As expected, the Gliese 581 system did not disappoint and is now revealing the smallest planet outside our solar system, bringing the total number of planets found orbiting around the red dwarf star to three. When the star was first targeted by astronomers nearly two years ago, only a single planet was detected. The ... |

It may seem strange to some of us but, in fact, it is easier to identify a planet as having the characteristics of our own than actually finding a planet with a size comparable to Earth. For example, there are currently about 270 known exo-planets, of which only a handful have rocky surfaces. By studying light scatte... |

Brown dwarfs, or failed stars, are stellar bodies with masses 10 to 70 times higher than Jupiter's. Although, like all stars, they have the capability of initiating thermonuclear fusion reactions in their cores, their masses do not permit them to sustain these reactions for a very long time, unlike typical stars... |

The new exo-planet, dubbed GJ 436c, moves in an orbit around the star GJ 436, located in the Leo constellation, 30 light years away from Earth. Relying on the mass of the planet, scientists believe that it could be a rocky planet, about five times heavier than our own. The discovery was made by researchers from the U... |

The Wide Area Search for Planets international collaboration announced that it had found 10 new extra solar planets, by using of robotic camera systems, which survey solar systems other than our own, in the hope of understanding how planets are formed around stars. Astronomers are expected to detail their findings to... |

Orbiting its parent star from a distance of only 5.6 million kilometers, the HAT-P-7b is only the latest exo-planet discovered in our galaxy and, at the same time, the hottest planet ever found. HAT-P-7b was detected by an array of small telescopes owned by the HATNet project and is located about a thousand light ye... |

Another exo-planet found and yet another intriguing discovery! Astronomers reveal that an exo-planet detected back in 2005, located in a solar system in the Vulpecula constellation, 63 light-years away from Earth, has a methane-rich atmosphere. The planet dubbed HD 189733b is a gas giant relatively similar to Jupiter... |
