Zooniverse’s Space Warps project calls on citizen scientists to help discover elusive objects in the universe by looking through images that have never before been seen. Computer algorithms have already scanned the images, but there are likely to be many more space warps that the algorithms have missed. Space Warps’ creators think that it’s only with human help that all of them will be found.

Einstein’s theory of gravity, General Relativity, predicted that massive objects, such as stars, would bend the space around them such that passing light rays follow curved paths. Evidence for this theory was first obtained by Arthur Eddington in 1919, when during a solar eclipse he observed that stars near the edge of the Sun appeared to be slightly out of position.
