Pyxidis

According to Edward Sion, Professor of Astronomy and Physics at Villanova University, T Pyxidis may be in fact a "ticking time bomb," and potential threat to the Earth if it were to go supernova, which it may do sometime in the future, though very, very far in the future on our timescale: by Scion's calculations, at least 10 million years.

There remains some doubt as to whether T Pyxidis will go supernova at all.

T Pyxidis, which lies in the constellation Pyxis, is what is called a recurring nova.

T Pyxidis has had five different outbursts over the course of observations of the star.

The distance estimate to T Pyxidis, revised to 3,260 light-years from the previously estimated distance of 6,000 light-years has prompted a reconsideration of the details about the white dwarf.

A supernova within 100 light-years of the Earth would likely be a catastrophic event for our planet, but something as far out as T Pyxidis may or may not damage the Earth.

Scientists are now predicting that the end will come when T Pyxidis, a supernova, explodes.

But since T Pyxidis is 3300 light years away it would take 3300 years before the radiation reached us.

A white dwarf star in the T Pyxidis system is known to be a recurrent nova, undergoing thermonuclear eruptions around every 20 years.
