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] So now we have two liars. Why do you lie? :book: [/quote] "A near-Earth supernova is a supernova close enough to the Earth to have noticeable effects on its biosphere. Depending upon the type and energy of the supernova, it could be as far as [b]3000 light-years away[/b]. Gamma rays from a supernova would induce a chemical reaction in the upper atmosphere converting molecular nitrogen into nitrogen oxides, depleting the ozone layer enough to expose the surface to harmful solar and cosmic radiation. This has been proposed as the cause of the Ordovician–Silurian extinction, which resulted in the death of nearly 60% of the oceanic life on Earth. In 1996 it was theorized that traces of past supernovae might be detectable on Earth in the form of metal isotope signatures in rock strata. Iron-60 enrichment was later reported in deep-sea rock of the Pacific Ocean. In 2009, elevated levels of nitrate ions were found in Antarctic ice, which coincided with the 1006 and 1054 supernovae. Gamma rays from these supernovae could have boosted levels of nitrogen oxides, which became trapped in the ice. http://en.wikipedia.org/wiki/Supernova Don't call me a liar, bitch. [/quote] You're a liar. "Depending upon the type and energy of the supernova" Betelgeuse doesn't cut it. Making statements you do not know for a fact to be true is lying. :book: [/quote] And you know for a certainty which type of supernova Betelgeuse will be do you? [/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.
