Is Betelgeuse about to blow? (going supernova in weeks or just another breathless rumor?)

This is just one more problem inherited from the Bush administration.

I still have to say that it would be awe-inspiring if it actually blew within our lifetimes.

Respectfully request your permission to ping you to this post if it does blow? Just to give an understatement of the century award? ;)

Betelgeuse might go up tonight, or it might not be for 100,000 years.

I guess that's covering the bases. I'll go out on a limb myself and will predict a devastating hurricane on the East Coast with a direct hit on Savannah, GA. If not this summer, than anytime over the next 1,000 years.

So if you live in the Savannah area, better get busy stockpiling candles and canned food.

The only thing we know for sure is if it does blow...

Bush's fault!

Discover Magazine is late to the party. The changes in Betelgeuse have been observed and commented on for several years now.

“Betelgeuse, considered a supergiant star, is so large that it would reach to Jupiter’s orbit in our solar system. But at a radius of about five astronomical units, the star has shrunk in size since 1993 by a distance equivalent to Venus’s orbit.”

“The distance to Betelgeuse is not known with precision but if this is assumed to be 640 light years, the star’s diameter would be about 950 to 1000 times that of the Sun. Betelgeuse has a color index (B-V) of 1.86 and is thought to have a mass of about 20 solar masses.[3]

It is likely that Betelgeuse will become a supernova.[3][19] Considering its size and age of 8.5 million years – old for its size class – it may explode within the next thousand years—if it hasn’t already.[19] Since its rotational axis is not toward the Earth, Betelgeuse’s supernova would NOT cause a gamma ray burst in the direction of Earth large enough to damage its ecosystem even from a relatively close proximity of 640 light years.[19]

A Betelgeuse supernova could easily outshine the Moon in the night sky.[19] It will likely be the brightest supernova in recorded Human history, easily outshining SN 1006. After it explodes, it will likely linger for several months, being visible in the daytime sky and lighting up nighttime skies in the Solar System for a long time, after which the “right shoulder” of Orion will disappear forever.”

After getting some peanuts and a few pints of bitter down at the local pub of course.

Wha? Daylight savings gives us more sunshine? Wow, the power of congress is amazing.

Can you ping me too? I don't want to miss the show when it explodes!

That is a pretty good Nova, but not a Super Nova, in my opinion. A Super Nova would be one that is parked in my garage :>)

Sure, because doubling the insolation on the earth couldn't possibly disrupt the internet.

Actually, I'll probably be cowering in the bunker. I'm practical like that. ;)
