Our Gaia observatory has been mapping our galaxy since 2013, creating the most accurate and complete multi-dimensional map of the Milky Way. Today the third data set was released. This data release contains even more and improved information about almost 2 billion stars, Solar System objects and extragalactic sources. It also includes radial velocities for 33 million stars, a five-time increase compared to data release 2. Another novelty in this data set is the largest catalogue yet of binary st

We now have the most accurate 3D map of regions where stars are forming in our Milky Way, thanks to our Gaia spacecraft. ✨ This map is based on Gaia’s observations of 44 million ordinary stars and 87 O-type stars. (O-type stars are rare starts, they are young, massive and extremely bright and hot.) These star-forming regions are well-studied; many telescopes have captured stunning images of them. But now for the first time, we know what they look like in three dimensions and from an outside pers

This Spacecraft has scanned almost 2 billion stars. The GAIA spacecraft is an astrometric observatory launched by the European Space Agency (ESA) on December 19, 2013. Its mission is to create the most extensive and precise three-dimensional map of the Milky Way galaxy by surveying about 1% of the galaxy’s 100 billion stars. #esa #spacecraft #nasa | Secrets of Space
