Using data that's three decades old, NASA scientists say they've figured out what happens to Venus' heat when it's lost to space — and discovered that the planet's surface may be "squishy" enough for it to be hemorrhaging its internal warmth...This Venusian discovery stems from astronomers trying to understand the planet's surface, which unlike Earth does not have tectonic plates to explain where its heat goes.

Credit: OSSOS team ================================================================================================ An international team of astronomers have discovered a new dwarf planet orbiting in the disk of small icy worlds beyond Neptune. The new object is roughly 700 kilometers in size and has one of the largest orbits for a dwarf planet. Designated 2015 RR245 by the International Astronomical Union's Minor Planet Center, it was found using the Canada-France-Hawaii Telescope on Maunakea, Hawaii, as part of the ongoing Outer solar system Origins Survey (OSSOS). "The icy worlds beyond Neptune trace how...

Astronomers spot new planet It is most distant body found orbiting star other than the sun 01/07/2003 By ALEXANDRA WITZE / The Dallas Morning News SEATTLE - Astronomers marked a milestone Monday in their hunt for planets beyond the solar system, announcing the discovery of the most distant planet ever detected orbiting a star other than the sun. The new planet is about 5,000 light-years (about 30 million billion miles) away. The discovery is the first accomplished by watching a star's light dim as a planet slides across its disk - a technique recently polished by astronomers. Such eclipses...
