Bar lanes channel gas toward the center of the Milky Way, and some of the gas may overshoot the center of the galaxy and collide with the other bar lane rather than accreting onto the galactic center.

A newly discovered brown dwarf in orbit around a subgiant star provides a valuable opportunity to understand how the process of stellar evolution impacts the properties of a sub-stellar companion.

Boulder fields were once thought to be a universal indicator of the presence of wrinkle ridges from tectonic activity, but new research suggests that some wrinkle ridges lack the tell-tale boulder fields.

Nearby galaxy Messier 81 might be home to not just one but two supermassive black holes that are locked in a binary system with an orbital period of 30 years.

Using the first publicly available data from the Daniel K. Inouye Solar Telescope, researchers study how magnetic fields are threaded and connected from the photosphere to the corona.

JWST observations of quiescent (i.e., not actively star-forming) galaxies ~1–2 billion years after the Big Bang show that the size evolution of these galaxies is more complicated than previously thought.
