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.
This is a list of satellite map images with missing or unclear data. Some locations on free, publicly viewable satellite map services have such issues due to having been intentionally digitally obscured or blurred for various reasons of this. [1] For example, Westchester County, New York asked Google to blur potential terrorism targets (such as ...
Gaia. (spacecraft) 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, [5] [6] and the positions of exoplanets by measuring attributes about the stars ...
The Large Magellanic Cloud (LMC) is a dwarf galaxy and satellite galaxy of the Milky Way. At a distance of around 50 kiloparsecs (163,000 light-years), the LMC is the second- or third-closest galaxy to the Milky Way, after the Sagittarius Dwarf Spheroidal (c. 16 kiloparsecs (52,000 light-years) away) and the possible dwarf irregular galaxy called the Canis Major Overdensity.
Orion Arm. The Orion Arm, also known as the Orion–Cygnus Arm, is a minor spiral arm within the Milky Way Galaxy spanning 3,500 light-years (1,100 parsecs) in width and extending roughly 10,000 light-years (3,100 parsecs) in length. [2] This galactic structure encompasses the Solar System, including Earth.
Google Earth is a computer program that renders a 3D representation of Earth based primarily on satellite imagery. The program maps the Earth by superimposing satellite images, aerial photography, and GIS data onto a 3D globe, allowing users to see cities and landscapes from various angles. Users can explore the globe by entering addresses and ...
Group of at least 80 galaxies of which the Milky Way is a part. Dominated by Andromeda (the largest), the Milky Way and Triangulum; the remainder are dwarf galaxies. Local Sheet: 7 Mpc 2.16×10 20: 20.33: Group of galaxies including the Local Group moving at the same relative velocity towards the Virgo Cluster and away from the Local Void.
The Milky Way started out small and grew in size as it merged with other galaxies, gaining stars as well as hydrogen to form more stars. Each galaxy has hydrogen gas that aids in the birth of stars.
