It consists of two collections of galaxies in a “dumbbell” shape: the Milky Way and its satellites form one lobe, and the Andromeda Galaxy and its satellites constitute the other.https://en.wikipedia.org › wiki › Local_GroupLocal Group – Wikipedia consists of three large galaxies the Andromeda Galaxy (biggest), our Milky Way (2nd-biggest) and the Triangulum Galaxy (3rd biggest) along with 50 or so much-smaller dwarf galaxies.8 Dec 2021

Where is the biggest galaxy in the world?
IC 1101 is a supergiant elliptical galaxy at the center of the Abell 2029 galaxy cluster and is one of the largest known galaxies. Its halo extends about 600 kiloparsecs (2 million light-years) from its core, and it has a total of about 100 trillion stars.IC 1101 is a supergiant elliptical galaxyelliptical galaxyElliptical galaxies vary greatly in both size and mass with diameters ranging from 3,000 light years to more than 700,000 light years, and masses from 105 to nearly 1013 solar masses. This range is much broader for this galaxy type than for any other.https://en.wikipedia.org › wiki › Elliptical_galaxyElliptical galaxy – Wikipedia at the center of the Abell 2029 galaxy cluster and is one of the largest known galaxies.

What are the 4 types of galaxies and their definitions?
There are four main categories of galaxies: elliptical, spiral, barred spiral, and irregular. These types of galaxies are further divided into subcategories while at the same time other types of galaxies exist based on their size and other unique features. Around 77% of the galaxies observed by man are spiral galaxies.8 Jan 2020

How many galaxies are there in the universe NASA?
The Hubble Space Telescope looked at a small patch of space for 12 days and found 10,000 galaxies, of all sizes, shapes, and colors. Some scientists think there could be as many as one hundred billion galaxies in the universe. This is the picture taken by the Hubble Space Telescope showing thousands of galaxies.
How many galaxy galaxies are there?
Currently, in 2020, it was estimated that there are around 2 trillion galaxies in the observable Universe. Each galaxy is unique, ranging in size from 10,000 light-years to hundreds of light-years.Currently, in 2020, it was estimated that there are around 2 trillion galaxies in the observable Universeobservable UniverseThe comoving distance from Earth to the edge of the observable universe is about 14.26 gigaparsecs (46.5 billion light-years or 4.40×1026 m) in any direction. The observable universe is thus a sphere with a diameter of about 28.5 gigaparsecs (93 billion light-years or 8.8×1026 m).https://en.wikipedia.org › wiki › Observable_universeObservable universe – Wikipedia.

See 13.7 billion years of cosmic evolution in under a minute. Galaxies are collections of stars, gas, dust and dark matter held together by gravity. Their appearance and composition are shaped over billions of years by interactions with groups of stars and other galaxies.13 May 2014
