  Washington DC (SPX) Feb 21, 2018 Tides on Earth have a far-reaching influence, including disturbing satellites' measurements by affecting their motion. This disturbance can be studied using a model for the gravitational potential of the Earth, taking into account the fact that Earth's shape is not spherical. The LAser RElativity Satellite (LARES), is the best ever relevant test particle to move in the Earth's gravitational field. In a new study published in EPJ Plus, LARES proves its efficiency for high-precision probing of Gener ... read more |

 Montreal, Canada (SPX) Feb 21, 2018 
Thanks to data collected by NASA's Chandra X-ray telescope on galaxies up to 3.5 billion light-years away from Earth, an international team of astrophysicists was able to detect what is likely to be the most massive black holes ever discovered in the universe. The team's calculations showed that these "ultramassive" black holes are growing faster than the stars in their respective galaxies.
