One of the most surprising discoveries Gaia was unwittingly and without being the focus of her main mission to detect stellar earthquakes or “stellar earthquakes”, which consist of small movements recorded on the surface of a star Change its shape and can be made New insights into the inner workings of these distant suns. Map of the Milky Way, photographed by the European Space Agency This data set has become Largest catalog so far From binary stars, thousands of objects in the Solar System, such as asteroids and the moons of planets, to the millions of galaxies and quasars that are outside the Milky Way.
#Radial velocity astrometry update
This week, The European Space Agency has released a new update of data collected by Gaia in the past three years, after it has observed 10 million stars and space objects, Which led to the publication of many scientific papers about some of the discoveries that were made. Scientists claim that The mission aims to build the largest and most accurate 3D spatial catalog ever created for the visible universe, With nearly two billion astronomical objects, most of them stars, but also planets, comets, asteroids and quasars, among other fascinating things from the vastness of space. In 2013 The European Space Agency (ESA) has launched a unique space mission: Gaia Space Observatory, A spacecraft specifically designed for astrometry – the science of measuring the positions, distances and motions of stars With precision never seen before. Gaia aims to build the largest and most accurate 3D spatial catalog ever created for the observed universe / ship: ESA / ATG medialab / Milky Way: ESA / Gaia / DPAC / IGO / A.
