Also, a population of red spirals was found. These have a different evolutionary path from normal spiral galaxies, showing red spiral galaxies can stop making new stars without changing their shape. Using Galaxy Zoo data for their sample, Tojeiro et al. 2013 found (pg.5): 13,959 red ellipticals, 381 blue ellipticals, 5,139 blue late-type spirals, 294 red late-type spirals, 1,144 blue early-type spirals, and 1,265 red early-type spirals. Chris Lintott stated: "These red spiral galaxies had been lurking in the data and no-one had spotted them. They were staring us in the face. Now we know that a third of spirals around the edges of some clusters of galaxies are red." He also stated: "These results are possible thanks to a major scientific contribution from our many volunteer armchair astronomers. No group of professionals could have classified this many galaxies alone." A team using the Hubble Space telescope has independently verified the existence of red spirals. Meghan Gray stated: "Our two projects have approached the problem from very different directions. It is gratifying to see that we each provide independent pieces of the puzzle pointing to the same conclusion."
