All-sky map of our galaxy, the Milky Way, and its neighbouring galaxies made from observations of the European Space Agency's Gaia spacecraft. Data from more than 1.8 billion stars were used to create this map. The map shows the density of stars, with brighter regions indicating denser concentrations of stars and darker regions areas where there are fewer stars. The Galactic Plane of the Milky Way is seen across centre. Pointing downwards from the Galactic plane is the Sagittarius satellite dwarf galaxy. The two bright areas at lower right are the dwarf galaxies the Large and Small Magellanic Clouds. At lower left is the spiral Andromeda galaxy (M31), with its satellite the Triangulum galaxy (M33) below it. Dark stripes and curved structures within the image are scanning artefacts that will be filled in as Gaia collects more data.
