Dwarf galaxy Leo P—the clustering of blue stars at lower right—has an oddball history. After an early burst of star formation, its star production shut down. But unlike most dwarf galaxies, star formation reignited and continues today: https://bit.ly/4j6OgIQ #AAS245
A concentration of bright blue stars occupies the bottom right corner of the image. At bottom center within them is a small blue bubble. The stars and bubble are part of a diffuse dwarf galaxy that extends beyond the image border. Background galaxies are scattered across the image, with some particularly prominent spirals located at upper left and upper right. The background of space is black.
