This is a list of fictional galactic communities who are space-faring, in contact with one or more space-faring civilizations or are part of a larger government, coalition, republic, organization or alliance of two or more separate space-faring civilizations.
The FAA grounded Virgin Galactic's space planes before allowing a resumption of flights after some changes to procedures including reserving a larger volume of airspace. [80] On 14 October 2021, Virgin Galactic announced that an upgrade program for Unity and Eve would begin, delaying future commercial flights to mid 2022. This followed material ...
Galaxy Zoo is a project aiming at a more comprehensive list: launched in July 2007, it has classified over one million galaxy images from The Sloan Digital Sky Survey, The Hubble Space Telescope and the Cosmic Assembly Near-Infrared Deep Extragalactic Legacy Survey. [2]
The Whirlpool galaxy and Abell 2744, a galaxy cluster Superclusters , galactic filaments and voids Notable astronomical objects and their known physical features.
This galaxy filament contains the Perseus–Pisces Supercluster. Pisces–Cetus Supercluster Complex (1987) 1,000,000,000: Contains the Milky Way, and is the first galaxy filament to be discovered. (The first LQG was found earlier in 1982.) A new report in 2014 confirms the Milky Way as a member of the Laniakea Supercluster.
An MeerKAT image of the Galactic Center showing a number of filaments Radio image of a number of parallel filaments in the Galactic Center; Sagittarius A*, the Milky Way's central black hole, is located in the bright region in the bottom right [1] [2] Nonthermal radio filaments from the 4'' resolution MeerKAT mosaic; oriented vertically for space; scales given assuming a distance of 8.2 kpc
In 2007, the parameters for Galaxy were again modified, with final specifications being for a spacecraft 4.0 meters (13.1 ft) in length, 3.3 meters (10.8 ft) in diameter and with 16.7 cubic meters (589.8 cu ft) of interior volume—45% greater than the Genesis modules. It was intended for launch in late 2008.
While it takes light approximately 2.54 million years to traverse the gulf of space between Earth and, for instance, the Andromeda Galaxy, it would take a much shorter amount of time from the point of view of a traveler at close to the speed of light due to the effects of time dilation; the time experienced by the traveler depending both on velocity (anything less than the speed of light) and ...
