Latest Extrasolar planet Stories
Uwingu announced on Wednesday the launch of the world's first "Adopt-a-Planet" campaign, allowing the public an opportunity to adopt planets.
The newest addition to our planet-hunting arsenal, the HARPS spectrograph, has characterized two new worlds. Planets KOI-200 b and KOI-889 b are Jupiter-like planets that orbit very close to their host stars.
A dead star, known as a white dwarf, will eventually cool down and fade away because it has no energy source. However, a new study suggests that white dwarfs can still support habitable planets.
A SETI Institute scientist has been chosen to lead the design, development and operations of the data processing center for NASA’s next-generation successor to the Kepler Mission, the Mountain View, California-based organization announced on Friday.
Astronomers have discovered what could be considered the most Earth-like planet ever found outside our solar system, nestled around a sun-like star in the Lyra constellation.
While the concept behind Uwingu is intriguing, IAU says it is misleading because their naming campaigns have no bearing on the official naming process.
NASA has selected five planet hunters to receive the 2013 Carl Sagan Exoplanet Postdoctoral Fellowships. The fellowship, named for the late astronomer, was created to inspire the next generation of explorers seeking to learn more about planets, and possibly life, around other stars.
Using a state-of-the-art telescopic imaging system, astronomers are now able to see planets that orbit distant stars, known as exoplanets, more easily and in greater detail.
Astronomers may have made, for the first time, a direct observation of a planet forming inside a thick disc of gas and dust in a relatively nearby stellar system.

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...
