Stunning visible light images of galaxies show us vast collections of stars, gas, and dust arrayed in great spiral and giant elliptical shapes. But astronomers know that there is much more to a galaxy than meets the eye.

Their true scale reaches well beyond their visible extent and raises the question of whether a galaxy ever really ends. Dr. Corlies will discuss how we measure the faint outskirts of galaxies and whether the findings match our expectations.

Through studies of Nasa's Hubble Space Telescope observations and modern computer simulations we can probe the nature of galaxy formation and advance our understanding of their development.

Speaker: Lauren Corlies, Johns Hopkins University
Host: Dr. Frank Summers

Recorded live on March 7, 2017 at the Space Telescope Science Institute in Baltimore, MD, USA
