Credit: NASA Watched pots, as they say, never boil. 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 | A month in space: April 2012 | Science. 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. 2012 March 12 - The Scale of the Universe Interactive.
