Death of a White Dwarf Star Creates Cosmic Red Ribbons of Gas, NASA Shares Photo


NASA shared a photo on Instagram that shows the remnants of a supernova, a massive explosion that occurs at the end of a star’s life cycle. And, it’s really remarkable. NASA said the event was created by the death (explosion) of a white dwarf star. A white dwarf is usually stationary. But in a binary system, where two stars are orbiting each other, a white dwarf’s gravity pulls matter away from its companion and then explodes. Same thing happened with this star.

NASA “Astronomers suspect that this white dwarf star was more massive than expected, which also means that it may have died earlier in its lifecycle,” Post said.

This white dwarf, named DEM L249, was located in the Large Magellanic Cloud, about 200,000 light-years from Earth. Hubble Space Telescope found it While “looking for surviving companions of white dwarf stars that go supernova in the Magellanic Cloud.”

The cosmic ribbons of gas shown in the image in red are left behind by the Titanic stellar explosion. “A true chart-topper, this supernova remnant was found to contain more hot gas and brighter X-rays than the remnant of a typical Type 1a supernova,” the agency said. instagram Post.

Separately, NASA explained through animation How a white dwarf star steals material from a nearby stellar companion. When it reaches critical mass, it is no longer able to maintain its own mass and so the star explodes and dies, forming a Type 1a supernova.

NS Hubble Telescope, NASA and The . a joint collaboration of European Space Agency, was launched in 1990. Since then it has been one of the most relied upon instruments for space observation by scientists as the telescope has an unobstructed view of deep space.
