Sampling the Stars

Stars are forming every moment, gobbling up gas and dust. Precisely how do stars form? How do they grow and change? The Hubble Space Telescope’s Ultraviolet Legacy Library of Young Stars as Essential Standards (ULLYSES) produced an ultraviolet light dataset of young stars to provide incredible insights. Learn what we know about young stars – and the ultraviolet light they emit as they form.
