Astronomers now propose that Mercury may have been set on its weird orbit by an asteroid impact that occurred a long time ago. The idea came to scientists after noticing that our solar system's innermost planet was not tidally-locked to the Sun. Such a state can be seen on the Moon, which always keeps the same... |

For thousands of years, space has been a mystery. Even from ancient times, humanity has been interested in viewing, exploring and understanding the stars. But in order to do this, we had to go through a lot of scientific evolution. Nowadays, we have telescopes and other sophisticated equipment that can help us v... |

Yesterday, March 13, Illinois' Senate passed a bill that re-instated Pluto to a full planetary status, despite the fact that the celestial body lost an “election” with the General Assembly of the International Astronomical Union (IAU) some three years ago, in which its classification was changed to t... |

It appears that dangerous neighborhoods are not only a problem down here, on Earth, but instead cosmic bodies face such difficulties as well. NASA's Spitzer Space Telescope, seeing in infrared, has managed to capture an interesting phenomenon going on near a group of large stars. The image depicts an apocalyptic... |

There seems to be a constant rush as of late to demonstrate that what we used to know and treat as a given is wrong. Evolving technology and the increased amount of accurate scientific data provide more insight on many of these aspects that were not thoroughly investigated so far. As such, it appears that the prevale... |

Two years ago, Alice Quillen, an astronomer at the University of Rochester, estimated that a planet of a specific size is revolving in a precise orbit in the dust disk surrounding the Formalhaut star. A month ago, the Hubble Space Telescope took a very accurate image of the region, indicating that such a planet exist... |

The Two Micron All Sky Survey (2MASS) initiative performed by NASA's Infrared Processing and Analysis Center found what was thought to be a single, common brown dwarf planet, which was called 2M 0939, short for 2MASS J09393548-2448279. There was nothing special about it and not much attention was paid to it &nda... |

Assuming that Drake's equation would eventually proven right, and that there might be aliens out there (somewhere), and even that they are at least as smart as (we think) we are, the question still remains – What are the odds that we actually comprehend that we've stumbled upon a proof of alien intell... |

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.

Astronomy has gone a long way since the telescope was invented, and this device allows today's scientists to detect and deduce the presence of large planets outside our solar system. Still, the limited technology we have restrains the possibilities of finding smaller, Earth-like planets which may actually be mor... |

It seems that once started, the exoplanet direct observation process is quickly becoming a regular one, given the discovery of such an object.

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... |

The relentless search for new life-hosting planets has received a new boost from a recently-found star system located close to ours in astronomical terms. It looks a lot like our own did, back in the time life appeared on Earth, but a planet that would actually be appropriately placed is yet to be found. The system i... |

So far, our astronomers have managed to discover about 300 extrasolar planets, the majority of which they named “Hot Jupiters,” since they resemble the planet of our solar system pretty much in size and composition. The main difference, though, is that the alien worlds are much closer to their star than ... |

It's a known fact that the Sun will reach a point where it burns its hydrogen and will start swelling as it gets warmer, transforming into a red giant, and that all this will occur in approximately 5 billion years. But first, in about 1.1 billion years, it will become 11% brighter, lifting the Earth's aver... |

More and more scientists seem to be embracing the idea according to which extrasolar planets (planets from outside our solar system) with an oval orbit would provide enough heat in order to spark or sustain life on their surface. These planets would still have to be inside the “habitable zone” around thei... |

Astronomers still have trouble establishing once and for all the number of planets our system is comprised of.

There is no reason why other rocky planets in the universe should not be able to support life, but a considerable amount of time will pass before a planet such as our own is found in the galaxy, mostly because of its relatively small size.

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... |
