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).
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.
1,300,000 ly (400,000 pc) [1] H I region. Spiral nebula surrounding NGC 262, which is one of the largest known galaxies . Leo Ring. 650,000 ly (200,000 pc) [2] HVC. A large ring of cold gas that formed from a collision of two galaxies. [3] Magellanic Stream.
The Milky Way [c] is the galaxy that includes the Solar System, with the name describing the galaxy's appearance from Earth: a hazy band of light seen in the night sky formed from stars that cannot be individually distinguished by the naked eye.
FormGen Inc. found that user-generated maps were derivative works of the original game. In Sega v. Accolade , the 9th Circuit held that making copies in the course of reverse engineering is a fair use, when it is the only way to get access to the "ideas and functional elements" in the copyrighted code, and when "there is a legitimate reason for ...
Galaxy. NGC 4414, a typical spiral galaxy in the constellation Coma Berenices, is about 55,000 light-years in diameter and approximately 60 million light-years from Earth. A galaxy is a system of stars, stellar remnants, interstellar gas, dust, and dark matter bound together by gravity. [1] [2] The word is derived from the Greek galaxias ...
The rotation curve of a disc galaxy (also called a velocity curve) is a plot of the orbital speeds of visible stars or gas in that galaxy versus their radial distance from that galaxy's centre. It is typically rendered graphically as a plot, and the data observed from each side of a spiral galaxy are generally asymmetric, so that data from each ...
HD1 is a proposed high-redshift galaxy, which is considered (as of April 2022) to be one of the earliest and most distant known galaxies yet identified in the observable universe. The galaxy, with an estimated redshift of approximately z = 13.27, is seen as it was about 324 million years after the Big Bang , which was 13.787 billion years ago . [6]
