Black Hole Finder


Utilise the ‘Black Hole Finder’ app to actively participate in the exploration of uncharted celestial events, including the discovery of new black holes. Telescopes worldwide continually capture images of space, occasionally unveiling novel phenomena. Automated programmes sift through this vast stream, presenting a curated selection of images that may showcase intriguing occurrences. However, distinguishing between authentic events, such as neutron star collisions, and optical illusions remains a challenge for computers. This is where the engagement of citizen scientists becomes crucial. The app allows users to review the initial selection of potentially significant images and contribute their judgment on whether an exciting event is unfolding. When multiple users identify an image as noteworthy, it is shared with collaborating astronomers for further investigation.


The app serves as a hub for real-time, global collaboration. Professionals can instantaneously review classifications, pinpointing areas for further investigation. Moreover, they can send alerts for particularly interesting phenomena as they unfold, setting the stage for coordinated, immediate action.
