NGC 1156 is a dwarf irregular galaxy in the Aries constellation of the type ibm. It is considered a Magellanic-type irregular. The galaxy has a larger than average core, and contains zones of contra-rotating gas. The counter-rotation is thought to be the result of tidal interactions with another gas rich galaxy some time in the past. It has a H ...
Map of the Star Wars galaxy (Legends). The Star Wars galaxy contains several broad sub-regions. Their exact definitions fluctuated somewhat during the Legends continuity, but were later formally updated by the new canon continuity when Disney purchased Lucasfilm.
It is a very small dense star, with a radius less than half of the sun's but with a mass nearly 10 solar masses. Very strong stellar winds , with a terminal velocity of 5,000 kilometers per second are causing WR 93b to lose 10 −5 M ☉ /year. [ 3 ]
The characteristics of Seyfert galaxies were first observed in M77 in 1908; however, Seyferts were defined as a class in 1943. [23] First radio galaxy: Cygnus A: Cygnus: 1951 Of several items, then called radio stars, Cygnus A was identified with a distant galaxy, being the first of many radio stars to become a radio galaxy. [24] [25] First ...
Spiral galaxy UGC 12591 is classified as an S0/Sa galaxy. [1] The Hubble sequence is a morphological classification scheme for galaxies invented by Edwin Hubble in 1926. [2] [3] It is often known colloquially as the “Hubble tuning-fork” because of the shape in which it is traditionally represented.
The franchise's books, comics, and video games from Legends describe and depict other Mon Calamari cruisers and successor designs, such as the MC80B Mon Remonda in the Star Wars: X-wing novels, the MC90 star cruiser Galactic Voyager, the Mediator-class battle cruisers, and Viscount-class Star Defenders (which were meant to be the answer to the ...
It has a Trumpler class of I 3 r, indicating it is strongly concentrated (I) with a large range in brightness (3) and is rich in stars (r). [9] M93 is about 3,380 [1] light-years from the solar radius and has a great spatial radius of 10 light-years, [3] a tidal radius of 13.1 ± 2.3 ly, [4] and a core radius of 4.2 ly. [10]
At the centre of the Hubble tuning fork, where the two spiral-galaxy branches and the elliptical branch join, lies an intermediate class of galaxies known as lenticulars and given the symbol S0. These galaxies consist of a bright central bulge , similar in appearance to an elliptical galaxy , surrounded by an extended, disk -like structure.
