Supernova are one of the universe's most cataclysmic events. If a planet is too close, it will be sterilised, even destroyed. When massive stars run out of nuclear fuel in their core, they produce x-rays and blast waves of fast particles that would render a planet like Earth uninhabitable. Watch this story to know how a star exploded 1.9 billion light-years away and our ozone layer took the hit.

What if a Supernova exploded close to earth?

A supernova explosion is one of the most spectacular events in the universe. During the explosion, huge energy is released. However, this can also spell doom for other planets in its vicinity. Watch this story to know how a supernova 'destroyed' some of earth's ozone for a few minutes in 2022

Gravitas: A supernova can tear apart a planet's atmosphere

In a mind-baffling discovery, scientists have found that a supernova explosion billions of light-years away was so powerful that it 'temporarily destroyed' some of the Earth’s Ozone layer in 2022.

NASA launched a new sounding rocket on Sunday to study a stellar event in the Cygnus Loop, which is a supernova remnant that took place 20,000 years ago. Cygnus is about 2,600 light years away from the Earth.

Scientists now have established why the red supergiant star Betelgeuse turned dim between 2018 and 2020, dismissing theories that suggested that the star might be entering the last stage of its evolution—Supernova or the ultimate explosion.

A remarkably stunning and equally captivating image recently captured by the Hubble Space Telescope showed a distant galaxy that scientists say was the stage for a recent supernova explosion.

In the latest study, scientists have suggested that a newly discovered supernova, which is 21 million light-years from Earth, can turn into a beacon for aliens to communicate.

Aliens likely to communicate through newly discovered supernova, claim scientists

Astronomers have shared a photo of a star collapsing on itself, called a supernova, in the Pinwheel Galaxy, about 21 million light-years away from Earth. The cosmic event was witnessed through the Gemini North telescope atop Mauna Kea in Hawaii by Japanese astronomer Koichi Itagaki on May 19.

The existence of human life on Earth is under siege by a new terrifying threat. Astronomers have confirmed a new danger to the Earth. Beyond the control of humans, this threat is likely to reach us from deep space. Astronomers using the Chandra X-ray Observatory and other telescopes have identified a dangerous phase. X-rays which are generated by the explosion of stars can affect life on planets 100 light-years away. This also includes our planet, Earth.

Will exploding stars trigger an extinction-level event on Earth?

The James Webb Space Telescope recently captured one of the dramatic exits of stars in space, as they exploded to form supernovae. The details of the Cassiopeia A, which was the remnant of one such explosion of stars, were clearly captured by the telescope.

Astronomers have reported that a gamma-ray explosion recorded last year in October was possibly the brightest ever to have hit Earth since the beginning of human civilisation.

'Absolutely monstrous': Brightest gamma-ray burst was a 1-in-10,000-years event, scientists say

A star's rare and fleeting phase on the cusp of death was captured by NASA's James Webb Space Telescope. NASA on Tuesday released images of WR 124, a rare Wolf-Rayet star present in the constellation Sagittarius, at a distance of 15,000 light-years from Earth.

Stars may appear to twinkle forever but like us, they have a finite lifespan. Stars of certain size put on quite a show before biting the dust. They bid adieu in a massive blast known as a supernova.

Astronomers revealed images of star graveyard in the Milky Way Galaxy. Supernova, the largest explosions takes place in space. Watch further to know more.

Supernova, the largest explosion, takes place in space

Supernova is the actual explosion of a star! When a star reaches end of its lifetime, depending on its size, it explodes. The enrgy gets dissipated in all directions in the space.

Supernovas are some of the biggest explosions in the Universe. These supergiant blasts represent death of a star. Very small percentage of stars in the Universe sign off in this spectacular way.
