What are stellar earthquakes that make stars move? The Gaia mission of the European Space Agency revealed the earthquakes that occur thousands of light years away. Argentine astronomers explain the scope of this space telescope and its discoveries. In 2013 the European Space Agency (ESA), launched a unique space mission: the Gaia space observatory, a spacecraft designed specifically for astrometry: the science that measures the positions, distances and motions of stars with a precision never seen before. Scientists say the mission aims to build the largest and most accurate 3D space catalog ever made of the observable universe, with a total of approximately two billion astronomical objects, mainly stars, but also planets, comets, asteroids and quasars, among other fascinating objects in the vastness of space. This week, ESA released a new update of data collected by Gaia in the last three years, after having observed 10 million stars and space objects, which led to the publication of s...
