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, Universität Heidelberg).
Initial Gaia Source List. The Initial Gaia Source List (IGSL) is a star catalogue of 1.2 billion objects created in support of the Gaia mission. The mission should have delivered a catalogue based entirely on its own data. For the first catalogue, Gaia DR1, a way was needed to be able to assign the observations to an object and to compare them ...
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, and the positions of exoplanets by measuring attributes about the stars they orbit such as their apparent magnitude and color.
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 ...
Gaia BH1. Gaia BH1 ( Gaia DR3 4373465352415301632) is a binary system consisting of a G-type main-sequence star and a likely stellar-mass black hole, located about 1,560 light-years (478 pc) away from the Solar System in the constellation of Ophiuchus. [4] As of May 2024, it is the nearest known system that astronomers are reasonably confident ...
Description Gaia’s first sky map, annotated.png. 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
English: Gaia, ESA’s billion-star surveyor, is detecting stars and measuring their properties in order to build up the most precise 3D map of the Milky Way. By accurately measuring the motion of each star, astronomers will be able to peer back in time to understand the Milky Way’s history, its evolution and its destiny.
Gould Belt. 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. [1] It contains many O- and B-type stars, and many of the nearest star-forming regions of the local Orion Arm, to which the Sun belongs.
English: PDF version: File:Galaxy Map Poster 1000pc.pdf. 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.
