Gaia’s First Sky Map

gaia-sky-map

Yesterday the European Space Agency released a sky map based on the first 14 months of data collected by the Gaia spacecraft, an astrometric observatory whose mission is to create a precise catalogue of astronomical objects’ position and relative motion. Several versions are available: annotated, unannotated, annotated with titles (above), unannotated with titles. The maps contain artifacts (curves and stripes) from Gaia’s scanning procedures, but they’ll improve as more data is added over the course of Gaia’s five-year mission.
