Latest Extrasolar planet Stories
NASA announced on Wednesday that its Kepler mission has discovered 715 new planets orbiting 305 stars. The space agency said that 95 percent of the newly discovered worlds are smaller than Neptune.
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."
High-altitude balloons have long been used by scientists who study the Earth, the sun and the stars to gain a better view of their targets by carrying their telescopes far into the stratosphere.
NASA's Kepler space telescope mission will be honored with the National Space Club's preeminent award, the Robert H. Goddard Memorial Trophy, in March.
Tatooine, a fictional planet with two stars that is best known as the home of Luke Skywalker in the Star Wars movie franchise, may not be as farfetched as one might think.
Scientists using the Very Large Telescope (VLT) created the world’s first map of the weather on the surface of a brown dwarf.
A new paper argues that some planetary bodies may hold 'superhabitable' environments even more suitable for life than those found here on Earth.
An international group of astronomers has discovered a new, roughly Neptune-sized exoplanet orbiting the brightest star in a binary system more than 400 light years from Earth, according to a study appearing in the most recent edition of The Astrophysical Journal.
A team of Japanese astronomers has located evidence of a giant planetary system forming around a young star named HD142527, and their discovery that could change existing theories on how planets form and provide new insights into the formation of a vast array of different planetary systems.
Scientists have successfully measured the masses of approximately 60 exoplanets discovered by the Kepler space telescope – research that will help them determine the composition of these planets and ultimately whether or not they are capable of supporting life.

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...
