Eric Gaidos (Earth Sciences), Peter Sadowski (ICS), and Dan Huber (IfA) have been awarded $50k from NASA to identify rare dimming events in stars observed by the Transiting Exoplanet Survey Telescope (TESS). They are developing a new artificial intelligence algorithm to systematically identify sudden, subtle and irregular dimming of stars caused by dust that is the building-block of — or debris from —  systems of orbiting planets.  These observations will help us understand the compositions of planets around other stars and how they form.
