Dark Skies ISS image challenge
More than 100,000 pictures are lost in the ISS archive—help us to classify them.
Alejandro Sánchez de Miguel (UCM) has launched at "Citizen Science Hack Day Challenges" a citizen project to catalog night time pictures taken by astronauts aboard the International Space Station (ISS). The classified and geo-referenced images will be used to Light Pollution studies. More information at Night ISS Wiki Page.
