What Is A Supernova? ; By Andrea Thompson; Senior Writer; posted: 04 May 2009; 08:44 am ET; ... Type I supernova: star accumulates matter from a nearby neighbor until a runaway nuclear

From our earthly vantagepoint, we cannot see every supernova that occurs in our galaxy because interstellar dust obscures our sight.

Supernova occurs at the end of a star's lifetime, when its nuclear fuel is exhausted and it is no longer supported by the release of nuclear energy.

Whenever this phenomenon occurs (i.e., Mcore > ~ 5 solar masses), the supernova creates a black hole from the core of the original star.

There are not enough supernova remnants observed in our Galaxy to support an ancient Universe - the numbers observed actually are indicative of a young Universe. ... When this occurs, the star will

A Type 1 Supernova occurs where there are binary stars, or two stars that orbit closely with each other. ... A Type 2 Supernova occurs when the life of a star with great mass come to an end.

When a high mass star (final mass greater than 1.4 solar masses) collapses at the end of its life a supernova occurs.

When a supernova occurs, the majority of the matter in the star is blown out at nearly the speed of light. If you are close, you don't get to watch it very long before you are blown to bits.

This data shows how difficult IR measurements will be when the supernova occurs this close to the center of a galaxy.
