Like its aquatic eponym, the Tadpole has an oval "head" — the main part of the spiral — and a long, trailing "tail.". Among these are such galaxies as NGC 4753, which has irregular dust lanes across its image, and NGC 128, which has a double, almost rectangular bulge around a central nucleus.
The Andromeda Galaxy (IPA: / æ n ˈ d r ɒ m ɪ d ə /), also known as Messier 31, M31, or NGC 224 and originally the Andromeda Nebula (see below), is a barred spiral galaxy approximately 2.5 million light-years (770 kiloparsecs) from Earth and the nearest major galaxy to the Milky Way.

It is a barred spiral galaxy, with a central bar structure running across its core. Almost all current systems of galaxy classification are outgrowths of the initial scheme proposed by the American astronomer Edwin Hubble in 1926.


Another type of peculiar S0 is found in NGC 2685. The Sombrero Galaxy (M104), which is classified as an Sa/Sb galaxy, in an optical image taken by the Hubble Space Telescope. Don't like the names?

NGC 1302 is an example of the normal type of Sa galaxy, while NGC 4866 is representative of one with a small nucleus and arms consisting of thin dust lanes on a smooth disk.

Galaxy Messier 63 (M63), also known as the Sunflower Galaxy, was the 63rd entry in French astronomer Charles Messier's catalog of celestial objects, published in 1781, and was given its flowery name for the tight spiraling of its many arms, which was thought to be reminiscent of the pattern at a sunflower's center. Galaxy - Galaxy - Types of galaxies: Almost all current systems of galaxy classification are outgrowths of the initial scheme proposed by the American astronomer Edwin Hubble in 1926. Alula is the name of one of the first twin stars discovered.

(A pitch angle is defined as the angle between an arm and a circle centred on the nucleus and intersecting the arm.). Astronomers suspected that this unusual region is the last remnant of a smaller galaxy that collided with the Black Eye over a billion years ago, and was gradually absorbed.

Stellar deaths have been detected in the Whirlpool, as well. Similarly, galaxies are also categorized on the basis of their appearance and/or shape. But opting out of some of these cookies may have an effect on your browsing experience. What's in a name? The Cartwheel's unusual shape was caused by a dramatic, head-on cosmic collision millions of years ago, according to a description on the Chandra X-Ray Observatory website. These intermediate forms bear the designation S0. the brightest moon of Uranus. In Hubble’s scheme, which is based on the optical appearance of galaxy images on photographic plates, galaxies are divided into three general classes: ellipticals, spirals, and irregulars. Finally, there are those with a large, smooth nuclear bulge from which the arms emanate, flowing outward tangent to the bulge and forming short arm segments. The name Andromeda, on the other hand, is derived from the fact that it is located in the Andromeda constellation.

Our site includes quite a bit of content, so if you're having an issue finding what you're looking for, go on ahead and use that search feature there! Observers reported three supernovas — a star's explosive demise — occurring in the Whirlpool during the past 17 years: in 1994, 2005 and 2011.

The numbers specify the entry in that catalog and the position of that galaxy in relation to our sky. Both the arms and the disk of a spiral system are blue in colour, whereas its central areas are red like an elliptical galaxy. A description of the classes as defined by Sandage is given here, along with observations concerning needed refinements of some of the details. In The Hubble Atlas of Galaxies (1961), the American astronomer Allan R. Sandage drew on Hubble’s notes and his own research on galaxy morphology to revise the Hubble classification scheme. The number is expected to be greater than estimated, considering that we are yet to get an answer to one of the most intricate questions posed to the mankind, how big is the universe? Copyright © Universavvy & Buzzle.com, Inc. Sb galaxy NGC 891 as seen edge-on in an optical image taken with the WIYN Telescope at the Kitt Peak National Observatory in Arizona, U.S. Among these, the most popular catalogs are the Messier catalog, a compilation of 110 objects compiled by Charles Messier, and the New General Catalog (NGC), a compilation of 7,840 interesting objects observed in the night sky. The Sombrero is a spiral galaxy, and its unusual hat-like shape is suggested by our perspective on its position in space, viewed edge-on from Earth.

The names are all based on human naming conventions for astronomical bodies or regions, so while your own alien species might use different naming conventions, this generator sticks to the 3 most used types.
