Gaia
SPACE TELESCOPE · the galaxy mapper
The telescope that measured the Milky Way. Gaia charted the positions, distances and motions of almost two billion stars with mind bending precision, like measuring a coin on the Moon from Earth. Its star map lets astronomers run the galaxy backwards and forwards in time, revealing how the Milky Way formed and where its stars are headed.
