It is often known colloquially as the “Hubble tuning-fork” because of the shape in which it is traditionally represented. Hubble's scheme divides galaxies into three broad classes based on their visual appearance (originally on photographic plates):

WebPass out Hubble's classification scheme and explain that the tuning fork style diagram represents the evolution of galaxies as they age. Ask them to classify their collection of galaxies using Hubble's scheme. When they are done, discuss the similarities and differences between their scheme and Hubble's scheme. WebIn Hubble's classification scheme, an E0 galaxy is very round and an E7 galaxy is very elongated. The number after the E can be numerically determined by the ratio of the galaxy's major axis (a) to minor axis (b): n = 10 (a - b)/a. Galaxies with higher ellipticities have higher numbers.
