Bringing Supermassive Black Hole Mergers to Light
With gravitational waves from supermassive black hole mergers still out of reach, astronomers are exploring other ways to track them down.
An Intracluster Investigation via Radio Rotation
Astrobites reports on how magnetic fields in galaxy clusters evolved throughout cosmic history and what these fields can tell us about magnetism in the early universe.
Taking a Closer Look at SPRITEs with Hubble
What can visible-light observations tell us about an unusual class of moderately luminous infrared transients?
Seeking Missing Matter in Hot Halos
Astronomers study photons from the early universe to search for hard-to-find matter in Milky Way-like spiral galaxies.
Finding Strange Stars with Primordial Black Holes
Extremely dense stars composed entirely of elementary particles called strange quarks might exist throughout the universe. Can gravitational waves emitted from an encounter with miniature black holes reveal them?
A Spiral Galaxy That Doesn’t Play by the Rules
Astrobites reports on a spiral-shaped impostor found where an elliptical galaxy is meant to be: shining brightly in the center of a galaxy cluster.

Close binary system R Aquarii dazzles in archival observations, revealing diffuse X-ray emission for the first time.
Tidal Dissipation Makes the Binary Go ‘Round
How do binaries with circular orbits get that way? A new study explores how waves inside stars can nudge an orbit to circularize.
