Dec 3, 2020 · The motion of stars in the outskirts of our galaxy hints at significant changes in the history of the Milky Way. This and other equally fascinating results come from a set of papers that demonstrate the quality of ESA's Gaia Early third Data Release (EDR3), which is …
ESA Science & Technology - 360° view of Gaia's sky
Sep 1, 2019 · Explore Gaia's all-sky view of our Milky Way Galaxy and neighbouring galaxies in 360 degrees. The map, based on measurements of nearly 1.7 billion stars, shows the total brightness and colour of stars observed by the ESA satellite in each portion of the sky between July 2014 and May 2016.
Gaia untangles the starry strings of the Milky Way
Aug 28, 2019 · Gaia was launched in 2013, and is on a mission to chart a three-dimensional map of our galaxy, pinpointing the locations, motions, and dynamics of roughly one percent of the stars within the Milky Way, along with additional information about many of these stars.
ESA Science & Technology - Gaia's first sky map - European Space …
Sep 14, 2016 · An all-sky view of stars in our Galaxy – the Milky Way – and neighbouring galaxies, based on the first year of observations from ESA's Gaia satellite, from July 2014 to September 2015. This map shows the density of stars observed by …
Galactic ghosts: Gaia uncovers major event in the formation of the ...
Oct 31, 2018 · ESA's Gaia mission has made a major breakthrough in unravelling the formation history of the Milky Way. Instead of forming alone, our Galaxy merged with another large galaxy early in its life, around 10 billion years ago.
Milky Way's warp caused by galactic collision, Gaia suggests
Mar 2, 2020 · Astronomers have pondered for years why our galaxy, the Milky Way, is warped. Data from ESA's star-mapping satellite Gaia suggest the distortion might be caused by an ongoing collision with another, smaller, galaxy, which sends ripples through the galactic disc like a rock thrown into water.
ESA Science & Technology - The Milky Way's Warp
Mar 2, 2020 · The structure of our galaxy, the Milky Way, with its warped galactic disc, where the majority of its hundreds of billions of stars reside. Data from ESA's star-observer Gaia recently proved that the disc's warp is precessing, essentially …
ESA Science & Technology - Gaia's surprising discoveries – Part 1 …
Apr 20, 2018 · An immediate surprise was the discovery of a large population of stars that orbit the Milky Way in the opposite direction to most stars. These `ghost rider’ stars probably came from a smaller galaxy that was cannibalized by the Milky Way.
ESA Science & Technology - Gaia's billion-star map hints at …
Sep 14, 2016 · Gaia is an ESA mission to survey one billion stars in our Galaxy and local galactic neighbourhood in order to build the most precise 3D map of the Milky Way and answer questions about its structure, origin and evolution.
