WebAs one of the first steps towards a coherent theory of galaxy evolution, the American astronomer Edwin Hubble, developed a classification scheme of galaxies in 1926. … WebEach of the following images shows a type of galaxy. Identify each based on observed characteristics. -Barred spiral galaxy: slanted spiral -Dwarf elliptical: small yellow dot -Giant elliptical: big yellow dot -Unbarred spiral: centered spiral Match the galaxy classification on Hubble's tuning fork. -Elliptical (all the way on the left)

The Hubble sequence is a morphological classification scheme for galaxies published by Edwin Hubble in 1926. It is often colloquially known as the Hubble tuning-fork diagram because the shape in which it is traditionally represented resembles a tuning fork. It was invented by John Henry Reynolds and Sir James … Meer weergeven Ellipticals On the left (in the sense that the sequence is usually drawn) lie the ellipticals. Elliptical galaxies have relatively smooth, featureless light distributions and appear as ellipses … Meer weergeven Elliptical and lenticular galaxies are commonly referred to together as "early-type" galaxies, while spirals and irregular galaxies are referred to as "late types".
