However now experts say it is not likely to happen soon and it will happen far enough away that it will not hurt Earth - hopefully...
US astronomer Phil Plait noted on his blog that a supernova would have to be no farther than 25 light years away to "fry us with light or anything else and Betelgeuse is 25 times that distance".
The story at www.news.com.au predicted that a giant explosion will occur, tens of millions of times brighter than the sun, and suggested the event could happen before 2012.
Terming the reports about the Betelgeuse's impending 2012 explosion as `pure conjuncture,' experts have elaborated that the fact that it has become a red giant are indications enough that its destined to explode and become a supernova; however, there is no reason to believe that the explosion will happen anytime in the near future.
Moreover, noting that the Betelgeuse's explosion, whenever it happens, will be so distant that it will not harm the Earth, US astronomer Phil Plait, who writes for Discovery News, said that a supernova would have to be no farther than 25 light years away to "fry us with light or anything else and Betelgeuse is 25 times that distance."
The conjecturing that the Betelgeuse will explode in 2012, and may even reach the Earth, was triggered by an Australian news site News. com. au story, which predicted that the star's massive explosion will be tens of millions of times brighter than the sun.
