Universe Today – Subaru Telescope Sees 1800 Supernovae

Japanese astronomers have captured images of an astonishing 1800 supernovae. 58 of these supernovae are the scientifically-important Type 1a supernovae located 8 billion light-years away. Type 1a supernovae are known as ‘standard candles’ in astronomy.

A supernova is a star that has reached the end of its life and exploded brilliantly. Supernovae brighten the sky for up to six months, and can outshine their host galaxy. These type 1a supernovae, or standard candles, are particularly useful because of their steady light. Since their light doesn’t fluctuate much, they are ideal for accurately measuring their distance from Earth. Standard candles are used to measure the expansion rate of the universe.
