Blue Nugget

Blue Nugget (also called BN) galaxies are a type of distant galaxy that only existed in the early universe. Blue nugget galaxies are small but high mass galaxies undergoing mass bursts of star formation, making many large, bright blue stars. As their stellar population evolves and ages, blue nugget galaxies transition into red nugget galaxies.

"Blue" derives from their blue coloration and "Nugget" derives from their small size.
