2012’s Second Sun

Earth is believed to be getting a second sun burning in the sky near the end of 2012, as the second biggest star in the universe, Betelgeuse, is dying, which will lead to “multiple days of constant daylight.”

 

Many ancient cultures 4have speculated about the appearance of a second sun and this event appears to 1tie in very closely with the December 21 2012 predictions.

 

Betelgeuse is the second 2biggest star in the universe and the eighth 3brightest in the night sky, Scientists 5have determined that the star is losing mass at a rapid rate, which indicates it will go supernova very soon.

 

The light emitted from this exploding star will be so bright that it will appear for a few weeks at the end of 2012 as a second sun in the sky. There may be little if no period of darkness or night according to senior lecturer of physics at the University of Southern Queensland, Brad Carter.

 

Earth will experience “brightness for a brief period of time for a couple of weeks and then over the coming months it begins to fade and then eventually it will be very hard to see at all,” explained the Australian scientist Brad Carter to news.com.au.

 

Scientist 6have known about this dying star which is 640 light years away from Earth, since 2005. It is believed that as Betelgeuse goes supernova it will not be harmful to Earth. “There will be neutrinos emitted during the supernova process, said University of Minnesota physics professor Priscilla Cushman, but neutrinos, even lots and lots of them, are only weakly interacting, so they won't affect life on earth,” but that is only speculation at this point.

 

The fact is, we as human beings have never experienced anything like this before so close to our home planet, and to be honest, we just don’t know for sure what this event could bring.
