Between 2014 and 2016 , the European Space Agency ’s Rosetta spacecraft orbit and studied a comet one C of millions of miles from Earth , collecting data on the space stone ’s social organisation and geology . Now , the ESA isasking the publicto study persona of the comet and to report differences in its surface feature over time .
The object is Comet 67P / Churyumov - Gerasimenko and was first observedin 1969 . The comet has an elliptical , 6.5 - year orbit . When Rosettaarrivedat the physical object in 2014 , it became the first ballistic capsule to rendezvous with a comet .
As Comet 67P ( as it ’s known for short ) moved through its scope , the Sun radiate on its different sides . That gave Rosetta a hugely illuminating look at the glacial rock , opinion that were captured in numerous prototype by the onboard OSIRIS tv camera .

“ give the complexity of the imagination , the human eye is much undecomposed at detecting humble changes between images than automated algorithmic program are , ” said Sandor Kruk , an astrophysicist at the Max Planck Institute for Extraterrestrial Physics near Munich , Germany , who dreamt up and start the citizen science project .
Using a tool calledRosetta Zoo , members of the public are encouraged to look at side - by - side images of feature film on Comet 67P that were taken before and after it made its faithful approach to the Sun . Volunteers can manipulate the images by rotating them and soar in , and they can indicate the type of feature of speech they think may be exhibited in the persona ( dust , boulder , or erosive feature article ) , and what ’s changed about it — whether it newly appeared , melt , or only moved .
“ In the retiring few yr , astrophotographers and distance enthusiasts have spontaneously key changes and signs of natural process in Rosetta ’s images , ” enunciate Bruno Merín , the head of the ESA ’s ESAC Science Data Center in Spain , in an agencyrelease . “ Except for a few cases , though , it has not been possible to link any of these events to surface changes , mostly due to the lack of human centre sifting through the whole dataset . We definitely ask more eyes ! ”
The volunteer workplace on the information will be used to bring out maps of alive areas on the comet ’s surface , which scientists will be able to use to make new models of cometic activity . The more eyes there are on these pictorial matter , the more insights can be gleaned about the ancient debris float through our solar system of rules .
