Bar-shaped elongations of stars are observed in roughly two-thirds of all spiral galaxies. [ 10 ] [ 11 ] Their presence may be either strong or weak. In edge-on spiral (and lenticular) galaxies, the presence of the bar can sometimes be discerned by the out-of-plane X-shaped or (peanut shell)-shaped structures [ 12 ] [ 13 ] which typically have ...

In spiral galaxies, the spiral arms do have the shape of approximate logarithmic spirals, a pattern that can be theoretically shown to result from a disturbance in a uniformly rotating mass of stars. Like the stars, the spiral arms rotate around the center, but they do so with constant angular velocity .
NGC 1300, viewed nearly face-on; Hubble Space Telescope image. A barred spiral galaxy is a spiral galaxy with a central bar-shaped structure composed of stars. [1] Bars are found in about two thirds of all spiral galaxies in the local universe, [2] and generally affect both the motions of stars and interstellar gas within spiral galaxies and can affect spiral arms as well.
2 galaxies Two spiral galaxies currently starting a collision, tidally interacting, and in the process of merger.

Astronomers believe that about 60% of all galaxies are spiral galaxies — and our solar system resides in one of the spiral arms of the Milky Way galaxy. Webb’s observations can help ...
Objects 1–101 are individual peculiar spiral galaxies or spiral galaxies that apparently have small companions. Objects 102–145 are elliptical and elliptical-like galaxies. Individual or groups of galaxies with neither elliptical nor spiral shapes are listed as objects 146–268.
Milky Way - a spiral galaxy that contains our solar system and is visible as a luminous band of light across the night sky. It consists of billions of stars, dust, and gas, and spans roughly ...
