Astrophysicists at a UK university have found a quartet of white dwarf stars which they say are in the process of consuming exoplanets that were once similar in composition to Earth.

NASA's Kepler Mission Extended Through 2016

Funding for NASA's planet-seeking Kepler Mission, which was scheduled to expire in November, has been renewed for four more years, the US space agency announced on Wednesday.

Getting to Know the Goldilocks Planet
2012-04-02 06:11:33

NASA's Kepler spacecraft is discovering a veritable avalanche of alien worlds. Recent finds include planets with double suns, massive "super-Earths" and "hot Jupiters," and a miniature solar system.

A New Take On Planetary Accretion
2012-02-29 09:39:21

The prevailing model for planetary accretion, also called fractal assembly, and dating back as far as the 18th century, assumes that the Solar System’s planets grew as small grains colliding chaotically, coalescing into bigger ones, colliding yet more until they formed planetesimals.

Earth Siblings Can Be Different

The study of the photospheric stellar abundances of the planet-host stars is the key to understanding how protoplanets form, as well as which protoplanetary clouds evolve planets and which do not.

The Kepler Space Telescope (KST), NASA’s planet-hunting observatory, has discovered 26 confirmed planets within 11 new solar systems.

Volunteers Asked To Help Look For Earth-Like Planets
2012-01-16 14:11:33

Volunteers are being asked to join in the hunt in looking for nearby planets that could support life. Volunteers can visit the Planet Hunters website to see time-lapsed images of 150,000 stars that were taken by the Kepler space telescope.

Image 1 - Kepler Finds Three Smallest Exoplanets
2012-01-12 04:24:07

A team of astronomers led by scientists at the California Institute of Technology (Caltech) has discovered the three smallest confirmed planets ever detected outside our solar system.

Could A Two Sun System Support A Habitable Planet Or Moon?
2012-01-11 09:44:13

A team of University of Texas at Arlington (UTA) astrophysicists are suggesting that a habitable Earth-like planet could exist in a distant solar system recently discovered by NASA’s Kepler Space Telescope.

Planetary and Space Science is a peer-reviewed scientific journal established in 1959 and published by Elsevier 15 times per year. As of May 2012, the editor-in-chief is Rita Schulz (The Netherlands). The journal publishes original research articles and short communications. The main focus is on solar system processes which encompass multiple areas of the natural sciences. Research that involves planetary and space sciences involves many disciplines. Celestial mechanics is part of these...

Terrestrial Planet Finder -- The Terrestrial Planet Finder is a proposed NASA telescope system capable of detecting extrasolar terrestrial planets. In May 2002, NASA chose two TPF mission architecture concepts for further study and technology development. Each would use a different means to achieve the same goal - to block the light from a parent star in order to see its much smaller, dimmer planets. That technology challenge has been likened to finding a firefly near the beam of...

Planet -- A planet is a body of considerable mass that orbits a star and that doesn't produce energy through nuclear fusion. Until recently, only nine were known (all of them in our own Solar system). As of the end of 2002 over 100 are known, with all of the new discoveries being extrasolar planets. Astronomers often call asteroids minor planets, and call the larger planetary bodies (those which are commonly called planets) major planets. Planets within the solar system can be...

Gas Giant
2004-10-19 04:45:41

Gas Giant -- A gas giant is a generic astronomical term invented by the science fiction writer James Blish to describe any large planet that is not composed mostly of rock or other solid matter. Gas giants may still have a solid core - in fact, it is expected that such a core is probably required for a gas giant to form - but the majority of its mass is in the form of gas (or gas compressed into a liquid state). Unlike rocky planets, gas giants do not have a well-defined surface. There...

Extrasolar Planet
2004-10-19 04:45:41

Extrasolar Planet -- An extrasolar planet is a planet orbiting around a star other than the Sun. Extrasolar planets were first discovered in the 1990s as a result of improved telescope technology, CCD and computer-based image processing which allowed far more accurate measurements of stellar motions. The first extrasolar planets were reported by the astronomer Aleksander Wolszczan in 1993, orbiting the pulsar PSR 1257+12. Subsequent investigation has determined that they are only planets...
