Super-Jupiter Planet Observed By Astronomers Using the Subaru Telescope
2013-08-06 05:23:10

There are several techniques employed by astronomers to discover planets orbiting distant stars. The most popular techniques seek transits - where a planet will pass directly in front of a star, blocking part of its light.

New Explorer Mission Chooses The 'Goldilocks Orbit'
2013-08-01 08:05:06

Principal Investigator George Ricker likes to call it the "Goldilocks orbit" -- it’s not too close to Earth and her Moon, and it's not too far. In fact, it's just right.

Spitzer Spots Hula Hoop Star System

NASA's Spitzer Space Telescope has discovered a young stellar system containing three developing stars that work together like a hula hoop.

Pulsating Star Observations Shed New Light On Planetary Systems
2013-07-30 09:10:51

An international team of scientists has devised a method for measuring the internal properties of a star that offers more accurate assessments of the star's orbiting planets.

NASA Attempts 'Hail Mary' To Recover Kepler Space Telescope
2013-07-19 14:23:40

NASA is launching a last-ditch "Hail Mary" attempt to try and bring its Kepler mission back to life. The US space agency said that over the next week, the Kepler team will attempt tests to explore recovery of the spacecraft's reaction wheels, which failed back in May

Planets May Keep Warmer In A Cool Star System
2013-07-19 13:49:17

According to a new study published in the journal Astrobiology, planets orbiting cooler stars may be more likely to remain ice-free than planets around hotter stars.

Hunting For Exoplanets
2013-07-19 10:34:45

The hunt is on for planets that, like Earth, have the conditions necessary for life to survive on their surfaces. But what exactly are scientists looking for? Earlier this week, NASA officials shed a little light on precisely what conditions they are seeking on worlds located beyond our solar system.

UK Launches SETI Network
2013-07-06 04:47:37

To promote academic research in the UK relating to the Search for Extraterrestrial Intelligence (SETI), a new network has been launched. Academics from 11 institutions across the UK are being brought together by the UK SETI Research Network (UKSRN), whose Patron is the Royal Astronomer, Professor Martin Rees.

Wind And Clouds Play An Important Role In Hot Jupiter Atmospheres
2013-07-05 05:27:23

Astronomers studying eight exoplanets falling into the "hot-Jupiter" class suggest winds and clouds play an important role in the atmospheric make up of these exotic planets.

Curious Flips Observed In Tau Boo's Magnetic Cycle

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...
