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 offiste 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 (offsite), and details of the project are available in Linott et al. 2008 (offsite).

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 (offiste). 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).
