This is a list of known galaxies within 3.8 megaparsecs (12.4 million light-years) of the Solar System, in ascending order of heliocentric distance, or the distance to the Sun. This encompasses about 50 major Local Group galaxies, and some that are members of neighboring galaxy groups , the M81 Group and the Centaurus A/M83 Group , and some ...
Size (left) and distance (right) of a few well-known galaxies put to scale. There are an estimated 100 billion galaxies in all of the observable universe. [1] On the order of 100,000 galaxies make up the Local Supercluster, and about 51 galaxies are in the Local Group (see list of nearest galaxies for a complete list).
For comparisons with the light travel distance of the astronomical objects listed below, the age of the universe since the Big Bang is currently estimated as 13.787±0.020 Gyr. [1] Distances to remote objects, other than those in nearby galaxies, are nearly always inferred by measuring the cosmological redshift of their light. By their nature ...
This is a list of NGC objects 1–1000 from the New General Catalogue (NGC). The astronomical catalogue is composed mainly of star clusters , nebulae , and galaxies . Other objects in the catalogue can be found in the other subpages of the list of NGC objects .
The James Webb Space Telescope has captured scintillating images of 19 spiral galaxies — and the millions of stars that call them home — in unprecedented detail never seen before by astronomers.
The list was compiled by Patrick Moore as a complement to the Messier catalogue. [ 1 ] While the Messier catalogue is used by amateur astronomers as a list of deep-sky objects for observation, Moore noted that Messier's list was not compiled for that purpose and excluded many of the sky's brightest deep-sky objects, [ 1 ] such as the Hyades ...
List of star systems within 70–75 light-years; List of star systems within 75–80 light-years; List of star systems within 80–85 light-years; List of star systems within 85–90 light-years; List of star systems within 90–95 light-years; List of star systems within 95–100 light-years; List of luminous blue variable stars; List of O ...
Comprises such a huge amount of mass that the galaxy cluster noticeably curves spacetime around it, making it into a gravitational lens. Smaller galaxies behind the cluster appear distorted into long, warped arcs around the cluster’s edges.
