Electronic Arts Cancels ‘Gaia’ Game After Years in Development
Video game publisher Electronic Arts has canceled a game that was in development at its Montreal office for nearly six years, Bloomberg reported Thursday, citing people familiar with the matter. From a report: The game, code named Gaia, was first hinted at in 2015, but was never officially announced or given a title. Since then, EA executives have released a drip…

Binary stars are all around us, new map of solar neighborhood shows
The latest star data from the Gaia space observatory has for the first time allowed astronomers to generate a massive 3-D atlas of widely separated binary stars within about 3,000 light years of Earth—1.3 million of them. Source: https://phys.org/news/2021-02-binary-stars-solar-neighborhood.html…
Research reveals stellar kinematics of the galactic disc
By using a sample of 118945 red giant branch (RGB) stars from the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) and Gaia, Dr. Wu Yaqian from the National Astronomical Observatories of the Chinese Academy of Sciences (NAOC) investigated the stellar kinematics of the galactic disc in 7 Source: https://phys.org/news/2021-02-reveals-stellar-kinematics-galactic-disc.html…

New and rare direct image of a brown dwarf
Astronomers have obtained one of the best images yet of a brown dwarf, an object in a mass range midway between stars and planets. This brown dwarf – called HD 33632 Ab – lies 86 light-years from our sun. Source: https://earthsky.org/space/new-brown-dwarf-direct-image-hd-33632-ab…
Chinese astronomers discover 591 high-velocity stars with LAMOST and Gaia
A research team, led by astronomers from National Astronomical Observatories of Chinese Academy of Sciences (NAOC), has discovered 591 high velocity stars based on data from the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) and Gaia, and 43 of them can even escape from the Galaxy.
