Rubin Observatory will bring new capabilities to the studies of dark matter and dark energy.

Just like we orbit the sun and the moon orbits us, the Milky Way has satellite galaxies with their own satellites. Drawing from data on those galactic neighbors, a new model suggests the Milky Way should have an additional 100 or so very faint satellite galaxies awaiting discovery.

The approach could advance our understanding of fundamental forces under extreme conditions with applications from astrophysics to fusion research.

Nearly 200 guests attended a symposium on fundamental physics to celebrate the former deputy director’s numerous scientific contributions, which continue to have a tremendous impact on our understanding of the subatomic world.
