Hannes Gröller
Alumni in Portrait September 2021
His work is about nothing less than saving the world: Hannes Gröller has been working at the University of Arizona for nine years. There, he uses a telescope at night to search for asteroids and comets that come too close to Earth. In this alumni portrait, the leader of our new ARIZONA chapter reveals just how close is too close and what happens in an emergency.
