a key factor leading creation of project problem of has been referred data deluge, research produces vast sets of information extent research teams not able analyse , process of it. kevin schawinski, astrophysicist @ oxford university , co-founder of galaxy zoo, described problem led galaxy zoo s creation when set task of classifying morphology of more 900,000 galaxies eye had been imaged sloan digital sky survey @ apache point observatory in new mexico, usa. classified 50,000 galaxies myself in week, mind-numbing. chris lintott, co-founder of project, stated: in many parts of science, re not constrained data can get, re constrained can data have. citizen science powerful way of solving problem.


the galaxy zoo concept inspired others such stardust@home, public asked nasa search images obtained mission comet interstellar dust impacts. unlike earlier internet-based citizen science projects such seti@home, used spare computer processing power analyse data (also known distributed or volunteer computing), stardust@home involved active participation of human volunteers complete research task. in august 2014, stardust team reported discovery of first potential interstellar space particles after citizen scientists had looked through more million images.


when galaxy zoo first started, science team hoped 20–30,000 people take part in classifying 900,000 galaxies made sample. had been estimated perfect graduate student working 24 hours day 7 days week take 3–5 years classify galaxies in sample once. however, in first galaxy zoo, more 40 million classifications made in approximately 175 days more 100,000 volunteers, providing average of 38 classifications per galaxy.


chris lintott commented that: 1 advantage see parts of space have never been seen before. these images taken robotic telescope , processed automatically, odds when log on, first galaxy see 1 no human has seen before. confirmed kevin schawinski: of these galaxies have been photographed robotic telescope, , processed computer. first time have been seen human eyes. .
