[QUOTE]Betelgeuse, one of the night sky's brightest stars, is losing mass, indicating it is collapsing. It could run out of fuel and go super-nova at any time. When that happens, for at least a few weeks, we'd see a second sun. There may also be no night during that timeframe. The explosion could also cause a neutron star or result in the formation of a black hole 1300 light years from Earth.
But doomsday sayers should be careful about speculation on this one. If the star does go super-nova, Earth will be showered with harmless particles. "They will flood through the Earth and bizarrely enough, even though the supernova we see visually will light up the night sky, 99 per cent of the energy in the supernova is released in these particles that will come through our bodies and through the Earth with absolutely no harm whatsoever".
To clarify, the news.com.au article does not say a neutrino shower could be beneficial to Earth, but implies a supernova could be beneficial, stating, "Far from being a sign of the apocalypse, according to Dr Carter the supernova will provide Earth with elements necessary for survival and continuity."
Dr. Carter stressed that there is no way of knowing when the star may go supernova. U.S. astronomer Phil Plait added, "Betelgeuse might go up tonight, or it might not be for 100,000 years. We're just not sure."[/QUOTE]

That was much farther away though, and a smaller star?
Seriously though, that would be so cool if it happens.
Maybe you should learn to duck more often? Those big lips must hurt, when they fly out and smack you in the head! ;)
Case in Point...
If such event would happen, for how long this another "sun" would really visible for us?
Seconds, minutes, hours, days, weeks, months, years? I suppose it depends on many things, but I might as well just ask from the bright minded scientists of Green party.
And i was going to go for George Clooney as the 2nd biggest star in the universe, but his lack of breasts deterred me.
If George Clooneys breasts would go nova, would the Betelguiseans see it?

Angelina Jolie's lack of breasts is overcompensated for by her lips...
Proxima Centauri is so tiny little fly shit err.. dwarf that it would have to brighten by insane amount to make it remarkable in any way.
Its apparent brightness is well beyond limit of human vision while Betelgeuze shows up 10 magnitudes brighter from over hundred times bigger distance.
In "direct" numbers using absolute brightness Proxima Centauri's brightness is ~0.0017 "suns" while for Betelgeuze it's estimated to be somewhere in class of 140 000 suns.
