WebThe "definitive" version of the Hubble classification was set out in Sandage's article in Galaxies and the Universe. Compared to Hubble's original conception, this version adds the S0 (lenticular) class between ellipticals and spirals. Hubble hypothesized such an intermediate class, but it was only recognized later. WebEdwin Hubble classified galaxies into four major types: spiral, barred spiral, elliptical, and irregular.
