A Hubble Space Telescope image of the supergiant elliptical galaxy ESO 306-17. Supergiant elliptical galaxies are some of the largest galaxies known. The Condor Galaxy is a colossal spiral galaxy disturbed by the smaller IC 4970 .
A 2017 paper suggests that IC 1101 has the largest core size of any galaxy with a core radius of around 4.2 ± 0.1 kpc (13.70 ± 0.33 thousand ly) by fitting a model to a Hubble Space Telescope (HST) image of the galaxy. This makes its core larger than the one observed in A2261-BCG, which is 3.2 kpc (10 thousand ly).
Size (left) and distance (right) of a few well-known galaxies put to scale. The following is a list of notable galaxies.. There are about 51 galaxies in the Local Group (see list of nearest galaxies for a complete list), on the order of 100,000 in the Local Supercluster, and an estimated 100 billion in all of the observable universe.
Voids are immense spaces between galaxy filaments and other large-scale structures. Technically they are not structures. They are vast spaces which contain very few or no galaxies. They are theorized to be caused by quantum fluctuations during the early formation of the universe. A list of the largest voids so far discovered is below.
Zooming In on the Andromeda Galaxy, also known as Gigapixels of Andromeda, is a 2015 composite photograph of the Andromeda Galaxy produced by the Hubble Space Telescope. It is 1.5 billion pixels in size, and is the largest image ever taken by the telescope. [1] At the time of its release to the public, the image was one of the largest ever ...
The cosmic web — ribbons of gas and dust tying galaxies together — are the largest structures in the Universe, and a new study shows they are growing hotter over time.. Utilizing a phenomenon ...
The galaxy is to be found approximately 10° northwest of Alpha Ursae Majoris (Dubhe) along with several other galaxies in the Messier 81 Group. [ 7 ] [ 11 ] Its apparent magnitude due to its distance means it requires a good night sky and only rises very briefly and extremely low at its southernmost limit from Earth's surface, about the 20th ...
[5] [6] As an elliptical galaxy, the galaxy is a spheroid rather than a flattened disc, accounting for the substantially larger mass of M87. Within a radius of 32 kiloparsecs (100,000 light-years), the mass is (2.4 ± 0.6) × 10 12 times the mass of the Sun, [ 47 ] which is double the mass of the Milky Way galaxy. [ 53 ]
