TV. Planet Hunters. "Diamond" Planet Found; May Be Stripped Star. An exotic planet as dense as diamond has been found in the Milky Way, and astronomers think the world is a former star that got transformed by its orbital partner.
The odd planet was discovered orbiting what's known as a millisecond pulsar—a tiny, fast-spinning corpse of a massive star that died in a supernova. Astronomers estimate that the newfound planet is 34,175 miles (55,000 kilometers) across, or about five times Earth's diameter. In addition, "we are very confident it has a density about 18 times that of water," said study leader Matthew Bailes, an astronomer at the Swinburne Centre for Astrophysics & Supercomputing in Melbourne, Australia.

How the universe appeared from nothing. MacGregor Campbell, consultant There's no such thing as a free lunch, or so the saying goes, but that may not be true on the grandest, cosmic scale.
Many physicists now believe that the universe arose out of nothingness during the Big Bang which means that nothing must have somehow turned into something. How could that be possible? Due to the weirdness of quantum mechanics, nothing transforms into something all the time. Heisenberg's uncertainty principle states that a system can never have precisely zero energy and since energy and mass are equivalent, pairs of particles can form spontaneously as long as they annihilate one another very quickly.

Climate Simulation Reveals New Candidate That Could Support Earth-Like Life. Hottest planet is hotter than some stars - space - 19 January 2011. Astronomers have found the hottest planet yet, a gas giant with a temperature of nearly 3200 °C, which is hotter than some stars.
A collaboration called the Super Wide Angle Search for Planets (SuperWASP) announced hints of the planet's existence in 2006. The group had observed periodic dimmings of the parent star possibly caused by a planet about 1.4 times the size of Jupiter passing in front of the star once per orbit. Follow-up measurements confirmed the planet's presence in 2010, showing distortions of the star's light spectrum that could only be due to a planet's influence. The measurements showed the planet's mass is less than 4.5 times that of Jupiter. Called WASP-33b, the planet orbits its star at less than 7 per cent of Mercury's distance from the sun, whipping around the star once every 29.5 hours.
