Earth could be getting a second sun, at least temporarily.

I saw two moons the other night.... down by the river some folks were skinny dippin'

Were they shiny or going nova?

Interesting bit of info. It takes a star billions of years to burn its fuel but it only lasts a few seconds as soon as it starts fusing iron. At least thats what I have been told.

I would love to see the nova in my lifetime.

We could get an exact time and date of the showing of the explosion. Simply take a couple of the observers and put them 1 light year towards the star. When they see it go piff they can come back and tell us when to see it ourselves.

Story has been around before, nothing now.  Some things right, but plenty of hyperbole too.  Debunked here:  http://blogs.discovermagazine.com/badastronomy/2011/01/21/betelgeuse-and-2012/

When the Aliens abducted me last year, we took a shortcut around Betelgeuse and it looked fine too me.
