Some tightly-packed globular clusters show signs of unseen black holes affecting the movements of their stars. Astronomers are using the Hubble Space Telescope to look for evidence of such hidden monsters.
Galaxy clusters serve as gravitational zoom lenses for the Hubble Space Telescope, magnifying the light from more remote background galaxies to shed light on the nature of such lenses and the distribution of dark matter.
The Hubble Space Telescope captures a textbook example of a luminous Seyfert galaxy and its active galactic nucleus along with details of the galaxy’s structure.
James Webb Space Telescope provides a mesmerising look into Pandora’s Cluster, where multiple groups of galaxies are in the process of merging into a single megacuster.
The Hubble Space Telescope finds a globular cluster with a population of helium-rich red giants that raises questions about currently accepted theories regarding how such clusters form.
