G21.5-0.9: A Supernova's Cosmic Shell
NASA APOD
COSMIC MESSAGE
This cosmic shell, G21.5-0.9, is the remnant of a supernova explosion. A star nearly 20 times the mass of the Sun blasted away its outer layers. As the debris cloud expanded, shock waves heated the gas, causing it to glow in X-rays. This process creates shells that can be observed across the universe.
