Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have found wildly misaligned planet-forming gas disks around the two young stars in the binary system HK Tauri.

Industrial pollution could help in the Search for Extraterrestrial Intelligence (SETI), claim Harvard-Smithsonian Center for Astrophysics (CfA) researchers who have started looking for signs of pollutions on other worlds.

exoplanets need oceans to be habitable
2014-07-22 04:02:47

While many previous studies on habitable planetary conditions have focused on the atmosphere, a new study from UK researchers at the University of East Anglia has found that the dynamics of a planet’s ocean is crucial to supporting life.

Many scientists believe we are not alone in the universe. It's probable, they say, that life could have arisen on at least some of the billions of planets thought to exist in our galaxy alone -- just as it did here on planet Earth.

Space missions generally fall into three different categories: small, medium, and large. Dull naming conventions aside, the various mission types really tell the story of the scale of the projects. But make no mistake; even “small” missions can have a big impact.

Worldwide Contest To Name Exoplanets And Their Host Stars
2014-07-09 03:48:54

For the first time, in response to the public’s increased interest in being part of discoveries in astronomy, the International Astronomical Union (IAU) is organizing a worldwide contest to give popular names to selected exoplanets along with their host stars.

Planetary System Gliese 581

Gliese 581g, described as one of the most Earth-like planets when it was originally discovered four years ago, probably does not exist, researchers from Penn State University and the University of Texas at Austin report in the latest edition of the journal Science.

Potentially Habitable Exoplanet With Earth-Like Temperatures Found
2014-06-27 08:24:53

Astronomers have discovered a new, potentially habitable Super-Earth believed to possess temperatures comparable to those found here, but with much larger seasonal shifts, provided the atmosphere is similar to our planet.

Researchers from University College London and the University of New South Wales have reportedly developed a new, more powerful and more accurate way to detect extraterrestrial life that focuses on methane.

SPHERE first light

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
2012-05-28 10:21:45

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
2004-10-19 04:45:41

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...
