  Paris (AFP) Feb 22, 2017 Researchers announced Wednesday the stunning discovery of seven Earth-like planets orbiting a small star in our galaxy, opening up the most promising hunting ground so far for life beyond the Solar System. All seven roughly match the size and mass of our own planet and are almost certainly rocky, and three are perfectly perched to harbour life-nurturing oceans of water, they reported in the journal Nature. Most critically, their proximity to Earth and the dimness of their red dwarf star, called ... read more |

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 |
