Astronomers witness the explosive death of a giant star for first time.

For the first time, astronomers have observed the final days and death throes of a red supergiant star before its final collapse and massive explosion into a supernova.

Supernovas are usually only detected after they happen, although a few of a different type have been caught in the act of exploding. In this case, scientists detected the star in its final stages about 130 days before it detonated, and they were able to watch it grow progressively brighter and, at last,  blow up.
