  Washington, DC (SPX) Feb 27, 2018 A team of astronomers led by Carnegie's Meredith MacGregor and Alycia Weinberger detected a massive stellar flare--an energetic explosion of radiation--from the closest star to our own Sun, Proxima Centauri, which occurred last March. This finding, published in Astrophysical Journal Letters, raises questions about the habitability of our Solar System's nearest exoplanetary neighbor, Proxima b, which orbits Proxima Centauri. MacGregor, Weinberger and their colleagues--the Harvard-Smithsonian Center ... read more |

On second thought, the Moon's water may be widespread and immobileGreenbelt 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 ... more  
Beaming with the light of millions of sunsPasadena CA (SPX) Feb 27, 2018 In the 1980s, researchers began discovering extremely bright sources of X-rays in the outer portions of galaxies, away from the supermassive black holes that dominate their centers. At first, resear ... more

NASA's New Horizons spacecraft recently turned its telescopic camera toward a field of stars, snapped an image - and made history.
The routine calibration frame of the "Wishing Well" galactic open star cluster, made by the Long Range Reconnaissance Imager (LORRI) on Dec. 5, was taken when New Horizons was 3.79 billion miles (6.12 billion kilometers, or 40.9 astronomical units) from Earth - ... more |

Jupiter's icy moon Europa is a major target of astrobiology research in light of the possibility that it offers a habitable environment in the Solar System. Under its ice crust, estimated to be 10 km thick, is an ocean of liquid water of over 100 km deep. A huge source of energy deriving from gravitational interaction with Jupiter keeps this water warm.
Theoretical research to evaluate the ... more |

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 |
