  College Park MD (SPX) Feb 01, 2019 Apollo 17 astronauts drove a moon buggy across the lunar surface in 1972, measuring subtle changes in gravitational pull with an instrument called a gravimeter. Although there are no astronauts on Mars yet, a group of clever researchers here on Earth realized there is a buggy there - and it has just the right tools for similar experiments. In a research paper published January 31, 2019 in the journal Science, the researchers detail how they repurposed data from navigational sensors aboard NASA's C ... read more |

 Beijing (XNA) Feb 01, 2019 
China's Chang'e-4 probe, having made the first-ever soft landing on moon's far side, found that the temperature of the lunar surface dropped to as low as minus 190 degrees centigrade, colder than expected.

A large volcanic event was detected on Jupiter's moon Io using Jovian sodium nebula brightness variation, a new paper in Astrophysical Journal Letters said.
"These results highlight the growing body of evidence that the traditional way of monitoring Io's volcanism - by looking for temperature changes on its surface caused by hot lava - is not able to reliably find these large gas release e ... 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 |

 Vienna, Austria (SPX) Feb 01, 2019 
According to one of the most fundamental principles in physics, an observer on a moving train uses the same laws to describe a ball on the platform as an observer standing on the platform - physical laws are independent on the choice of a reference frame. Reference frames such as the train and the platform are physical systems and ultimately follow quantum-mechanical rules.
They can be, fo ... more |

We know far less about the Earth's oceans than we do about the surface of the moon or Mars. The sea floor is carved with expansive canyons, towering seamounts, deep trenches, and sheer cliffs, most of which are considered too dangerous or inaccessible for autonomous underwater vehicles (AUV) to navigate.
But what if the reward for traversing such places was worth the risk?
