The red giant is 400 times larger than our Sun and pulsates, changes temperature and varies in brightness by a factor of over 750 times across a 390-day period.

It's a class of stars known as a Mira variable star and, at its peak brightness, is 5,000 times brighter than the Sun .

When the white dwarf star in this system comes close to the red giant, its gravitational pull siphons hydrogen gas from the larger star.

This gravitational pull eventually causes spontaneous nuclear fusion, causing it to explode like a hydrogen bomb.
