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. Supernova Blast: Giant Star Eta Carinae to Explode Any Day. When the sun finally dies some 5 billion years from now, the end will come quietly, the conclusion of a long, uneventful life. Our star will, in a sense, go flabby, swelling first, releasing its outer layers into space and finally shrinking into the stellar corpse known as a white dwarf.

Things will play out quite differently for a supermassive star like Eta Carinae, which lies 7,500 light-years from Earth. Weighing at least a hundred times as much as our sun, it will go out more like an adolescent suicide bomber, blazing through its nuclear fuel in a mere couple of million years and exploding as a supernova, a blast so violent that its flash will briefly outshine the entire Milky Way. The corpse this kind of cosmic detonation leaves behind is a black hole. For Eta Carinae, that violent end might not be long in coming, according to a report in the latest Nature. But as the Nature report makes clear, that understanding may now be at hand.

It gets even better. NASAs Cassini Space Probe Finds New Saturnian Ocean. It's hard enough for kids to remember all the known oceans and seas — Atlantic, Pacific, Indian, Norwegian, Barents — and now they can add one more to the list: the Enceladan Ocean. The name is lovely, and the place is nifty, but there's not much chance of visiting it soon. It's located on Enceladus, one of Saturn's 66 known moons.

While Enceladus has been familiar to us since it was first spotted in 1789, the discovery of its ocean, courtesy of the venerable Cassini spacecraft, is a whole new and possibly game-changing thing. Enceladus has always been thought of as one of the more remarkable members of Saturn's marble bag of satellites. For one thing, it's dazzlingly bright. The percentage of sunlight that a body in the solar system reflects back is known as its albedo, and it's determined mostly by the color of the body's ground cover. Life In the Universe: Easy or Hard? The new images revealed that the cracks indeed widen and narrow and do so more than was once thought.
