Scientists at the American Astronomical Society's 215th meeting, in Washington DC, said earlier this week that new observations of T Pyxidis in the constellation Pyxis (the compass) using the International Ultraviolet Explorer satellite, indicate the white dwarf is part of a close binary system with a sun, and the pair are 3,260 light-years from Earth and much closer than the previous estimate of 6,000 light-years.
The white dwarf in the T Pyxidis system is a recurrent nova, which means it undergoes nova (thermonuclear) eruptions around every 20 years. The most recent known events were in 1967, 1944, 1920, 1902, and 1890. These explosions are nova rather than supernova events, and do not destroy the star, and have no effect on Earth. The astronomers do not know why the there has been a longer than usual interval since the last nova eruption. But they fear it might be a SUPERNOVA waiting to happen!!!
The story goes on to say that if it did go supernova, we would all die. Almost STAR TREK XI's Romulas fate, if you think about it.
That even at that distance, the radiation would wash over our world and destroy the ozone layer and kill all life. But, if it did happen, we wouldn't even know until we were dead since gamma radiation and light travel at the same speed...
Does my life insurance cover this?
