Message from the researcher
We know there should be a huge number of black holes out there orbiting companion stars or just drifting alone through the cosmos. Lensing is one of the best (and only) ways for us to find them, but we need the help of citizen scientists.

Many astronomers believe that the Milky Way is teeming with black holes, but so far we have only found a handful. In this project you will search for tell-tale signals that may reveal the hidden black holes in our galaxy.
