Shape models help us to interpret the stunning observations from a spacecraft’s recent visit to asteroid Bennu.
Addressing a Gap in Our Knowledge of Black Holes
Models suggest that black holes of a certain mass can’t be produced by supernovae. Gravitational-wave signals from black hole mergers can allow us to test this prediction of “missing” black holes.
Cold Horseshoes in Fast Outflows
Scientists have explored how delicate filaments of cold gas form and survive within the hot, fast-moving surroundings of an active galaxy.
Got ‘Em! An Eccentric, Long-Period Giant Sheds Light on Planet Migration
Astrobites reports on a newly “gotten” failed hot Jupiter that aids in our understanding of giant-planet migration.
Reweighing a Heavy Neutron Star
New observations of a massive neutron star provide clues about these extreme objects’ interiors.
Red, Dead (and Flat?) Galaxies in Distant Clusters
Most galaxies are either star-forming disks or red-and-dead spheroids — but Astrobites reports on new findings that complicate this simple divide.
The Hunt for Wandering Black Holes
How can we spot supermassive black holes lurking outside of their galaxies’ centers? These wanderers may not remain lost!
The Tale of WASP-107b’s Tail
Astrobites reports on the recently discovered tail of exoplanet WASP-107b and the clues it provides about atmospheric escape.

What heats the solar corona to enormous temperatures? The answer may lie hidden here in the quiet Sun.
The Aftermath of Neutron Star Mergers
What does the afterglow of a binary neutron star merger look like? Simulations can give us a fairly good approximation.
Tracking Down Diffuse Gamma Rays
The disk of the Milky Way glows in high-energy gamma-ray photons — but where does this diffuse emission come from?
