Citizen Science: Join the Hunt For Space Warps!


Massive galaxies warp space-time around themselves, bending light rays so that we can see around them. It's a phenomenon known as a "space warp". These warps in space provide a very rare and valuable gravitational lens, and now, astronomers are calling on the general population to aid them in the hunt.

Just a couple weeks ago, on May 8, 2013, the SpaceWarps Project was launched as a way to invite everyday citizens to aid in the detection of space warps.

The SpaceWarps project is a gravitational lens discovery engine consisting of thousands of deep sky objects - like galaxies or clusters of galaxies - which may contain warps. With examples of both true and false gravitational lenses, humans are able to sift through the images and spot the unusual appearance of a space warp with relatively little training.
