Spiral galaxies form a class of galaxy originally described by Edwin Hubble in his 1936 work The Realm of the Nebulae [1] and, as such, form part of the Hubble sequence.
The spiral arms are practically incandescent with orange and red gas in Webb’s imagery. The images will be used to help astronomers determine the distribution of gas and dust in spiral galaxies ...
A spiral galaxy is a type of galaxy characterized by a central bulge of old Population II stars surrounded by a rotating disc of younger Population I stars. A spiral galaxy maintains its spiral arms due to density wave theory .
Supergiant elliptical galaxies are some of the largest galaxies known. The Condor Galaxy is a colossal spiral galaxy disturbed by the smaller IC 4970 . It is the largest known spiral galaxy with the isophotal diameter of over 717,000 light-years (220 kiloparsecs ).
The telescope snapped pictures of a relatively close spiral galaxy that is a ringer for our own Milky Way. Although the Hubble Space Telescope previously observed the heart of this galaxy, Euclid ...
2 galaxies Two spiral galaxies currently starting a collision, tidally interacting, and in the process of merger.

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.
However, infrared images of the inner part of the galaxy reveal a prominent bar not seen in visual light, [11] and for this reason it is now considered a barred spiral. [12] Messier 77 is the largest member of a small group of galaxies, [ 13 ] which includes NGC 1055 , an edge-on spiral galaxy likely twisted by gravitational interactions with ...
