It's about to hit the cosmic wall! Just 17500 years to go! [/quote] There's a reason large numbers are referred to as [i]astronomical[/i]. [quote:Uncle Alyosha:MV8yMTIzMDQ1XzM1ODIyNzY4XzMzQjREQTQx] [quote:Upheval:MV8yMTIzMDQ1XzM1ODIyMjg0X0EyNEE3OTBG] It would be cool to see it go super nova! It could happen from the next day to 100,000 years from now. It is 600 Light years away and no danger to us, but what a show it would be!! [/quote] 600 light years won't protect you from that magnitude of explosion. Go inside...and bring in the tomatoes... [/quote] Don't lie. :book: [/quote] He is correct, at that range we would get blasted by radiation from the explosion..game over amounts. [/quote]
Roughly 1000 times the diameter of our Sun and shining 100 000 times more brightly, Betelgeuse's impressive statistics come with a cost. For this star is likely on its way to a spectacular supernova explosion, having already swelled into a red supergiant and shed a significant fraction of its outer layers...
...The new far-infrared view from Herschel shows how the star's winds are crashing against the surrounding interstellar medium, creating a bow shock as the star moves through space at speeds of around 30 km/s...
... An intriguing linear structure is also seen further away from the star, beyond the dusty arcs. While some earlier theories proposed that this bar was a result of material ejected during a previous stage of stellar evolution, analysis of the new image suggests that it is either a linear filament linked to the Galaxy's magnetic field,
or the edge of a nearby interstellar cloud that is being illuminated by Betelgeuse.
If the bar is a completely separate object, then taking into account the motion of Betelgeuse and its arcs and the separation between them and the bar, the outermost arc will collide with the bar in just 5000 years, with the red supergiant star itself hitting the bar roughly 12 500 years later.
