A survey of the largest gravitationally bound structures in the universe seeks to understand why some clusters are better gravitational lenses than others.
Can Solar Dimming Shine a New Light on Coronal Mass Ejections?
The brightness of the Sun’s corona could indicate when nasty space weather events are headed our way.
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.
