When a star explodes between clouds of gas and dust, it becomes very bright. During this event called a supernova, astronomers have come to know about a star that survived even after the supernova explosion. After the explosion, it is now brighter than before.

The US space agency NASA’s Hubble Space Telescope has detected this star. It is a white dwarf star. This white star is said to be the remnant of a star that destroyed itself in a supernova explosion.

Curtis McCulley, lead author of the study published in the ‘Astrophysical’ journal and senior astrophysicist at Las Cumbres Observatory in California, said the white dwarf star resides in a spiral galaxy called NGC 1309. It is about three quarters of our galaxy. This star is located at a distance of 108 million light years from Earth. Significantly, there are several types of supernovae depending on the size, composition and strength of the explosion.

Living ‘zombie’ identified for the first time
This star is helping scientists better understand ‘Type Lax’ supernovae. In such an explosion, the stars are not destroyed, but they leave behind a remnant. Scientists have called these stars zombie stars. He is dead, but not completely. Scientists have detected about 50 supernovae of this type so far, but a living white dwarf ‘zombie star’ has been identified for the first time.

‘Zombie’ is associated with other stars
This white dwarf star (zombie) is associated with another star in orbit. This pair is called the binary system. But due to the binary system, the mass of this star reached equal to that of the Sun. This caused thermonuclear reactions in its core and caused a supernova explosion. The star should have died after this explosion. But the scientists were perplexed, because this had never happened.
