considered one of the greatest achievements in tennis.

FAMOUS CHAMPIONS

Over the years, Wimbledon has witnessed extraordinary champions such as Roger Federer, Novak Djokovic, Rafael Nadal, Pete Sampras, Serena Williams, Venus Williams, Steffi Graf, Martina Navratilova and Billie Jean King.

Roger Federer became particularly associated with Wimbledon, winning the men's singles title eight times. Novak Djokovic has also enjoyed remarkable success at the Championships.

In women's singles, Martina Navratilova, Serena Williams, Steffi Graf and many other champions have created unforgettable moments on the Wimbledon grass.

FIVE INCREDIBLE FACTS FROM THE WIMBLEDON COURTS 

1. A Wimbledon Final Lasted Only 54 Minutes!

The 1983 women's singles final was remarkably short. Martina Navratilova defeated Andrea Jaeger 6–0, 6–3 in just 54 minutes.

It was an extraordinarily dominant performance and remains one of the shortest women's singles finals in Wimbledon history.

2. A Player Once Ran Out of Rackets!

Goran Ivanišević was known for his fiery temperament on court. In 2000, however, his frustration reached an unusual level.

During a match at the Samsung Open in Brighton, England—not Wimbledon— he smashed all three rackets he had with him. With no suitable racket left to continue, he was forced to default from the match.

So, although this remarkable incident did not happen at Wimbledon, it is certainly an unforgettable story involving a former Wimbledon champion.

3. Roger Federer Won 105 Wimbledon Matches

Roger Federer made his Wimbledon debut in 1999, aged just 17. He went on to win eight Wimbledon men's singles titles and finished his career with 105 singles match victories at the Championships.

For many years, Federer held the record for the most men's singles match wins at Wimbledon. In 2026, Novak Djokovic surpassed Federer's total, moving beyond 105 wins.

Federer's remarkable Wimbledon career remains one of the greatest in the history of the tournament.

4. The Longest Match in Tennis History

In 2010, John Isner of the United States and Nicolas Mahut of France played a first-round match at Wimbledon that became legendary.

The match lasted an astonishing 11 hours and 5 minutes over three days. Isner eventually won with a fifth-set score of 70–68.

The full score was:

6–4, 3–6, 6–7, 7–6, 70–68

Wimbledon itself records the contest as the longest tennis match ever played.

5. Meet Rufus, Wimbledon’s Hawk! 🦅

Wimbledon has a rather unusual member of its security team—Rufus the Hawk.

Rufus is a Harris's hawk who patrols the Wimbledon grounds, helping to keep pigeons away from the courts. According to Wimbledon, he arrives at around 9 a.m. to fly around the grounds before play begins.

His job may sound unusual, but keeping birds away helps protect the courts and prevents interruptions during matches. Rufus has become something of a celebrity himself!

THE FAMOUS TROPHIES 

The winners of the Wimbledon singles events receive two of tennis's most recognisable trophies.

The men's singles champion receives the Gentlemen's Singles Trophy, while the women's singles champion receives the Venus Rosewater Dish.

These trophies represent much more than victory in a tennis tournament. They symbolise skill, determination, discipline and years of hard work.

WIMBLEDON AND INDIA 

India has also had memorable connections with Wimbledon. Indian tennis players such as Leander Paes, Mahesh Bhupathi, Sania Mirza and Rohan Bopanna have achieved notable success at the Championships, particularly in doubles and mixed doubles.

For Indian tennis fans, Wimbledon remains one of the most eagerly followed sporting events of the year.

WIMBLEDON IN 2026

The 2026 Championships were held from 29 June to 12 July 2026.

The tournament once again brought together the world's leading tennis players and continued Wimbledon's long tradition of championship tennis on grass.

WIMBLEDON AND ITS TRADITIONS 

Wimbledon is not simply about winning matches. It is also about preserving traditions that have developed over nearly 150 years.

The tournament's famous white clothing tradition dates back to the Victorian era. Wimbledon continues to maintain strict rules regarding the amount of colour players may wear on court.

Another famous tradition is The Queue, through which spectators can obtain tickets on the day of play.

The Wimbledon Lawn Tennis Museum also preserves the history of the Championships. Visitors can see famous trophies, historic clothing and equipment and learn about how Wimbledon has developed since 1877.

A SYMBOL OF EXCELLENCE 

Wimbledon has evolved enormously since its first Championship in 1877, yet it has carefully preserved its distinctive identity.

Its beautiful grass courts, famous champions, strict traditions and extraordinary stories—from a 54-minute final to an 11-hour marathon match, and even a hawk named Rufus—make Wimbledon much more than an ordinary tennis tournament.

It is a celebration of tennis, tradition, sportsmanship, determination and excellence.

DID YOU KNOW?

- 🎾 Wimbledon was first held in 1877.

- 🌱 It is the only Grand Slam tournament played on grass.

- 🏟️ Centre Court at the present site was ready for the 1922 Championships.

India’s First Hydrogen-Powered Passenger Train

🚆 NaMo GREEN RAIL 

A GREEN REVOLUTION ON INDIAN RAILWAYS 

Imagine boarding a train that does not produce diesel smoke and generates its own electricity using hydrogen. This futuristic idea has become a reality in India.

On 17 July 2026, India took a major step towards cleaner transportation when its first indigenous hydrogen-powered passenger train was flagged off between Jind and Sonipat in Haryana. The train is an important achievement for Indian Railways and India's efforts towards greener mobility. 

🇮🇳 A TRAIN MADE IN INDIA 

The hydrogen train has been designed, engineered and developed in India, reflecting the country's growing capabilities in advanced railway technology and the vision of Aatmanirbhar Bharat.

It is a 10-coach train, consisting of two Hydrogen Driving Power Cars and eight passenger coaches. It can accommodate around 2,600 passengers.

The train has a maximum approved operating speed of 75 km/h, while its design speed is 110 km/h. It operates on the approximately 89-km Jind–Sonipat section of Northern Railway. 

💧 HOW DOES A HYDROGEN TRAIN WORK?

A hydrogen train works very differently from a traditional diesel locomotive.

Instead of burning diesel, it uses hydrogen fuel cells to generate electricity.

Here is the process in simple steps:

Hydrogen + Oxygen → Electricity + Water Vapour + Heat

Hydrogen is stored in special tanks on the train.

Hydrogen enters the fuel cells.

Oxygen is taken from the surrounding air.

A chemical reaction between hydrogen and oxygen produces electricity.

The electricity powers the train's electric motors.

The main direct by-products are water vapour and heat.

So, there is no diesel exhaust or direct carbon emission at the train's point of use. 

🌱 WHY IS IT IMPORTANT?

One of the biggest advantages of hydrogen-powered trains is their potential to reduce pollution from railway transportation.

India has already made tremendous progress in railway electrification. Hydrogen technology provides another option, particularly for routes where conventional electrification may not be practical.

The Jind–Sonipat train is also a pilot project. Its operation will give Indian Railways valuable experience in hydrogen storage, refuelling, safety and everyday train operations. 

⚡ WHERE DOES THE HYDROGEN COME FROM?

A special hydrogen refuelling facility has been established at Jind.

At the facility, hydrogen can be produced through electrolysis, in which electricity is used to split water into hydrogen and oxygen. The hydrogen is then stored, compressed and supplied to the train.

The facility can store nearly 3,000 kg of hydrogen and has been developed as part of India's first integrated hydrogen railway ecosystem. 

🔋 POWERFUL TECHNOLOGY 

The train has two hydrogen driving power cars, each with a 1,200-kW power system, giving a combined power output of 2,400 kW.

It also uses lithium iron phosphate (LFP) batteries along with fuel cells and hydrogen storage systems to support its operation. 

According to the Ministry of Railways, the 10-coach train is currently described as the world's longest and most powerful hydrogen train-set on a broad-gauge platform. 

🛡️ IS HYDROGEN SAFE?

Hydrogen is highly flammable, so safety is extremely important.

The train and its refuelling system have several safety features, including systems that can detect hydrogen leaks, heat, flames and smoke. Automatic shut-off systems and continuous ventilation provide additional protection. 

🌍 BENEFITS OF HYDROGEN TRAINS 

🌱 1. Cleaner transportation

Fuel-cell trains produce water vapour and heat as direct by-products rather than diesel exhaust.

💨 2. Less air pollution

They eliminate the smoke and direct tailpipe emissions associated with diesel-powered trains.

🔋 3. Energy innovation

Hydrogen provides another way of powering trains without relying on diesel fuel.

🚆 4. Useful for non-electrified routes

Hydrogen trains could be especially useful on railway routes where installing overhead electric infrastructure is difficult or expensive.

🇮🇳 5. Encourages Indian technology

The project demonstrates India's ability to design and develop advanced clean-transport technology domestically.

⚠️ WHAT ARE THE CHALLENGES?

Hydrogen trains are promising, but the technology also faces challenges.

Producing green hydrogen requires electricity, and producing, storing, compressing and transporting hydrogen requires specialised infrastructure. Building hydrogen refuelling stations can also be expensive.

Therefore, hydrogen trains are not expected to replace all electric trains. Instead, they may become particularly useful on selected routes where they offer practical advantages.

🚆 WHAT DOES THE FUTURE HOLD?

The Jind–Sonipat project is only the beginning. Indian Railways is exploring the possibility of using hydrogen technology on other routes, including heritage railway routes such as the Kalka–Shimla line, based on the experience gained from this project. 

The launch of the hydrogen train shows how railway technology has evolved:

Steam → Diesel → Electric → Hydrogen

Each stage represents an attempt to make railway travel more efficient and suitable for the needs of its time.

🌟 DID YOU KNOW?

🇮🇳 India's first indigenous hydrogen-powered passenger train was flagged off on 17 July 2026.

🚆 It runs on the Jind–Sonipat section in Haryana.

📏 The route is approximately 89 km long.

🚃 The train has 10 coaches.

👨‍👩‍👧‍👦 It can accommodate around 2,600 passengers.

⚡ It has a combined power output of 2,400 kW.

💧 Water vapour is the main direct by-product of the fuel-cell process.

🏭 A dedicated hydrogen storage and refuelling facility has been established at Jind.

🌍 Indian Railways describes it as the world's longest and most powerful hydrogen train-set on a broad-gauge platform. 

⛽ In its initial operation, the train had travelled more than 1,200 km and saved over 3,200 litres of diesel, according to the Ministry of Railways. 

🌿 A GLIMPSE OF THE FUTURE 

India's first hydrogen-powered passenger train is much more than a new railway service. It represents a meeting point of science, engineering, clean energy and environmental responsibility.

As India looks towards a cleaner and more sustainable future, trains powered by hydrogen could become an important part of the country's green transportation journey.

**The train may run on hydrogen, but it carries a much bigger message — the journey towards a greener India has begun. 🇮🇳🌱🚆**

Moral story

THE POWER OF A POSITIVE ATTITUDE 

Once, there was a woman who believed that every day could be a good day if she chose to look at life positively.

One morning, she woke up, looked into the mirror and noticed that she had only three hairs on her head.

“Oh well!” she said with a smile. “I think I’ll braid my hair today.”

She braided her three hairs and went about her day happily. She enjoyed herself and had a wonderful day.

The next morning, she looked into the mirror and saw that she had only two hairs left.

“Hmmm…” she thought. “I think I’ll part my hair down the middle today.”

She did exactly that and went through her day with a cheerful smile. Once again, she had a grand day.

The following morning, she looked into the mirror and discovered that she had only one hair left.

“Well,” she said cheerfully, “today I’m going to wear my hair in a ponytail!”

She tied her single hair into a tiny ponytail and went about her day happily. She laughed, worked and enjoyed every moment.

The next morning, she looked into the mirror and found that she had not a single hair left on her head.

Instead of feeling sad, she smiled brightly and exclaimed,

“Wonderful! I don’t have to fix my hair today!”

She got ready quickly and went on to enjoy another beautiful day.

Moral of the Story:

We cannot always control what happens in our lives, but we can control how we respond to it.

A positive attitude does not mean that we have no problems. It means that we choose to look for possibilities instead of focusing only on difficulties.

Sometimes, changing our attitude can change the way we experience an entire situation.

Remember: When life gives you a reason to complain, look for a reason to smile!
