This satellite was the first French artificial satellite launched on 26 November 1965 by a Diamant-A rocket from Earth.

PIX4645992: GAIA satellite - Illustration - View of the European satellite GAIA against a milky lane background. The objective of the Gaia mission is to carry out the largest possible census of the stars of our Galaxy and to create a 3D map of a very precise 3D map. The satellite will determine the position, color and proper movement of a billion stars. Gaia was launched since Kourou on December 19, 2013. Artist's print of Gaia. Gaia is an ambitious mission to chart a three - dimensional map of our Galaxy, the Milky Way, in the process revealing the composition, formation and evolution of the Galaxy. Gaia will provide unprecedented positional and radial velocity measurements with the accuracies needed to produce a stereoscopic and kinematic census of about one billion stars in our Galaxy and throughout the Local Group. This amounts to about 1 per cent of the Galactic stellar population. Combined with astrophysical information for each star, provided by on - board multi - colour photometry, these data will have the precision necessary to quantify the early formation, and subsequent dynamical, chemical and star formation evolution of the Milky Way Galaxy. Additional scientific products include detection and orbital classification of tens of thousands of extra - solar planetary systems, a comprehensive survey of objects ranging from huge numbers of minor bodies in our Solar System, through galaxies in the nearby Universe, to some 500,000 remote quasars. It will also provide a number of stringent new tests of general relativity and cosmology. Gaia was launched from Europe's Spaceport in French Guiana on December 19, 2013 / Bridgeman Images
PIX4633329: Earth 200 million years ago - Artist's view - Early Jurassic Earth - Earth seen at the beginning of the Jurassic, about 200 million years ago. The western hemisphere is representative, the north is up. The Pangee has just split, forming Laurasia to the north and Gondwana to the south. This is how the western hemisphere of the Earth may have appeared 200 million years ago during the Early Jurassic period. North is at the top. During this period continental drift, driven by the massive forces of plate tectonics, had just begun to break the supercontinent of Pangea into Laurasia in the north and Gondwana in the south. In this image the nascent North American continent has just broken away from North Africa while South America and the rest of Africa remain joined as Gondwana. To the west in the global Panthalassa ocean are strips of land corresponding to the Wrangellia Terrane which later merged with western North America / Bridgeman Images
PIX4608398: Planetary system around Trappist-1 - Artist's impressions of the TRAPPIST-1 planetary system: Artist's view of extrasolar planets around the red dwarf star TRAPPIST-1. At least seven exoplanets the size of the Earth are orbiting this star 40 light years ago in the constellation Aquarius. All could contain water. This artist's impression shows several of the planets orbiting the ultra-cool red dwarf star TRAPPIST-1. New observations, when combined with very sophisticated analysis, have now yielded good estimates of the densities of all seven of the Earth-sized planets and suggest that they are rich in volatile materials, probably water / Bridgeman Images
