  Washington (UPI) Dec 28, 2018 Mercury's poles are marked by large craters. Icy deposits hide inside. Now, scientists think they know how the ice got there. Researchers at the University of Maine modeled the glaciation process on the planet closest to the sun. Most of Mercury is rather hot. But a few of its polar craters remain in permanent shadow, allowing for temperature low enough to sustain ice deposits. The glaciers are thought to be less than 50 million years old and 165-feet thick in some places. Scienti ... read more |

 Laurel MD (SPX) Dec 27, 2018 
NASA's New Horizons spacecraft is set to fly by a distant "worldlet" 4 billion miles from the Sun in just six days, on New Year's Day 2019. The target, officially designated 2014 MU69, was nicknamed "Ultima Thule," a Latin phrase meaning "a place beyond the known world," after a public call for name recommendations. No spacecraft has ever explored such a distant world.
Ultima, as the flyby ... more |

 Warwick UK (SPX) Dec 24, 2018 
A massive stellar flare on a baby star has been spotted by University of Warwick astronomers, shedding light on the origins of potentially habitable exoplanets.
One of the largest ever seen on a star of its type, the huge explosion of energy and plasma is around 10,000 times bigger than the largest solar flare ever recorded from our own Sun.
The discovery is detailed in a paper for t ... more |

Mars atmospheric opacity (tau) over the rover site remains at a storm-free range around 1.0.
No signal from Opportunity has been heard since Sol 5111 (June 10, 2018). Opportunity likely experienced a low-power fault, a mission clock fault and an up-loss timer fault.
Since the loss of signal, the team has been listening for the rover over a broad range of times, frequencies and polari ... more |

 Edmonton, Canada (SPX) Dec 21, 2018 
New research from University of Alberta physicists provides the first-ever model of our Moon's rotational dynamics, taking into consideration its solid inner core. Their model helps to explain why, as seen from Earth, the Moon appears to wobble on its axis.
The answer, said physicist Mathieu Dumberry, lies in the complex geometry of the Moon's orbit, locked in what is known as a Cassini st ... more |

The detection of Einstein's gravitational waves relies on highly precise laser measurements of small length changes. The kilometer-size detectors of the international network (GEO600, LIGO, Virgo) are so sensitive that they are fundamentally limited by tiny quantum mechanical effects.
These cause a background noise which overlaps with gravitational-wave signals. This noise is always presen ... more |
