Featured Image: A Ribbon Around the Heliosphere
When mapping energetic atoms from the edge of our solar system, the Interstellar Boundary Explorer discovered an unexpected ribbon-like feature that researchers are still working to understand.
Them’s the (Balmer) Breaks
Astrobites reports on what might be powering the strange, puzzling young galaxies known as little red dots.
Confirmed at Last: Barnard’s Star Hosts Four Tiny Planets
Following decades of disproven claims, four small exoplanets have been confirmed to orbit Barnard’s Star, the second-closest star system to Earth after Alpha Centauri.
Astronomers Measure Turnover in Initial Mass Function for the First Time
When a gas cloud collapses to form a star cluster, how many objects form, and what are their masses? Research published today provides answers about the low-mass end of the star and brown dwarf formation process.
Observational Obstacles to Detecting Early Universe Supermassive Black Holes
Recent JWST observations have stirred up concerns about over-massive black holes in the early universe. A new study allays these concerns while showing that over-massive black holes are just scratching the surface of the full black hole population.
Baby Galaxies Love to Take 100-Million-Year Naps
Astrobites reports on the star-forming histories of early galaxies and galaxies that form their stars in bursts interspersed with lulls.

Are you considering submitting a paper to an AAS journal? There’s a new tool available now to help you prepare your manuscript.
Between a Nova and a Supernova: The Case of AT 2019abn
What caused this strange red transient that’s too bright to be a nova and too faint to be a typical supernova?
Record-Breaking Pulsating White Dwarf Discovered
A newly investigated ultra-massive white dwarf may provide the best opportunity to study the interior of a white dwarf through its pulsations.
Echoes of a Tidal Disruption Event
New research investigates the infrared echo from a star being ripped apart in a dusty accretion disk around a supermassive black hole.
A Little Red Dot by Any Other Name Would Smell Just like a Green Pea!?
Astrobites reports on whether green pea galaxies are the local counterparts of the famous little red dots that are found in the early universe.
