Latest Extrasolar planet Stories
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.
A new discovery, made possible by an international team of astronomers, has located the first confirmed Earth-mass planet occulting, that is -- passing in front of -- its host star.
A new technique developed by a team at MIT could help scientists determine the mass of exoplanets, using just their transmission spectra.
University of Arizona astronomers are scratching their heads after discovering the most distant orbiting planet to date which is throwing a wrench in planet formation theories.
Scientists debate the criteria for trying to determine what makes a planet habitable and how many exoplanets there are out there.
You may have thought that NASA's Kepler spacecraft was finished. Well, think again. A repurposed Kepler Space telescope may soon start searching the sky again.
Researchers using new theoretical models have created a new method to simplify the search for Earth-like planets. The new models help rule out the possibility of Earth-like conditions on certain planets outside of our solar system.
New statistical analysis of data obtained by NASA’s now-retired Kepler spacecraft has revealed that one out of every five sun-like stars have at least one Earth-sized planet in the habitable zone.

Image Caption: Artistic concept of a planetary system. Credit: Wikipedia/NASA/JPL-Caltech The term Astronomy encompasses a broad range of topics, including the study of stars, galaxies, and planets. In order to focus on the different areas of study, many subfields of astronomy emerge. One such area is the study of planets known, appropriately, as Planetary Astronomy. Observational Planetary Astronomy Even within the field of Planetary Astronomy, there are several divisions to...
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 -- A terrestrial planet is a planet that is mostly composed of silicate rocks and may or may not have a relatively thin atmosphere. The term is derived from the Greek word for Earth, so an alternate definition would be those planets that are more Earth-like than not. Terrestrial planets are very different from gas giants, which may or may not have solid surfaces and are composed mostly of hydrogen and helium in various physical states. Only one terrestrial planet,...
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 -- 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...
