Latest Extrasolar planet Stories
Planetary Resources, a company best known for its plans to mine asteroids, is launching an expanded crowdfunding campaign through Kickstarter.
A team of astronomers is working on a technique capable of detecting faint dust clouds around other stars where Earth-like planets could be hiding. This new technology could dramatically improve the odds of discovering planets with conditions suitable for life.
Astronomers writing in the Astrophysical Journal say they have found that many of the stars and planets discovered are larger than previously thought.
Scientists announced during the American Astronomical Society’s national meeting in Indianapolis this week that they have discovered a hot Saturn-like planet in another solar system 700 light-years away.
When scientists began seeking out planets outside of our solar system, they anticipated seeing systems much like our own.
Astronomers using the European Southern Observatory's Very Large Telescope (VLT) have imaged possibly the faintest exoplanet so far.
Astronomers have determined that white dwarfs cool more slowly in the early stages of their life than models have previously predicted.
The smallest space telescope to ever hit the cosmos will soon start observing the largest stars in history.
NASA announced yesterday that its Kepler space telescope is stuck in standby mode, but one professor is already coming up with ideas to try and revive the observatory.

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.
