The Giant Arc is a large-scale structure discovered in June 2021 that spans 3.3 billion light years. [1] The structure of galaxies exceeds the 1.2 billion light year threshold, challenging the cosmological principle that at large enough scales the universe is considered to be the same in every place (homogeneous) and in every direction ().
Galaxy Quest is a 1999 American satirical science fiction comedy film directed by Dean Parisot and written by David Howard and Robert Gordon. It stars Tim Allen , Sigourney Weaver , Alan Rickman , Tony Shalhoub , Sam Rockwell , and Daryl Mitchell .
Abell 370 is a galaxy cluster located nearly 5 billion light-years away from the Earth (at redshift z = 0.375), in the constellation Cetus. [3] Its core is made up of several hundred galaxies. It was catalogued by George Abell , and is the most distant of the clusters he catalogued.
Justin Long is looking back with gratitude as Galaxy Quest turns 25 — specifically, for the people he worked with, including the late Alan Rickman.. Long made his film debut in the 1999 sci-fi ...
A photograph of a huge plasma arc next to the Andromeda Galaxy, the closest large spiral galaxy to the Milky Way, has won the 2023 Astronomy Photographer of the Year competition for a team of ...
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.
The most powerful telescope to be launched into space has made history by detecting a record number of new stars in a distant galaxy. NASA's James Webb Space Telescope, history's largest and most ...
Listed below are galaxies with diameters greater than 700,000 light-years. This list uses the mean cosmological parameters of the Lambda-CDM model based on results from the 2015 Planck collaboration, where H 0 = 67.74 km/s/Mpc, Ω Λ = 0.6911, and Ω m = 0.3089. [3]
