For Earth to be born, our solar system needed certain isotopes which could only be formed by supernovae. But, shouldn't such a stellar violent event kill a planet-forming disk? Here is what a study says about such events and how common Earth-like bodies are.

Earth was formed with lots of cosmic rays from a supernova, and many of them could be out there

The universe will end someday, as it is expanding and stretching due to dark energy. But a South Korean scientist says this force is weakening, and the expansion has slowed down. Soon, gravity will become the bigger force and the universe will end in a Big Crunch.

Universe will collapse into one big fireball, with stars and planets sucked into a core

Uranus has not always had this name. While the planets current name might trigger a bit of laughter, its initial name generated some controversy. Here is the history of the blue-green planet name.

Believe it or not, Uranus' initial name was quite controversial, and so it was renamed

Kepler-56 is a red giant star slightly bigger than our Sun and with two planets around it. But it has a strange spin as its outer layer is moving faster and is also misaligned with its interior. A scientist thinks it is likely that it ate one of its planets, which caused this weird wobble.

Scientist thinks red giant star with a weird spin feasted on its own planet

A study has hypothesised that a cometary shower changed Earth's climate millions of years ago when humans were starting to take their place on the planet. A star likely jolted the Oort Cloud, sending the comets towards ys, which rained down on Earth.

Scientists suggest passing star rattled Oort Cloud, sending comets storming towards early Earth

The Very Large Telescope (VLT) in Chile saw the first moments of supernova SN 2024ggi 22 million light-years away. This helped them deduce what a supernova looks like right when it is first formed.

Scientists see first moments of a dying star as it turns into a supernova

A team of astronomers at Yonsei University has found that the universe has slowed down. It is not expanding at a fast pace any more as hypothesised by scientists. This means that dark energy has weakened. So what is really going on in the universe?

Is the universe coming to a halt? Shocking study says it has slowed down

A planet located 620 light-years away in the constellation Chamaeleon is acting like a young star, chomping down on matter at the rate of six billion tons per second. Scientists are amazed to see the infant planet going through such a growth spurt.

The discovery of an Einstein Cross stunned scientists who spotted an anomaly. An Einstein Cross has four images at straight angles, but this one had a fifth image at the centre. What was it? Researchers think it is a dark matter halo. 

Einstein Cross, a cosmic wonder of space-time bending - What's hiding in this new discovery?

What is an Einstein Cross? Foreground galaxies warp space-time and bend the light from a distant galaxy to create four distinct images. But scientists were shocked when they saw a fifth image while observing a new galaxy. What was it?

Dark matter breakthrough? Einstein Cross with five images stuns scientists. What is it?

The universe as we know it was only discovered 100 years ago. Before that, scientists thought that the Milky Way was the entire universe. But one observation by Edwin Hubble changed that forever, introducing us to a world where our galaxy was almost negligible.

Voyager discovered a massive storm on Neptune called the Great Dark Spot, with winds faster than any hurricane on Earth. Now, its story offers not only insights into space weather, but reflections on human challenges. Know more below.

Is there a 'Great Dark Spot' on humanity? Here's what Voyager’s data says about the universe’s biggest mysteries

To reach the halo would take on the order of two million years or more. By then, Earth’s continents and even the Sun’s brightness will have changed.

In 2 million years, Voyager 2 could drift into the Galactic Halo but what is it?
