Classifying very large data sets is obviously beyond the capability of a single person. Therefore the galaxy classification problem calls for new approaches.

The number of red spirals (red, thick, solid line) and blue early-types (blue, dotted line) in our luminosity-limited sample versus local galaxy density (left) as fractions of our whole sample and
(right) as fractions of all spirals and early-types, respectively.

Left: the change in the red fraction of galaxies in our luminosity-limited sample, divided into contributions due to the variation with local density of the morphological-type fractions (green,
dotted line), the fraction of spirals that are red (red, dot–dashed line) and the fraction of early-types that are blue (blue, dashed line).
