ScienceDaily (Sep. 6, 2012) — In the quest for the cosmic origins of heavy elements, Heidelberg scientist Dr. Camilla Hansen has established that silver can only have materialised during the explosion of clearly defined types of star. These are different from the kind of stars producing gold when they explode. The evidence for this comes from the measurement of various high-mass stars with the help of which the stepwise evolution of the components of all matter can be reconstructed. . . .

The death of a star

Uploaded by  on May 9, 2007

3-d video from NASA’s Chandra X-Ray Observatory. It shows the explosion of SN 2006gy. 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. . . .
