PARIS: Europe’s Gaia satellite has produced a “stunning” 3-D map, published Wednesday, of more than a billion stars in our Milky Way galaxy, complete with their distance from Earth, their colour, and their motion through space. The eagerly-anticipated catalogue was compiled from data gathered by Gaia on some 1.7 billion stars over 22 months in 2014-2016, from its unique vantage point in space about 1.5 million kilometres (930,000 miles) from Earth. “The dataset is very rich and we believe it will revolutionise astronomy and our understanding of the Milky Way,” Gaia’s scientific operations manager Uwe Lammers told AFP of the massive data release.
