EXPLOSIVE! ???This dark, tangled web formed in a very violent fashion — it is a supernova remnant, created after a massive star ended its life in a cataclysmic explosion and threw its constituent material out into surrounding space. This created the messy formation seen in this image from our @NASAHubble Space Telescope, with threads of red snaking amidst dark, turbulent clouds.

This object is situated in the Large Magellanic Cloud, a dwarf galaxy that lies close to the Milky Way. The remnant is likely the result of a Type Ia supernova explosion; this category of supernovae is formed from the death of a white dwarf star that grows by siphoning material from a stellar companion until it reaches a critical mass and then explodes.

When explosions like this have a well-known luminosity, they can be used as markers for scientists to measure distances throughout the universe and learn more about what’s out there.
