Latest Extrasolar planet Stories
Some people think aliens are a conspiracy theory or an impossibility, but statistically it's possible that extra-terrestrial life forms (ETs) could exist in our galactic neighborhood.
Astronomers discovered that in very rare cases, an exoplanet can spiral around the axis connecting its two stars.
This super-Jupiter is the closest exoplanet for which an image and a spectrum have been obtained, and it's a good picture of what Jupiter could have looked like back in the good old days.
This telescope takes the night shift and constantly scans the night sky for planets so that we can get some shut-eye.
You could name a planet after your mom or your cat, or even your favorite TV character.
This new exoplanet appears to be just too big for its star and it’s got the astronomers frantically scratching their heads.
Experts hunting for extraterrestrial life on extrasolar planets and elsewhere in the solar system are joining forces in what NASA is calling “an unprecedented initiative dedicated to the search for life on planets outside our solar system,” the US space agency announced Monday.
Astronomers have probed deeper than before into a planetary system 130 light-years from Earth. The observations mark the first results of a new exoplanet survey called LEECH (LBT Exozodi Exoplanet Common Hunt), and are published yesterday in the journal Astronomy and Astrophysics.
Thanks to NASA’s Spitzer Space Telescope and a technique known as microlensing, a team of astronomers has located one of the most distant exoplanets ever discovered – a remote gas planet located approximately 13,000 light-years from Earth.
Good news! Experts have analyzed thousands of exoplanets in our galaxy and the calculations show that billions of those stars could have planets 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...
