When a massive star exploded in the Large Magellanic Cloud, a satellite galaxy to the Milky Way, it left behind an expanding shell of debris called SNR 0519-69.0.

Here, multimillion degree gas is seen in X-rays
from Chandra (blue). The outer edge of the explosion (red)
and stars in the field of view are seen in visible light from Hubble.
