NASA said the Hubble Space Telescope has captured an image of bands of gas left by a giant star explosion known as a supernova.
NASA flaunted a photo of an extremely rare phenomenon on Twitter. “This latest image from @NASAHubble quickly caught our attention. A true supernova envelope contains hotter gas and shimmers more in X-rays than what is left of a Type 1a supernova.” He states that “these cosmic bands of gas left behind by a giant star explosion known as a supernova. DEM L249 is a remnant of a Type 1a supernova, the death of a white dwarf.”

small white dwarf astronomical body, It is about the size of the Earth. It consists of a decomposing substance that emits, among other things, visible radiation. It arises after nuclear reactions stop in a low to medium mass star.
“It’s usually stable, but in a binary system – two stars orbiting around each other – A white dwarf can gravitationally extract a lot of matter from its companion, It reaches a critical mass and explodes,” NASA writes.
The longest lunar eclipse since the fifteenth century. Will we see them in Poland?
NASA has announced that the longest lunar eclipse in centuries is approaching. It should be visible in some places around the world, but also in …
Astronomers discovered that his The gas is hotter and brighter under X-rays than what is left of a typical Type 1a supernova. Researchers believe it was larger than expected. “Heavier stars were spewing out more gas – which also meant that they would have died earlier in their life cycle,” she added. .
Search for survivors of the fellow white dwarf
The Hubble Space Telescope captured this image while searching for surviving companions of white dwarfs who went to a supernova in the Large Magellanic Cloud.
