Artificial brain helps Gaia catch speeding stars

Mon, 2017-06-26 08:00

With the help of software that mimics a human brain, ESA’s Gaia satellite spotted six stars zipping at high speed from the centre of our Galaxy to its outskirts. This could provide key information about some of the most obscure regions of the Milky Way.
