  • M31 - The Andromeda Galaxy: Facts, Type, Age, Size, Diameter, Mass . . .
    Andromeda Galaxy Type Galaxies come in various shapes and sizes, with the three primary types being spiral, elliptical, and irregular The Andromeda Galaxy belongs to the spiral galaxy class, characterized by its distinct arms spiraling out from a central core This classification suggests a dynamic structure, with ongoing star formation and a wealth of cosmic activity Andromeda Galaxy Age
  • Galaxy morphological classification - Wikipedia
    Galaxy morphological classification is a system used by astronomers to divide galaxies into groups based on their visual appearance There are several schemes in use by which galaxies can be classified according to their morphologies, the most famous being the Hubble sequence, devised by Edwin Hubble and later expanded by Gérard de Vaucouleurs
  • Galaxy - Elliptical, Spiral, Irregular | Britannica
    Galaxy - Elliptical, Spiral, Irregular: Almost all current systems of galaxy classification are outgrowths of the initial scheme proposed by the American astronomer Edwin Hubble in 1926 In Hubble’s scheme, which is based on the optical appearance of galaxy images on photographic plates, galaxies are divided into three general classes: ellipticals, spirals, and irregulars Hubble subdivided
  • Andromeda galaxy | COSMOS - Swinburne
    Morphology: Sandage and Tammann, in the Revised Shapley Ames catalog, assign M31 a (revised Hubble classification) type of Sb Location: Expectedly, the Andromeda galaxy is in the northern constellation of Andromeda The galaxy is located at 00h 42m 44 3s +41d 16m 09s (J2000 0) and can be observed from latitudes of +90 to about -40 degrees
  • Types of Galaxies | Pictures, Facts, and Information - AstroBackyard
    Explore the main types of galaxies: spiral, elliptical, barred and irregular with stunning astrophotography and insights into how galaxies form, collide evolve
  • galaxy classification
    For example, the Andromeda Galaxy is classified as kS5 de Vaucouleurs-Sandage classification of spiral galaxies SA (ordinary spirals), SB (barred spirals): then in parentheses a lower case s (for S-shaped spirals) or r (for the ringed type)
  • Types of Galaxies - Spiral, Elliptical Irregular Galaxies - Space Facts
    The most widely used classification scheme for galaxies is based on one devised by Edwin P Hubble and further refined by astronomer Gerard de Vaucouleurs It uses the three main types: Spiral Elliptical Irregular then further breaks them down by specific characteristics (openness of spirals, size and extent of bars, size of galactic bulges) In this age of multi-wavelength observing, the sub
  • Messier 31 (The Andromeda Galaxy) - NASA Science
    Apparent Magnitude 3 1 constellation Andromeda object type Spiral Galaxy In January of 2025, NASA's Hubble Space Telescope released this panoramic view of the neighboring Andromeda galaxy It took over 10 years to make this vast and colorful portrait of the galaxy, requiring over 600 Hubble overlapping snapshots that were challenging to stitch
