Welcome!

This is the website for Prof. Jacob Bean's group in the Department of Astronomy & Astrophysics at the University of Chicago. The main theme of the group's research is the observational study of planets outside the Solar System ("exoplanets"). We use ground- and space-based telescopes to detect and characterize these worlds. We are also engaged in building new instruments as part of our push towards eventually identifying other Earth-like planets.


See here for a recent talk summarizing some of the group's research.
