Besides, even if they did, why watch them? You know exactly what boiling water looks like. But I bet you don't know what it looks like in outer space. Here are seven everyday occurrences including the boiling of water that happen very differently in the microgravity environment of low-Earth orbit, plus explanations why.
Planet X? New Evidence of an Unseen Planet at Solar System's Edge. A planet four times the size of Earth may be skirting the edges of the solar system beyond Pluto, according to new research.
Too distant to be easily spotted by Earth-based telescopes, the unseen planet could be gravitationally tugging on small icy objects past Neptune, helping explain the mystery of those objects' peculiar orbits. The claim comes from Rodney Gomes, a noted astronomer at the National Observatory of Brazil in Rio de Janeiro. Gomes presented his recently completed computer models suggesting the existence of the distant planet at a meeting of the American Astronomical Society in Timberline Lodge, Ore., earlier this month. Astronomers who attended the talk find Gomes' arguments compelling, but they say much more evidence is needed before the hypothetical planet can be crowned as real. Sedna, for example, swings around the sun in an extremely elongated orbit — tracing out a very long oval. Unknown entity New planet or old star? A field of galaxies, asteroid mining, Earthrise on the moon, and a rubber chicken called Camilla – in pictures. In our pick of the most fabulous space imagery from last month, we feature galaxies as numerous as the grains of sand on a beach, hi-tech tycoons' dream of mining asteroids, a recreation of Earthrise over the moon as seen by Apollo 8 … and a rubber chicken.

Scientists Discover The Oldest, Largest Body Of Water In Existence. 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. Solar System Scope.
