SN 2006gy Supernova/Hypernova, animation of

This animation shows an artist’s rendition of how SN 2006gy exploded. The extremely massive star shed some of its outer layers in a large eruption prior to its violent collapse. The explosion then plows into the expelled cooler gas, creating a brilliant light show. Astronomers think Eta Carinae in the Milky Way could explode in the same way at any time. (Credit: NASA/)
