The shredded stays of a stellar explosion glow shiny crimson in a surprising new picture from the Hubble Space Telescope.
The vibrant cosmic ribbons of fuel are the results of an explosion of a white dwarf star that reached the tip of its life, often known as a Type 1a supernova. This supernova remnant, formally often called DEM L249, is situated within the Large Magellanic Cloud (LMC), which is a satellite dwarf galaxy of the Milky Way and among the many closest galaxies to Earth.
Hubble snapped this new picture of DEM L249 whereas surveying the LMC searching for surviving stellar companions of white dwarf stars that had already exploded, in accordance with a statement from NASA.
“White dwarf stars are usually stable, but in a binary system — two stars orbiting each other — a white dwarf can gravitationally pull so much matter from its companion that it reaches critical mass and explodes,” NASA officers stated within the assertion.
DEM L249 is a very uncommon supernova remnant, believed to have been an enormous and comparatively younger white dwarf star when it met its demise.
Using NASA’s Chandra X-ray Observatory and the European Space Agency’s (ESA) XMM-Newton space observatory, astronomers discovered that the fuel of DEM L249 was hotter and shone brighter than remnants of different Type 1a supernovas.
Therefore, given heavier stars expel extra fuel, the white dwarf star that created DEM L249 is believed to have been extremely large when it exploded. In flip, the star would have died earlier in its lifecycle, in accordance with the assertion.
