Sa galaxies have very tightly wound arms aroundSa, Sb and ScA 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
These arms are thought to be produced by traveling density waves, which compress and expand the galactic materialResembling festive lights on a holiday wreath, this NASA/ESA Hubble Space Telescope image of the nearby spiral galaxy M74 is an iconic reminder of the impending seasonSpiral galaxys are divided into three main types depending on how tightly wound their spiral arms are:
Spiral galaxies are twisted collections of stars and gas that often have beautiful shapes and are made up of hot young starsSpiral galaxies—of which the Milky Way system is a characteristic example—tend to be flattened, roughly circular systems with their constituent stars strongly concentrated along spiral armsThe discovery of other types of galaxies is fairly recent

The diameter of the spiral galaxies can vary from 5 kilo parsecs to 250 kiloBright knots of glowing gas light up the spiral arms, indicating a rich environment of star formationSpiral galaxy definition is - a galaxy exhibiting a central nucleus or barred structure from which extend curved arms of higher luminosity —called also spiral nebula

Barred Spiral Galaxy Wikipedia
Most spiral galaxies contain a supermassive black hole in the center of the central bulgeIn general, spiral galaxies contain roughly 10 9 to 10 11 solar masses and have luminosity between 10 8 and 2×10 10 solar luminositySpiral galaxy definition, a galaxy having a spiral structure

Spiral Galaxy Facts Definition Space
Spiral galaxies tend to be the brightest galaxies in the universeSpiral galaxies get their name from the shape of their disksSpiral galaxies form a class of galaxy originally described by Edwin Hubble in his 1936 work The Realm of the Nebulae and, as such, form part of the Hubble sequence.Most spiral galaxies consist of a flat, rotating disk containing stars, gas and dust, and a central concentration of stars known as the bulge.These are often surrounded by a much fainter halo of stars, many of which reside in

In a spiral galaxy, the stars, gas and dust are gathered in spiral arms that spread outward from the galaxy's centerSpiral galaxies are mostly found in low-density regions, and very rarely at the center of galaxy clusters
