Large surveys of galaxies have revealed a bimodal color distribution: most galaxies tend to be red or blue, leaving a gap in the middle known as the green valley. The authors of this paper use morphologies provided by the Galaxy Zoo project to show that not all galaxies take the same quick path through the green valley.

Astronomers have long wished to probe the number of galaxies containing bar structures to ever increasing redshifts. This paper discusses the first results from the Galaxy Zoo Hubble classifications of galaxies out to redshifts of z = 1, in order to study how the fraction of galaxies containing a bar has changed over a cosmic time that has previously not been explored.

Galactic bars have long been associated with many processes affecting galactic evolution. This paper studies how bars affect the star formation rate, mass and structure of a large sample of morphologically classified galaxies.

Galaxy Zoo is a citizen science project that uses volunteers to classify galaxies from the Sloan Digitial Sky Survey as spiral or elliptical. Now the Galaxy Zoo 2 catalogue has gone public, with even more detailed classifications of galaxies, including bars, bulges, spiral arms, and round and squashed ellipticals.

The discovery of a population of red spiral galaxies has caused astronomers to questions the relation between galaxy color and morphology: a closer look at their star formation rates reveals a clearer picture.
