Galaxy Zoo

SDSS photometric data also includes morphological classifications of galaxies from the Galaxy Zoo project. More than 200,000 online volunteer citizen scientists. Galaxy Zoo 1 data consists of simple morphological type classification (spiral vs. elliptical) for 893,212 galaxies. Galaxy Zoo 1 data are described in Lintott et al. 2011 , and details of the project are available in Linott et al. 2008 .

New in SDSS Data Release 10 are more detailed classifications of internal structure of the brightest 25% of the Main Galaxy Sample from Galaxy Zoo 2 . Full details of the processes used to combine the votes (from a median of ~40 people per galaxy) and construct debiased classification likelihoods are described in Willett et al. (in press at MNRAS).
