An international collaboration of investigators says it has recently developed a new explanation for how stars known as brown dwarfs form. These objects sometimes blur the difference between very large gas giants and small stars, so explaining how they appear and why has been very difficult.
Astronomers have been tr... |

Recent astronomical observations found a cosmic phenomenon that shatters previous records for the lowest stellar temperature at which radio waves can be produced. Researchers were able to find flaring radio emissions coming from an ultra-cool, brown dwarf-class star.
Brown dwarfs are often referred to as failed star... |

Recent studies conducted at Jupiter indicate that the massive gas giant's core has been dissolving. They also indicate that the core may not be made up of rock or other solid chemicals, and that it may not contain layers at all. These data could help explain a lot of aspects experts found on CoRoT-20b.
The latt... |

While analyzing several hundred confirmed extrasolar planets, astronomers found that gas giants seem to prefer orbiting their parent stars in specific orbits, while leaving others entirely unoccupied. A new study now provides an answer to this mystery.
Jupiter- or Saturn-like exoplanets occupy these preferred regio... |

With each new image the NASA Cassini orbiter sends back, I appreciate the spacecraft more and more. For almost 8 years now, the probe has been conducting various experiments around Saturn, its rings and it moons, and the latest view it captured of Dione proves its worth yet again.

The NASA Kepler Telescope discovered two extrasolar planets, called KOI 55.01 and KOI 55.02, which orbit in very close orbit around their star, a hot B subdwarf. What is remarkable about these findings is that the stellar object passed its red giant phase.
This means that the star at one point began swelling up, sw... |

The largest and heaviest planet in our solar system is apparently well on its way to destroying its own core, a complex set of analyses has revealed recently. The most interesting implication of the new work is that the largest gas giant extrasolar planets may not have a core at all. Analyzing what goes on on Jupiter... |

A new set of computer simulations has revealed that the solar system may have contained an additional planet when it first developed, an object that was extremely massive by the look of things. The space body must have been ejected a long time ago, the team adds. Certain interpretations of the new model even indicate... |

According to the conclusions of a new astronomical study, it would appear that many star systems eject potentially-habitable exoplanets from their inner regions. This happens as the systems are still in their infancy, due to interactions between various objects in orbit around the same star.In this respect, it could ... |

The gas giant Neptune has finally completed its first orbit around the Sun since it was first discovered. The planet was observed on the night of September 23-24, 1846, and its first document orbit concluded yesterday, July 11, 2011, after 165 years. Neptune is the eighth and farthest planet from the Sun, and its com... |

In mid-December 2010, astronomers reported the development of a massive storm in the atmosphere of the gas giant Saturn, one of the largest planets in our solar system. The atmospheric structure has since grown to impressive size, reaching a diameter more than ten times that of Earth's.Last year, the beginning o... |

Astronomers say that they were recently able to confirm the existence of two Jupiter-class exoplanets in orbit around a pair of stars called a binary system.

One of the things that has remained the same about exoplanetary studies is the fact that astronomers always assume that a planet's orbit has remained the same for a long time. In most cases, this really happened, but in other instance it's far from it, scientists say. Recent studies on the influence gas gia... |

While a temperature of about 35,000 degrees Fahrenheit may seem a bit hot to most of us, physicists would consider it just warm. Within it, they say, resides warm dense matter, a type of matter that has been brought up to a high temperature, but not high enough to start undergoing nuclear fusion. One place where this... |
