//** RED SUPER GIANT Red supergiants typically span several hundred times the diameter of the Sun and have masses of more than 10 times that of the Sun. Red supergiants    are     supergiant         stars     of Spectral type K or M. They are the largest stars in the universe in terms of     volume     not size, although they are not the most massive in perimeter. Some of the best known red supergiant is Betelgeuse and Antares. The five largest known red supergiants in the Galaxy are VY canis Majoris, VV Cephei A, V354 Cephei, RW Cephie and KW Sagittarii, which all have radii about 1500 times that of the sun Stars with more than about 10 solar masses after burning their hydrogen become red supergiants during a phase called the “helium-burning phase”. The red supergiant phase is extremely short-lived, lasting only a few hundred thousand to a million years. at most before ending in a    supernova SUPERNOVA A            supernova             is a       massive explosion. Supernovas are extremely luminous and cause a burst of radiation that often briefly outshines an entire      galaxy      , before fading from view over several weeks or months. During this short interval, a supernova can              radiate               as much       energy       as the       sun       could emit over its life span.

Here are some videos I found on Youtube about a RED SUPERGIANT and SUPERNOVA. http://www.youtube.com/watch?v=RgfbjHz_UTo&feature=related http://www.youtube.com/watch?v=BS88G5WBcfQ&feature=related http://www.youtube.com/watch?v=S03vDKvva4g&feature=PlayList&p=235CDD4B3F7F862B&index=19&playnext=4&playnext_from=PL
