supernova

Summary:

regarding NOVA T PYXIDIS, how much effect can this have on your planet? and also how long does it actually take to become a supernova? i hope 3000 light years seems to be VERY far away to affect us in any way.. i hope it's just some dumb mistake the press or that scientist made..

thank you for your attention and you guys are AWESOME!

Press releases are generally not written by the scientists. However, it appears that the scientist in this case (Sion) made a mistake in his calculations, and used the radiation figures from a much larger type of explosion called a Gamma Ray Burst (GRB). If one of those happened within 3000 light years (which it does not appear that it could, there are no candidate stars in that range) then it could damage the earth's atmosphere (i.e., strip the ozone layer). It could not "wipe us out" as the Telegraph's article said.

Not something worth worrying about, since it'll only happen in 10 million years.

Well, not only that, but look at this snippet from that article:

During Sion's presentation, he was challenged by one of his peers in the audience, Prof. Alex Fillipenko from Berkeley Astronomy Department. Apparently Sion had possibly miscalculated the damage that could be caused by a T Pyxidis supernova.

It seems that Sion had used data for a far more deadly gamma-ray burst (GRB) exploding 3,260 light-years from Earth, not a supernova. T Pyxidis certainly isn't expected to produce a GRB.

I knew that it would be only a matter of time before this report finally had some sort of adverse affect on those who are already wary or afraid of the rumors and theories surrounding 2012.

By the way; Hello, Bryan.

Astro and Andy both are correct, there's really nothing to worry about with this star finally dying.

As Astro had also stated, the calculations were also incorrect which only contributes to the controversy to come and also controversy that I'm absolutely not looking forward to facing at any point in time in the near future.

On an off-topic note: Hello, everyone. Guess who's back. :)

Hi Bryan,
Thanks for your nice comment. That would be a fitting finale for the 2012hoax project.

I'd volunteer TickTock to be the host, but 12/31 at his place is likely to be cold. We need a member in Hawaii!!

Well, we have one in Australia. It'll be summer there.
