BIG.....mind blowingly BIG....betelgeuse supernova

[squirtyflower]

Nearby star Betelgeuse has been noticably shrinking over the past decade indicating that it may by now have gone supernova, at 600 light years away.


If it does blow it will depend on the axis if we are in danger or not. It isn't the explosion that is the killer.......its the x and gamma rays shooting from the poles like highly energized death rays. If one of those is pointed in our direction we are in serious trouble.

If its 600 light years away then the X-rays and Gamma rays won't reach us for 600 years as they also travel at the same speed as light.

Re: BIG....................mind blowingly BIG....

Ive only just found this thread Allan, "what a great topic and the pictures are fierce". Whenever you hear the old chestnut that "we are the only civilisation in the universe," the more you think its a load of bolox. My mate set up his tri-pod to view this flickering star looking object, he left it for 20mins, and when he went back to it, the object had moved to near enough out of frame. "I'm getting more and more interested in what exactly is out there", although i have some way to go to get to the knowledge of the OP and some of the other contributors to this thread. Just slightly off the theme, and dont mean to ambush your thread Allan,but, !where do we stand on the belief/non-belief of life on other planets, or solar systems, particularly the Reptillian agenda".(and please, "leave the silly responses for another time".)

It wasn't the star that moved mate, it was you and the Earth rotating away from it!

Oh and in answer... There is definitely other solar systems and probably life out there somewhere but where and how numerous...? We're looking at other planets and their moons in the solar system where there's water/ice for bacterial life as we think this is necessary, along with an energy source... and if we do find something then the probabilities of "intelligent" life go down dramatically.

Reptilian agenda? Oh please!

Indeed! And the chances of it pointing straight at us, from that distance, are pretty remote. Not impossible but then again, nothing is!

So far though its only shrinking and not losing any brightness or gaining any.

Thing is........we have no idea how the whole supernova process works up close. We only see the extreme aftermath in any detail.

This is one to keep your eye. 15% of a stars mass over 15 years is not something that you would think could happen. We are taught these events take billions, millions and thousands of years to happen. So its possible we are seeing the lasts moments before a supernova as everything begins to speed up.

Article about it in New Scientist... http://www.newscientist.com/article/dn17282-betelgeuse-the-incredible-shrinking-star.html

Also the 1st movie is a computer generation "intended to approximate the real star Betelgeuse".... http://antwrp.gsfc.nasa.gov/apod/ap001222.html

Interesting though eh...?

Robots to the rescue!

Hopefully that will happen at the latter part of the time-scale (1000 years), but then we will only have to worry about Yellowstone National Park, a comet/asteroid hitting and nuclear war! ;-)

(And of course Reptilian Sex-offenders, who also rule countries! ;-) )

5,000–20,000 km/s, or roughly 3% of the speed of light.

So we've got time for another drink then?

I can see it now. The FA Cup Final at Wembley, two minutes to go with City 1-0 up against United courtesy of Jo (who wasn't cup tied). Suddenly, a Gamma Ray Burst hits the Earth and ends the world for ever.

Match abandoned. Still no trophy since '76!
