It’s about to happen and it may even explain 2012: Betelgeuse (known as "Beetlejuice") may be about to explode. When it does, it will produce a second sun in the sky (something that some scientists think already exists–NOTE: Subscribers can still listen to this show).
Physicist Brad Carter says the star is losing mass, a sign that it may soon collapse and explode (go super-nova). While that was happening, there would be no night sky on Earth and our planet will be showered with gamma rays and other particles. In the Huffington Post, Dean Praetorius quotes Carter as saying, "They will flood through the Earth and bizarrely enough, even though the supernova we see visually will light up the night sky, 99% of the energy in the supernova is released in these particles that will come through our bodies and through the Earth with absolutely no harm whatsoever."
He predicts this will happen by 2012. Praetorius quotes astronomer Phil Plait as saying, "Betelgeuse might go up tonight, or it might not be for 100,000 years. We’re just not sure."
