Gaia Discovers a Swarm of Black Holes Roaming the Milky Way

Astronomy, Planetary Science /

Palomar 5, a seemingly calm star cluster, may hide a swarm of over 100 stellar-mass black holes. Spanning 30,000 light-years and located 80,000 light-years away, it provides clues about star cluster evolution and tidal stream formation. Unique in its loose structure and 20-degree tidal stream, Palomar 5 contrasts with typical dense globular clusters of ancient
