  Bern, Switzerland (SPX) Feb 22, 2017 TRAPPIST-1 is the name of the small, ultracool star that is the new hot topic in astronomy and the search for life outside our solar system. Observing the star with telescopes from the ground and space during an extensive campaign, an international team found that there are at least seven terrestrial planets around TRAPPIST-1. Their temperatures are low enough to make possible liquid water on the surfaces, as the researchers report in the journal Nature. "Looking for life elsewhere, this system is ... read more |

The demand for raw materials is rising continuously, forcing mining companies to use lower-grade ores and to explore at greater depths. This could lead to a decline in production in the coming decades.

Our Galaxy's gravitational field limits the accuracy of astrometric observations of distant objects. This is most clearly appeared for objects that are visually located behind the central regions of the Galaxy and the Galactic plane, where the deviation can be up to several dozen microarcseconds.

This means ... more New method uses heat flow to levitate variety of objects Increasing the sensitivity of next-generation gravitational wave detectors New laser technology from Hannover enables more sensitive gravitational-wave detectors |
