NASA took to Instagram to share an image showing the remains of a supernova. Which is a massive explosion that occurs at the end of a star’s life cycle. And, that’s really remarkable. NASA said the incident was caused by the death of a white dwarf star. White dwarfs are usually stationary. But in a binary system, where two stars are orbiting each other. The white dwarf gravity pulls the object out of its mate and then explodes. Something similar happened with this star.
However, “Astronomers suspect that this white dwarf star was larger than expected. Which also means that it may have died early in its life cycle,” NASA said in the post.
Named DEM L249, this white dwarf was located in a large magellanic cloud about 200,000 light-years from Earth. Moreover, the Hubble Space Telescope found it “while searching for surviving allies of white dwarf stars in supernovae in the Magellanic Cloud.”
The cosmic ribbon of air, shown in the picture in red, has been left behind by the Titanic stellar explosion. The agency said in an Instagram post, “True chart-topper, the remnants of this supernova were found to be hotter than normal Type 1a supernova remnants and more shining in X-rays.”
Separately, NASA explained through animation how a white dwarf star steals material away from a nearby stellar ally. When it reaches the decisive force, it is not able to sustain its own mass and so the star explodes and dies, creating a type 1a supernova.
The Hubble Telescope was launched in 1990 in collaboration with NASA and the European Space Agency. Since then it has relied heavily on space observation equipment by scientists because the telescope has an unobstructed view of deep space.
