 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 |

 Beijing (XNA) Dec 13, 2018 
China's Chang'e-4 probe decelerated and entered the lunar orbit Wednesday, completing a vital step on its way to make the first-ever soft landing on the far side of the moon, the China National Space Administration (CNSA) announced.
After flying about 110 hours from earth, an engine on the probe was ignited when it was 129 km above the surface of the moon, in line with instructions sent fr ... more |

 Washington (AFP) Dec 21, 2018 
The United States has charged two Chinese men it says hacked the computer systems of companies and government agencies in a dozen countries, in what Washington says was a wide-reaching state-backed campaign of cyber-espionage.
NASA and the US Navy were among those allegedly targeted in a programme the US Justice Department said also hit a major bank, telecom companies and healthcare provider ... 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 |
