A new study conducted using the NASA Spitzer Space Telescope observed L1157, a stellar nursery located about 800 light-years away from Earth. The investigation was finally able to determine why the area contains such large amounts of water and ammonia.

Astronomers recently conducted a series of studies meant to provide additional insights into the nature of the Southern Equatorial Belt on Jupiter. The formation disappeared a year ago, and is currently making itself visible again. Planetary scientists are very interested in learning why the atmospheric structure is ... |

In a groundbreaking new study, researchers have shown that the earliest traces of ammonia on our planet may have been brought here by meteorites billions of years ago. One of the most important ingredients for life on Earth may therefore have an extraterrestrial origin. The new conclusions are based on the chemical a... |

After taking into account the progress made during the first two spacewalks destined to repair the broken ammonia pump on the International Space Station (ISS), NASA experts established that four excursions in space will be necessary to complete the job. Engineers and mission planners say that there is no other, fast... |

Officials at the American space agency announce that the emergency spacewalk they planned for the astronauts aboard the International Space Station (ISS) has been bumped to Friday, August 6. Initially, they said that the extra-vehicular activity (EVA) will take place on Thursday, but the new delay is prompted by more... |

On Tuesday, while conducting the last spacewalk of the STS-131 mission to the International Space Station (ISS), two astronauts noticed that one of the valves in a newly-installed ammonia tank was jammed. The malfunction is fairly serious, given the fact that the ammonia tank contains the coolant for the orbital faci... |

As we were reporting a couple of days ago, the new module on the International Space Station (ISS), Tranquility, was “unofficially” opened by the joint crew currently aboard the orbital lab. In a late Saturday spacewalk, or extra-vehicular activity (EVA), NASA astronauts Robert Behnken and Nicholas Patric... |

Over the years, as scientists browsed satellite data or took to the field, numerous comet and asteroid impact sites have been discovered on the surface of our small planet. But experts believe that many more may still be out there, unknown to Science. Finding them is very important, because they could provide a windo... |

We have recently written a piece on the Early Ammonia Servicer (EAS) device that NASA astronaut Clayton Anderson threw overboard on July 23rd, 2007. Although it was not a small object, no official announcement was made so as to warn the public of the danger it might pose upon entering the atmosphere, possibly becaus... |

More than one year ago, on July 23rd, 2007, NASA astronaut Clayton Anderson, a flight engineer on Expedition 15, tossed away into space a large piece of junk. During a spacewalk mission, with the help of the station's robotic arm built in Canada, he disposed of a useless tank, previously filled with ammonia cool... |
