Supernovae are important astronomical objects. They tell us about how stars die and are used as measuring sticks to investigate distant galaxies. But there is still some uncertainty as to how the supernova process proceeds in some cases.

Supergiant Star -- A star of 15 solar masses exhausts its hydrogen in about one-thousandth the lifetime of our sun. It proceeds through the red giant phase, but when it reaches the triple-alpha process of nuclear fusion, it continues to burn for a time and expands to an even larger volume. The much brighter, but still reddened star is called a red supergiant. Betelgeuse, at the shoulder of Orion, is the best-known example. Absolute luminosities may reach -10 magnitude compared to +5...
