Earth rotates around itself once a day. For Sun this duration is of 1 month. Other planets in our solar system have varying durations. But a single rotation in 25 seconds?

This star spins around itself once every 25 seconds

NASA launched a first-of-its kind mission on Saturday to study Jupiter's Trojan asteroids, two large clusters of space rocks that scientists believe are remnants of primordial material that formed the solar system's outer planets.

Searching for extra-terrestrial life has been preoccupation of scientists and creative folks. The idea of us not being alone in this universe on this rock we call Earth is somewhat assuring.

Scientists catch unexpected radio signals from distant stars

No two galaxies are exactly alike. Rather each galaxy in the universe is considered to be like a fingerprint. There may be similarities between two galaxies but it is almost inconceivable that two galaxies would be identical twins of each other.

Mystery of two 'identical galaxies' solved

Astronaut Thomas Pesquet has a fanbase of his own! The European Space Agency astronaut is perched on the International Space Station (ISS). And from there, he clicks beautiful pics of Earth and space.

Earth and Venus are somewhat similar planets when it comes to size. But there are vast differences. Earth is moderate and supports life while Venus is quite literally hellish.

Think your life is hell? All the life's misery burning you to the core and you craving for escape from all the agony? Think about a planet that literally has to bear rain of blazing hot liquid iron.

Hot, liquid iron rains on this planet and temperature can hit 2k mark

NASA posts spectacular image of things across the universe. One may be forgiven to think that NASA's lenses are always focussed at distant stars and galaxies. The space agency posts n-number of photos of distant celestial bodies after all!

What if an asteroid is headed on a collision course? What would we do to escape the fate of dinosaurs? Well, we have nuclear weapons that can possibly be fired at the asteroid.

A comet and an asteroid are chalk and cheese. The difference between these two is perhaps as large as the distance between respective places where they usually hang out in space A comet comes from outer space.

An asteroid or comet? This space rock is a combination of both

We all are used to looking at pictures of galaxies with less-than-impressive galactic centre. But NASA has now shared a brilliant image of a galaxy that looks like a celestial eye.

NASA has captured image of 'eye in the sky'

All astronomers, professional and amateur, know that planet Jupiter is a prominent presence in the night sky. Thousands across the world point their telescopes at the biggest planet in the solar system and its moons.

Winds on Jupiter are speeding up and no one knows why

Talk about comets or asteroids coming anywhere near us and mind immediately goes back to what happened to dinosaurs. It just needed a space rock to end the reign of those fearsome reptiles who dominated nearly the entire foodchain.

A super-huge comet is hurtling through space towards solar system

NASA is splitting its human spaceflight department into two separate bodies - one centered on big, future-oriented missions to the moon and Mars, the other on the International Space Station and other operations closer to Earth.

The asteroid belt between Mars and Jupiter was formed amid formation of our solar system. Whatever material was left after formation of the Sun and the planets was scattered in form of asteroids.

This asteroid may have formed its own moons

Search for alien life has a bit of excitement and glamour associated with it. Movies and other forms of popular media have fuelled the frenzy. So much so that in an event of an alien attack on Earth, many of us would go "Cool!

Searching for alien life? Beware of viruses!

Leave Earth and its protective atmosphere along with its magnetic field and you will get bombarded with all sorts of cosmic raditions. These radiations are deadly and high exposure may even cause death.

There may be a way to protect astronauts from radiation on Martian surface

Search for alien life has been favourite topic of filmmakers and scientists alike. Whether we are alone in the universe is a question that has not got a definitive answer yet.

An object near galactic centre is sending radio signals

NASA's Perseverance rover has collected its first Mars rock samples, NASA confirmed on Monday. The samples will be brought back to Earth during future missions. "I've got it!

Universe literally has millions of galaxies and each one of them has a tale to tell. A photo of all of these space specks reveal a lot about them and space itself.

Brilliant photo of a galaxy reveals fascinating details

Nothing more needs to be said about how Mars occupies a place of fascination in human mind. It has been revered as a God, feared in horoscopes. But it surely makes for a unique view in the night sky with its red glory.

ESA posts brilliant pics of landslide on Mars

Space is a wonderful mystery! It has glamour that mesmerises our minds. Rockets lifting off, probes examining planets in our solar system, even going beyond the boundary of it is something that enthralls us.

Journey to Mars is full of danger, but here's the safe way

Sun is a source that sustains all life on Earth. But there will come a time when the Sun will begin to run out of the fuel a billion years from now. At this time, Sun will expand in size and literally burn our planet.

Ex-NASA scientist's Earth-saving idea involves stealing energy from Jupiter

Asteroids are serious business (ask Dinosaurs. They aren't here but). One nudge and things on Earth will literally shake to the worst extent possible. Imagine what a full-blown collision might do.

Asteroid termed 'potentially hazardous' by NASA is coming near Earth
