Stars go boom
When a star larger than our Sun dies, it collapses and then explodes as a supernova, leaving behind clouds of searingly hot gas.
NASA’s Hubble Space Telescope has captured numerous photos of these leftover “planetary nebulae” — which actually have nothing to do with planets.
Here are 10 colorful remnants of dead or dying stars.
Supernova SN 1987A
Ring Nebula (M57)
Butterfly Nebula (NGC 6302)
Cat’s Eye Nebula (NGC 6543)
Pandora’s Cluster (Abell 2744)
In this case, that ghostly white orb in the center is whole dead galaxy.
