 Saitami, Japan (SPX) Jan 01, 2019 
Using observations from the ALMA radio observatory in Chile, researchers have observed, for the first time, a warped disk around an infant protostar that formed just several tens of thousands of years ago. This implies that the misalignment of planetary orbits in many planetary systems - including our own - may be caused by distortions in the planet-forming disk early in their existence.

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 |

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 |
