In this interactive activity from NOVA Online, learn about a type of exploding star - a Type Ia supernova - that is so bright that astronomers can measure the distance to the galaxy in which it resides, and even learn which elements make...

Details of the brightest supernova of modern times - supernova 1987A in the Large Magellanic Cloud. There are many links for additional information.

Supernovae are divided into two basic physical types, including a description of supernova types and how they are classified based on the existence of hydrogen spectral lines. Definitions of key terms are provided.

In this interactive activity from NOVA Online, learn about a type of exploding star a Type II supernova that is so large it has a mass 10 times greater than the mass of our Sun.
