The Gaia space probe on Monday unveiled its latest discoveries in its quest to map the Milky Way in unprecedented detail, surveying nearly two million stars and revealing mysterious “starquakes” which sweep across the fiery giants like vast tsunamis.
The mission’s third data set, which was released to eagerly waiting astronomers around the world at 1000 GMT, “revolutionises our understanding of the galaxy,” the European Space Agency (ESA) said.
ESA Director-General Josef Aschbacher told a press conference that it was “a fantastic day for astronomy” because the data “will open the floodgates for new science, for new findings of our universe, of our Milky Way”.
