Astronomers have spent over a decade tracking a unique type of compact dwarf galaxy, which continues to surprise everyone. Known as the "Little Red Dots" for their small, red appearance, these local galaxies look much like the distant galaxies recently observed by the JWST. However, there's a big puzzle. Unlike other active galaxies that show bright, changing lights, these nearby versions hardly budge. Their brightness stays nearly unchanged, and their strong hydrogen emission lines don't flicker much either.
