Gaia ist ein Weltraumteleskop der Europäischen Weltraumorganisation (ESA), das den gesamten Himmel hochgenau dreidimensional optisch durchmustert. Es ist spezialisiert auf Objekte der Magnituden 3 bis 21, weshalb die hellsten Sterne am Nachthimmel wie Sirius oder Alpha Centauri nicht erfasst werden.
26. Apr. 2018 · „Die zweite Veröffentlichung der von Gaia gesammelten Daten stellen im Vergleich mit dem Gaia-Vorgänger Hipparcos einen wahnsinnigen Entwicklungssprung dar. Im Rahmen dieser ersten wissenschaftliche Weltraummission für Astrometrie hat der ESA-Satellit vor fast 30 Jahren etwa 118.000 Sterne vermessen“, sagt Anthony Brown von der Universität Leiden in den Niederlanden.
26 February 2019 ESA's Gaia satellite is on a mission: to map and characterise more than one billion of the stars in the Milky Way. Many of these stars reside in complex, eye-catching clusters scattered throughout our Galaxy and, by studying these stellar groupings, Gaia is revealing much about the formation and evolution of stars in our cosmic ...
Gaia overview. Status: In operation. A global space astrometry mission, Gaia is building the largest, most precise three-dimensional map of our Galaxy by surveying nearly two billion objects. Throughout the course of its mission, Gaia monitors each of its target stars about 14 times per year. It is precisely charting their positions, distances ...
The mission. Gaia is creating an extraordinarily precise three-dimensional map of more than a thousand million stars throughout our Milky Way galaxy and beyond, mapping their motions, luminosity, temperature and composition. This huge stellar census will provide the data needed to tackle an enormous range of important questions related to the ...
Gaia is a space observatory of the European Space Agency (ESA), launched in 2013 and expected to operate until 2025. The spacecraft is designed for astrometry: measuring the positions, distances and motions of stars with unprecedented precision, [5] [6] and the positions of exoplanets by measuring attributes about the stars they orbit such as their apparent magnitude and color. [7]
The Gaia Mission. Gaia relies on the proven principles of ESA's Hipparcos mission to help solve one of the most difficult yet deeply fundamental challenges in modern astronomy: the creation of an extraordinarily precise three-dimensional map of about one billion stars throughout our Galaxy and beyond. This massive stellar census provides the ...
