STELLAR EXPLOSIONS

Following are some links to images of supernovae, primarily the Crab nebula and the 1987 supernova in the Large Magellanic Cloud (LMC), an irregular galaxy near our Milky Way galaxy.

X-ray spectrum from XMM-Newton for Cassiopeia-A (CAS A), a supernova remnant cloud from a stellar explosion over 300 years ago. Clearly shows distribution of heavy elements identified in X-ray spectrum.

X-ray evidence linking the hypernova concept (explosion of very massive star) with gamma ray bursts, from XMM-Newton telescope. This is extremely important evidence in the search for the cause of these most energetic events in all of astronomy.
