Understanding these explosions would help solidify baseline measurements about the speed and size of the universe’s expansion, as astronomers rely on light from these explosions to calculate distance in space. This image represents the high-energy, X-ray remnants of one of these explosions, which occurred some 4,500 years ago in the Milky Way galaxy
