  Washington (UPI) Mar 1, 2018 A small asteroid will pass within 70,000 miles of Earth's surface on Friday - a close but safe encounter. They flyby will be streamed live online by the Virtual Telescope Project. Asteroid 2018 DV1 will reach its closest point to Earth at approximately 12:54 p.m. ET. The flyby will mark the 18th time an asteroid has passed between Earth and the moon in 2018. It's possible others have passed without being spotted by astronomers. Scientists only just identified 2018 DV1 on Monday. ... read more |

 Paris (ESA) Feb 28, 2018 
Last year, ESA's Gaia mission helped astronomers make unique observations of Neptune's largest moon, Triton, as it passed in front of a distant star. This is a preview of the superb quality and versatility of the Gaia data that will be released in April.
When a small Solar System body such as a moon or an asteroid passes in front of a star and temporarily blocks its light, the occultation ... more |

 Pullman WA (SPX) Feb 27, 2018 
For the first time, researchers have seen life rebounding in the world's driest desert, demonstrating that it could also be lurking in the soils of Mars. Led by Washington State University planetary scientist Dirk Schulze-Makuch, an international team studied the driest corner of South America's Atacama Desert, where decades pass without any rain.
Scientists have long wondered whether micr ... more |

 Greenbelt MD (SPX) Feb 27, 2018 
A new analysis of data from two lunar missions finds evidence that the Moon's water is widely distributed across the surface and is not confined to a particular region or type of terrain. The water appears to be present day and night, though it's not necessarily easily accessible.
The findings could help researchers understand the origin of the Moon's water and how easy it would be to use ... more |
