A new discovery about our galaxy arrives from the Gaia space observatory. The European Space Agency (ESA) has in fact published a new release of data: from the largest catalog ever compiled, which contains almost two billion stars, a mosaic of great scientific value takes shape.
The ESA mission, in fact, not only observed and traced the orbits of hundreds of millions of luminous dots in the dark of the night, but its vision proved to be sharp enough to ‘see’ the earthquakes that shake the stellar surface, to give the hunting for asteroids in our solar system, even spying on distant quasars and galaxies. Results that will be useful to a large part of the scientific community that studies the evolution of the Cosmos, from our neighborhood to the most remote distances: “It is a gold mine – underlines Antonella Vallerani, INAF astrophysicist at the Padua Observatory and deputy coordinator of the of the Gaia Data Processing and Analysis Consortium – with this third data release we expect sensational scientific results “.
The mission sees a strong participation of the Italian Space Agency (ASI) and the National Institute of Astrophysics (INAF).
