The Longest Day? Get ready for two suns in the sky

Earth could have two suns when Betelgeuse, the second largest star in the constellation Orion, explodes... 

This mind-blowing event could happen as soon as this year when Betelgeuse, one of the brightest stars in the sky, explodes – causing enough brightness to illuminate both day and night.

The only real issue of debate is over when exactly this event will happen. Some scientists say the blast might have already happened and we just haven’t seen the light rays yet.

Brad Carter, senior lecturer of physics at the University of southern Queensland in Australia, told the London Telegraph that the blast could happen in the next few months . . . or any time over the next million years. Talk about an open-ended timeframe.

This video isn't exactly about the phenomenon described above, but is interesting and gives an indication of what we may see if the two sun event is visible in our lifetime.
