Oct 22, 2024 · Irregular galaxies have unusual shapes, like toothpicks, rings, or even little groupings of stars. They range from dwarf irregular galaxies with 100 million times the Sun’s …

Oct 22, 2024 · Galaxies come in a variety of shapes, mostly spirals and ellipticals, as well as those with less orderly appearances, usually dubbed irregular. Most galaxies are between 10 …

Since the Hubble sequence is entirely based upon visual morphological type (shape), it may miss certain important characteristics of galaxies such as star formation rate in starburst galaxies …

Spirals are large rotating disks of stars and nebulae, surrounded by a shell of dark matter. The central bright region at the core of a galaxy is called the “galactic bulge”. Many spirals have a …

The shape of the galaxy gives astronomers clues as to the age and types of stars found within it. This is an excellent summary of the different types of galaxies in the universe.

Aug 21, 2023 · Galaxies are complex systems held together by gravity. They're made up of gases, stellar dust and millions — sometimes even billions — of stars, which are accompanied …

Mar 8, 2025 · This Hubble image features spiral galaxy NGC 4536 with sweeping spiral arms, bright blue clusters of star formation, and red areas of hydrogen gas.
