This month on All Space Considered, Griffith Observatory welcomed Dr. Joel Leja, Associate Professor of astronomy & astrophysics at The Pennsylvania State University, to discuss his research on the processes of galaxy formation derived from a combination of statistics, machine learning, and deep galaxy surveys with telescopes like the James Webb Space Telescope: #LittleRedDots

The nature of `little blue dots': #LittleRedDots
