Sharing what ive just read. I wonder what the Betelgeuse star looks like now (if we can see it).
in Summary:
Betelgeuse losing mass
Explosion will create "new sun"
May be set for 2012 appearance
The red supergiant star Betelgeuse is getting ready to go supernova, and when it does Earth will have a front-row seat. The explosion will be so bright that Earth will briefly seem to have two suns in the sky.
The star is located in the Orion constellation, about 640 light-years away from Earth. it's predicted to explode in the very near future. Of course, the conversion from stellar to human terms is pretty extreme, as Betelgeuse is predicted to explode anytime in the next million years.
But still, whether the explosion occurs in 2011 or 1002011 (give or take 640 years for the light to reach Earth), it's going to make for one of the most unforgettable light shows in our planet's history. For a few weeks, the supernova will be so bright that there will appear to be two stars in the sky, and night be will indistinguishable from day for much of that time. So don't count on getting a lot of sleep when Betelgeuse explodes, because the only sensible thing for the world to do will be to throw a weeks-long global supernova party.
The interwebs is being flooded with doomsday theories saying the impending supernova confirms the Mayan calendar’s prediction of the Armageddon in 2012.
