Latest Extrasolar planet Stories
NASA announced on Wednesday that its Kepler spacecraft was sitting in safe mode once again, possibly putting an end to its high-accuracy observations.
Since its launch in 2009 the Kepler spacecraft has identified more than 2,500 planet candidates in our galaxy. Of these, several hundred have been confirmed as planets by ground based observatories.
The field of exoplanet research – the study of planets outside of our solar system – has exploded in the last decade as new instruments have come online that have dramatically increased our ability to find new worlds.
In the search for life beyond Earth scientists face significant challenges. Given the great distances and faint signatures of the alien worlds that we have found, discovering which ones are even potentially habitable is difficult.
The Holy Grail in the search for planets outside our solar system is finding one that could potentially support life. But theoretical physicist Sara Seager from the Massachusetts Institute of Technology argues perhaps we are being too restrictive on what habitable planets could possibly look like.
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.

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...
- Sleep; the state or condition of being asleep.
- The state or condition of numbness of a part due to pressure on a nerve: as, the obdormition of a limb.
