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
PIX4630235: Artist's view of the solar system - Solar system artwork - Artist's view of the solar system. Planets are represented in order of proximity to the sun. From left to right: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune. A comet and a galaxy are also represented. Solar system artwork. The planets are shown from the nearest planet of the Sun, Mercury (left), to the farthest (right), Neptune. A comet and a galaxy are shown. Since August 2006, Pluto is no more a planet but a dwarf planet called 134340 Pluto / Bridgeman Images
PIX4583884: Asteroides threaten the Earth - Artist view - Asteroids threatening the Earth - Artist view - Title: Space Situational Awareness - Near Earth Objects Picture caption: The SSA-NEO system is based on syndicating and federating observation and tracking data provided by a large number of European and international sources. The key components include: -Observatories and astronomers with telescopes of various sizes, both professional and amateur -A central SSA-NEO data centre, the 'Small Bodies Data Centre', which uses astrometric measurements collected by the Minor Planet Center (USA) -An analysis capability to predict possible impact locations and assess dangers -Analyses related to risk mitigation, including the possible deflection of an asteroid -A system for issuing warnings and alerts to civil authorities in Europe Data on NeOS are collected from telescopes and radar systems worldwide. Each of these submit observations to the Minor Planet Center (MPC), operated by the International Astronomical Union (IAU) at Cambridge, Massachusetts, USA, which acts as a central clearing house for asteroid and comet observations. The measurements collected there are retrieved by the European Small Bodies Data Centre; orbits and miss distances are computed. In case of high-risk impact predictions, the data will be cross-checked with NASA's SENTRY system, operated by the Jet Propulsion Laboratory (JPL), California, before issuing alerts / 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
