Gaia Sky is an open-source astronomy visualisation desktop and VR program with versions for Windows, Linux and macOS. It is created and developed by Toni Sagristà Sellés in the framework of ESA 's Gaia mission to create a billion-star multi-dimensional map of our Milky Way Galaxy , in the Gaia group of the Astronomisches Rechen-Institut (ZAH ...
On 30 August 2014, Gaia discovered its first supernova in another galaxy. On 3 July 2015, a map of the Milky Way by star density was released, based on data from the spacecraft. [61] As of August 2016, "more than 50 billion focal plane transits, 110 billion photometric observations and 9.4 billion spectroscopic observations have been ...
The Gaia Sausage or Gaia Enceladus is the remains of a dwarf galaxy (the Sausage Galaxy, or Gaia-Enceladus-Sausage, or Gaia-Sausage-Enceladus) that merged with the Milky Way about 8–11 billion years ago. At least eight globular clusters were added to the Milky Way along with 50 billion solar masses of stars, gas and dark matter. [1]
Today’s release, based on 22 months’ worth of data from ESA’s Gaia sky-mapping satellite, follows up on an initial version of the catalog that was released in 2016. This second release adds ...
English: An all-sky view of stars in 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 Gaia in each portion of the sky.
Map of stars cataloged by the Gaia release in 2021, displayed as density mesh in the diagram. The ESA spacecraft Gaia provides distance estimates by determining the parallax of a billion stars and is mapping the Milky Way with four planned releases of maps in 2016, 2018, 2021 and 2024. Data from Gaia has
The image appears in strips, each representing a sky mapper CCD (see this animation of how Gaia’s camera works). The image has been lightly processed to bring out the contrast of the bright stars and darker traces of gas and dust.
Map of the Solar Neighbourhood within 1000 parsecs. This map combines Gaia DR3 and Gaia EDR3 data to provide a detailed image of the solar neighbourhood out to 1000 parsecs. Includes OB star density isosurfaces, dust clouds, young and/or luminous star clusters and HII regions.
Mesh map of the inner Gould Belt created from Gaia observatory data. The Gould Belt is a local ring of stars in the Milky Way, tilted away from the galactic plane by about 16–20 degrees, first reported by John Herschel and Benjamin Gould in the 19th century.
English: PDF version: File:Galaxymap.com, map 100 parsecs (2022).pdf. Map of stars and star density structures within 100 parsecs. Map of the most intrinsically luminous stars within 100 parsecs from the Gaia Catalogue of Nearby Stars (based on Gaia EDR3).
