Just picking this up on various sites.
T.Pyxidis a twin star approximately 3260 light years away is expected to go supernova with the force of 20 billion, billion, billion tones of TNT.
Risk is that due to its close proximity the thermonuclear blast could destroy Earth's ozone layer rendering the planet uninhabitable.
HAPPY NEW YEAR!
The white dwarf star has been observed absorbing matter at extreme rates which resulted in novas up to 1987 (or 67) depending which reports you read when they stopped, so it is a classic supernova waiting to happen.
Should we be bothered?
Well, the light we are seeing from this star has been travelling for 3260 years so if the star explodes today then the blast wont reach us for another 3260 years (phew!), however, if the star went pop 3260 years ago......
