  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 state. "The Moon goes around the Earth, but its orbit is inclined by about five degrees with respect to th ... read 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 |

 Hannover, Germany (SPX) Dec 17, 2018 
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 |
