Twin Stars Could Be Visible From Earth By 2012. By Dean Praetorius | HuffingtonPost.com Earth could be getting a second sun, at least temporarily.
Dr. Brad Carter, Senior Lecturer of Physics at the University of Southern Queensland, outlined the scenario to news.com.au. Betelgeuse, one of the night sky’s brightest stars, is losing mass, indicating it is collapsing. It could run out of fuel and go super-nova at any time. When that happens, for at least a few weeks, we’d see a second sun, Carter says. The Star Wars-esque scenario could happen by 2012, Carter says... or it could take longer. But doomsday sayers should be careful about speculation on this one. In fact, a neutrino shower could be beneficial to Earth. UPDATE: To clarify, the news.com.au article does not say a neutrino shower could be beneficial to Earth, but implies a supernova could be beneficial, stating, "Far from being a sign of the apocalypse, according to Dr Carter the supernova will provide Earth with elements necessary for survival and continuity.

Scientists have found the biggest and oldest reservoir of water ever--so large and so old, it’s almost impossible to describe.
The water is out in space, a place we used to think of as desolate and desert dry, but it's turning out to be pretty lush. Researchers found a lake of water so large that it could provide each person on Earth an entire planet’s worth of water--20,000 times over. Yes, so much water out there in space that it could supply each one of us all the water on Earth--Niagara Falls, the Pacific Ocean, the polar ice caps, the puddle in the bottom of the canoe you forgot to flip over--20,000 times over.
The water is in a cloud around a huge black hole that is in the process of sucking in matter and spraying out energy (such an active black hole is called a quasar), and the waves of energy the black hole releases make water by literally knocking hydrogen and oxygen atoms together. The new cloud of water is enough to supply 28 galaxies with water.
