How do solar systems form? Specifically, why do some systems form smaller rocky worlds, while others are dominated by gas giants? A recent study led by Trey Mack, a graduate student in astronomy at Vanderbilt University, may have found the answer.

Astronomers Using Kepler Telescope Discover First Earth-Sized Exoplanet Within The Habitable Zone
2014-04-17 15:09:39

A potential game changer in the hunt for life outside our neighborhood has just been discovered about 493 light years away. Using NASA’s Kepler Space Telescope, astronomers have found a rocky planet that is similar in size to Earth

New theory advanced for how collapsed stars become polluted -- pointing to ominous fate that awaits planet Earth.

Space Sunflower Could One Day Help Snap Pictures Of Planets

A spacecraft that looks like a giant sunflower might one day be used to acquire images of Earth-like rocky planets around nearby stars.

Exoplanet Hunter Selected By European Space Agency
2014-02-20 04:31:01

The European Space Agency is preparing a new space mission, named Planetary Transits And Oscillations Of Stars (PLATO), is scheduled for launch in 2024 with a key goal of discovering and learning about extrasolar planets, or "exoplanets."

Superhabitable Exoplanet

A new paper argues that some planetary bodies may hold 'superhabitable' environments even more suitable for life than those found here on Earth.

Habitable Zone Larger Than Believed
2014-01-08 14:32:50

A new paper published in the journal Planetary and Space Science claims planets that were once thought uninhabitable may actually be able to contain life after all.

Rocky Exoplanets Too Hot To Support Life: Kepler Data
2014-01-07 05:07:34

NASA’s Kepler spacecraft team reported details about five new rocky planets on Monday at the American Astronomical Society meeting in Washington.

Dawn Mission Data Offers New Evidence On Vesta Asteroid's History
2013-11-07 15:32:00

A new paper published in the journal Nature rewrites the history of the giant asteroid Vesta, which was recently visited by NASA’s Dawn mission. It was during this mission that the spacecraft used its visible and infrared mapping spectrometer instrument to map out the surface of the asteroid, leading to some new theories and ideas of the space rock.

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...
