A new mission designed to detect and analyze extrasolar planets could launch as early as 2016, experts at the NASA Jet Propulsion Laboratory (JPL), in Pasadena, California, announce. They also released a brief video explaining how the new spacecraft would carry out its studies. The spacecraft will be called the NAS... |

In a paper published in the April 12 issue of the top scientific journal Nature, experts propose a new explanation for how stars of moderate weight manage to shed more than half of their mass, as they reach the end of their burning cycle.
What researchers observed when surveying medium-weight stars was that the obje... |

A series of short video clips depicting the cloud cover above Jupiter indicates that an invisible wave is influencing the gas giant's atmosphere in a pattern similar to what planetary scientists have already observed here on Earth. The recently-found wave is influencing one of Jupiter's largest jet stream... |

During a planetary alignment that took place on January 6, 2008, researchers at the European Space Agency (ESA) conducted a series of investigations meant to determine whether Earth's magnetosphere is indeed essential for our survival here. They found out that this was indeed the case.
While scientists have be... |

Back in 2009, astronomers at the Center for Astrophysics (CfA) announced the discovery of an extrasolar planet that may have an atmosphere filled with water vapor. Now, a study demonstrates that indeed the super-Earth may contain water, despite its close proximity to its parent star.
The object is called GJ1214b, a... |

Officials at the American space agency say that Hubble's successor, the James Webb Space Telescope, will not launch before 2018. However, when it does take off, the instrument will allow us to search for small extrasolar planets around distant stars.
The observatory is being put together in order to unlock som... |

Astronomers say that they were recently able to identify an entirely new type of extrasolar planet, which resembles none of the types we've seen before. While smaller than Uranus, the celestial body is much larger than Earth, but is also covered in water, for the most part. In addition, its surface is covered by... |

Among astronomers, Saturn's largest moon Titan is primarily known for being the only object in the solar system other than Earth to have liquid chemicals on its surface. A group of investigators in the United States finally provides an explanation of where these chemicals originate. Both of Titan's poles ... |

When the dwarf planet 2007 OR10 was discovered four years ago, experts nicknamed it Snow White due to the fact that it has an icy surface. Now, investigators in the United States determined that the small trans-Neptunian object is also covered in a very thin film of methane.Astronomers based at the California Institu... |

Astronomers surveying the constellation Draco found an extrasolar planet orbiting the star GSC 03549-02811, some 750 light-years away. The thing that makes this exoplanet stand out from all the rest is the fact that it's the blackest (darkest) one ever discovered. Early measurements indicate that it reflects les... |

Officials at the American space agency announce that the next mission to Mars has successfully completed the Mission Critical Design Review (CDR), an important milestone in its development. NASA is currently building the Mars Atmosphere and Volatile EvolutioN (MAVEN) spacecraft, which it plans to launch to the Red Pl... |

University of Paris astronomers recently finished conducting a 3D simulation of the atmosphere surrounding the exoplanet Gliese 581d, which was determined to be potentially habitable in past investigations. The previous work was carried out by the same team.
The extrasolar plant is located in a star system surrou... |

Scientists have recently determined that the atmosphere surrounding the dwarf planet Pluto is poisonous and toxic for humans. Apparently, it contains the dangerous gas carbon monoxide, the same that causes asphyxiation in humans who get trapped in fires.The investigation also managed to show that the space object... |

Experts have been trying for a long time to figure out precisely how is it that certain extrasolar planets, which orbit very close to their parent stars, are still able to hold on tho their atmosphere. A new study now provides a potential explanation for this. Of the more than 520 exoplanets discovered thus far, astr... |

Astronomers have produced the first detailed study showing some of the composition and structure of the exoplanet WASP-17b, which has gained notoriety after experts learned that it orbits its parent star backwards, in what is called a retrograde orbit. The peculiar extrasolar planet was announced back in August 2009.... |

A team of astronomers has recently proposed the use of a new criterion for determining what is going on in post main sequence stars. This new piece of data that needs to be considered is extremely relevant for experts in the field, given that the science of stellar evolution is very complex. Generally, in science, ex... |

A team of astronomers investigating extrasolar planets has recently determined one of the main reasons why these celestial bodies have radii that are a lot larger than they should be. The fact that this class of exoplanets is “puffy” has been known for quite some time, but experts have until now been unab... |

It could be that our planet has a lot more in common with Saturn's largest moon Titan than experts first thought possible. In a new investigation, carried out by experts at the University of Colorado in Boulder (UCB), it was revealed that the thick haze which constituted Earth's primordial atmosphere was mo... |

Astronomers say that a large comet may have stricken the gas giant Neptune not two centuries ago. They base their statement on the fact that the atmosphere surrounding the planet is very rich in carbon monoxide, which had no way of appearing on the space object through natural processes. The findings were presented i... |

Researchers looking at the renowned exoplanet WASP-12b have recently determined that the celestial body doesn't have much to live. Its parent star, a Sun-class yellow dwarf, is currently engulfing matter from its atmosphere, and is also deforming the overall shape of the planet. The celestial object already look... |
