Black Holes Lurking in Nearby Star Cluster Pose Closest Threat to Earth

The Hyades star cluster in the constellation Taurus, located 150 light-years away, may be hiding a stellar-mass black hole. Astronomers compared observations of the cluster with N-body simulations and found that the best model predicts the presence of 2 or 3 black holes. However, the results are not conclusive, and further observations are needed to confirm the existence of a black hole in the cluster.
