Thanks for all your help and hard work! We have temporarily paused this project so that we can analyse all the classifications you have provided, and find out whether you have discovered any hidden black holes.

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

About Black Hole Hunters

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.

This project was developed with support from the ESCAPE project. ESCAPE - The European Science Cluster of Astronomy & Particle Physics ESFRI Research Infrastructures has received funding from the European Union’s Horizon 2020 research and innovation programme under the Grant Agreement n° 824064.
