Compact, extremely distant and glowing red, they appear throughout the early universe, but their true nature has remained elusive. One leading idea is that they are supermassive black holes known as active galactic nuclei. However, they don’t behave quite like the active galactic nuclei astronomers observe in the nearby universe. LRDs are common at high redshift, but their numbers fall sharply at lower redshifts. That difference has raised an important question: What happens to these mysterious ob
