Exploding Star

A star on the brink of exploding as a spectacular supernova has been glimpsed by international astronomers.
The star flared up suddenly last February, briefly becoming 1,000 times brighter than normal.
RS Ophiuchi is close to destroying itself in a nuclear explosion called a type 1a supernova, scientists report in the journal Nature.
