The shredded remains of a stellar explosion glow bright red in a stunning new photo from the Hubble Space Telescope.

The vibrant cosmic ribbons of gas are the result of an explosion of a white dwarf star that reached the end of its life, also known as a Type 1a supernova. This supernova remnant, officially known as DEM L249, is located in the Large Magellanic Cloud (LMC), which is a satellite dwarf galaxy of the Milky Way and among the closest galaxies to Earth.

Hubble snapped this new photo of DEM L249 while surveying the LMC in search of surviving stellar companions of white dwarf stars that had already exploded, according to a statement from NASA.

    From my records, first aristarchus submission to be accepted since August 12. But let's stick to the science, people. White dwarf type 1-A, in the Large Magellanic Cloud? This is significant. Supernovae remnants are hard to find!

    I've blown better clouds out my ass.

      I am sure you have. But, define "better" in an astrophysical sense, if you will? You could compare the Veil Nebula, but it is much closer to us, though not as close as yours.

        Congratulations on making a submission that actually fits into SN. Are you putting your recent insanity behind you? The meds are working?

          The insanity is not mine, it is the insanity of my opponents. They get angry, because they are not too smart. It's OK, I can handle it. But about this supernova remnant, you are aware that in order for a planet like ours to form, the proto-planetary disk that formed our Sol must have contained the products of earlier supernova explosions, to create elements more dense than iron. Like Gold, Bismuth, Uranium, and Unobtainium. So finding a remnant, in a orbital dwarf galaxy? Amazing.
