Galaxies and Astronomical Phenomena

The 2019 National Science Olympiad webinar focuses on stellar evolution in normal and starburst galaxies. Supported by NASA's Universe of Learning, the event covers rules, changes, and the use of a dedicated NASA database. Key topics include galaxy classification, the DSO list, supernovae, gravitational waves, and supermassive black holes. The webinar also explores interacting galaxies and their impact on star formation.
