  Greenbelt MD (SPX) Jul 31, 2018 Science fiction writers have long featured terraforming, the process of creating an Earth-like or habitable environment on another planet, in their stories. Scientists themselves have proposed terraforming to enable the long-term colonization of Mars. A solution common to both groups is to release carbon dioxide gas trapped in the Martian surface to thicken the atmosphere and act as a blanket to warm the planet. However, Mars does not retain enough carbon dioxide that could practically be put back ... read more |

 Pasadena CA (JPL) Jul 30, 2018 
The International Space Station is officially home to the coolest experiment in space.
NASA's Cold Atom Laboratory (CAL) was installed in the station's U.S. science lab in late May and is now producing clouds of ultracold atoms known as Bose-Einstein condensates. These "BECs" reach temperatures just above absolute zero, the point at which atoms should theoretically stop moving entirely. Th ... more |

 Beijing (XNA) Jul 23, 2018 
China is developing a space vehicle to help transport orbiting satellites that have run out of fuel, Science and Technology Daily reported Thursday.
Fuel is a key factor limiting the life of satellites. Most satellites function for years after entering orbit, but eventually, they have to end their missions and burn up into the atmosphere due to fuel exhaustion.
The vehicle is being d ... more |

With its dark, heavily cratered surface interrupted by tantalizing bright spots, Ceres may not remind you of our home planet Earth at first glance. The dwarf planet, which orbits the Sun in the vast asteroid belt between Mars and Jupiter, is also far smaller than Earth (in both mass and diameter). With its frigid temperature and lack of atmosphere, we're pretty sure Ceres can't support life as w ... more |

When two Sun-like stars collide, the result can be a spectacular explosion and the formation of an entirely new star. One such event was seen from Earth in 1670. It appeared to observers as a bright, red "new star."
Though initially visible with the naked eye, this burst of cosmic light quickly faded and now requires powerful telescopes to see the remains of this merger: a dim central star ... more |
