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).
An all-sky view of stars in the Milky Way and neighbouring galaxies, based on the first year of observations by Gaia, from July 2014 to September 2015. Map shows the density of stars observed by Gaia in each portion of the sky. Brighter regions indicate denser concentrations of stars, while darker regions correspond to patches of the sky where ...
Gaia is a space observatory of the European Space Agency (ESA) that was launched in 2013 and is planned to operate until March 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.

The limits of observation as visualized by the Milky Way's star density map. Source: Gaia spacecraft's 2021 data release. Many projects have attempted to bridge the gap in knowledge caused by the Zone of Avoidance. The dust and gas in the Milky Way cause extinction at optical wavelengths, and foreground stars can be confused with background ...
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. [97] [98] Data from Gaia has
A new "Tycho catalog" drew together a database of 1,058,332 stars to within 20-30 mas (milliarcseconds). Additional catalogues were compiled for the 23,882 double and multiple stars and 11,597 variable stars also analyzed during the Hipparcos mission. [11] In 2013, the Gaia satellite was launched and improved the accuracy of Hipparcos. [12]
The Mount Stony Brook Observatory is an astronomical observatory operated by Stony Brook University in Stony Brook, New York. It is located on the roof of the Earth and Space Sciences Building. The dome contains a Meade 14" Maksutov–Cassegrain telescope and SBIG (SBIG-STL1001e) imaging equipment. The telescope is used for teaching ...
The pixelisation related to the H=4, K=3 projection has become widely used in cosmology for storing and manipulating maps of the cosmic microwave background. Gaia mission uses HEALPix as the basis for source identification. [9] An alternative hierarchical grid is the Hierarchical Triangular Mesh (HTM).
