Gaia - NASA Science
2013年12月19日 · Gaia, the Global Astrometric Interferometer for Astrophysics, is a European Space Agency astronomical observatory mission. Its goal is to create the largest, most precise three-dimensional map of the Milky Way by surveying about 1% of the galaxy’s 100 billion stars.
Gaia sees strange stars in most detailed Milky Way survey to date
2022年6月13日 · Astronomers describe strange ‘starquakes’, stellar DNA, asymmetric motions and other fascinating insights in this most detailed Milky Way survey to date. Gaia is ESA’s mission to create the most accurate and complete multi-dimensional map of the Milky Way.
ESA Science & Technology - 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 ...
Gaia creates richest star map of our Galaxy – and beyond
2018年4月25日 · Gaia is an ESA mission to survey more than one billion stars in our Galaxy and its local neighbourhood in order to build the most precise 3D map of the Milky Way and answer questions about its structure, origin and evolution.
ESA - Gaia unravels the ancient threads of the Milky Way
2024年3月21日 · ESA’s Gaia space telescope has further disentangled the history of our galaxy, discovering two surprising streams of stars that formed and wove together over 12 billion years ago. The two streams, named Shakti and Shiva, helped form the infant Milky Way.
Gaia Makes Most Accurate 3D Map of the Milky Way Yet
2020年12月3日 · Astronomers have released a new, extremely detailed three-dimensional census of our Milky Way galaxy. Data from more than 1.8 billion stars have been used to create this map of the entire sky. Brighter regions represent denser concentrations of bright stars, while darker regions correspond to patches of the sky where fewer and fainter stars are ...
New Maps of Milky Way Are Biggest and Best Yet
2022年6月22日 · Within minutes of the release, ESA unveiled updated three-dimensional maps of the Milky Way and unleashed a deluge of new information on the billions of stars around us—what they’re made of,...

Facts about Europe's star-mapping Gaia mission | Space
2022年6月13日 · How does Gaia study the Milky Way? Nestled in the Lagrange Point 2, some 930,000 (1.5 million kilometers) miles away from Earth, Gaia orbits the sun in synch with our planet.
ESA spacecraft creating '3D map of the Milky Way' to be shut down
2 天之前 · The European Space Agency’s (ESA) Gaia spacecraft will end its observations this week as it runs out of cold gas propellant. Gaia space telescope aimed to create an accurate and detailed 3D map of billions of stars in our galaxy and has flipped astronomers' understanding of the Milky Way on its head.. After more than a decade of mapping the stars and expanding our …
