According to the conclusions of a new scientific study, it would appear that Sun-like stars around our galaxy harbor alien Earths very often. It is estimated that between 1-in-37 and 1-in-70 of them contain such extrasolar planets in their orbits. Yellow dwarf stars may therefore be the most suitable type of cosmic f... |

The international astronomical community is current in doubts whether a recently-found extrasolar planet actually exists, or whether it is simply a fluke in long-term calculations. If the body is indeed real, then many of our theories on how planets form around stars may need revising. The peculiar object was discove... |

The American space agency's Kepler Telescopes was one of our best bets at finding a rocky, Earth-like exoplanet around other stars. Its incredibly precise instruments were to ensure that this would happen seamlessly, but it would seem that it was precisely its scientific payload that now prevents it from actuall... |

It seems that researchers have reached the same conclusion we talked about in some of our articles published not long ago: the exoplanet discovery process, as fortuitous and science-boasting as it may be, does get old. A series of exoplanets have been discovered in the recent few months alone. Tragically, they seem t... |

At some point, 5 billion years from now, the Sun will begin to swell and will slowly engulf the first planets in its vicinity, including our own. But life would have been obliterated long before this process actually occurred. Still, this is not necessarily a scary scenario, since while scorching our planet, the Sun ... |

Discovering planets from outside our solar system by using the indirect radial velocity technique seems to have lost its novelty factor as of late, but it doesn't lower the merits and importance of adding to the growing number of exoplanets. The latest member of the exoplanet discoveries club, called OGLE2-TR-L9... |

Another planet has been discovered outside the boundaries of our solar system. A team of astronomers came upon the planet while performing observations with the Hobby-Eberly Telescope of McDonald Observatory in Texas. Actually, they did not observe the planet directly, but rather deduced it was there by using the rad... |

It seems that once started, the exoplanet direct observation process is quickly becoming a regular one, given the discovery of such an object. A group of astronomers from France, led by Anne-Marie Lagrange, used images from the Very Large Telescope in order to pinpoint the location of a planet supposed to be approxim... |

During a period a bit over a dozen years, planet hunters have come upon over 300 exoplanets, but they have done so by calculating light, speed or gravity changes of the stars they were thought to orbit. This time, two astronomer teams have managed to spot exoplanets directly, by means of actual photographs. Astronome... |

A new gas giant exoplanet roughly the size of Jupiter orbiting around a star similar to our Sun has been found by the CoRoT space telescope operated by the European Space Agency. The planet, dubbed CoRoT-Exo-4b, was discovered through a transit method, appears to complete an orbit around its star in about 9.2 days an... |

Until now, several hundred planets have been found orbiting around nearby stars while the number of moons remained at a constant zero. It's not that they're not there, it's just that we can't see them with today's technology. To put it even simpler, the smallest planet ever found was a terres... |

Only a few decades ago, astronomers weren't even sure if other solar systems aside ours exist in the universe. Since then, a couple of hundreds of solar systems have been discovered, mostly composed of gas giants. When trying to learn about other solar systems, astronomers often make analogies to our own. If our... |

The study of exoplanets and other solar systems is in high gear ever since the discovery of the first extrasolar planet back in 1996, finding new and interesting facts about solar systems formation processes. The same thing is available for an object orbiting a distant star, found nearly four years ago. The gas giant... |

A newly discovered exoplanet puzzles astronomers. Named XO-1b, the planet is the most massive found orbiting extremely close to its star, but it doesn't have a circular orbit, like most astronomers would have expected, but an elliptical one, which is very unusual, considering the short distance to its sun.Disco... |

Finding planets orbiting stars at great distances from our solar system is not an easy job, but there seem to be many of them out there, according to recent observations. And that's a great thing, since it's actually harder than finding a needle in space hay stack. It's more like looking for a firefl... |

Until now, scientists have used various techniques to detect more than 200 exoplanets. Most of these exoplanets are from five to 4,000 times more massive than Earth, and are either too hot, too cold or too much of a giant gas ball to be considered likely habitats for life. So far, no one has managed to capture an im... |
