Taught by Professor Felix J. Lockman | 31 min | Categories: Science
In visible light, scientists had described galaxies as "island universes." But since the advent of radio astronomy, we've seen galaxies connected by streams of neutral hydrogen, interacting with and ripping the gasses from each other. Now astronomers have come to understand that these strong environmental interactions are not a secondary feature-they are key to a galaxy's basic structure and appea...
