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.
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.
Supernova Signatures on Life in the Local Bubble
Clues within Earth’s crust have led astronomers to discover how the solar system’s path through the Local Bubble may have impacted the evolution of our planet’s life.
I Can See Clearly Now: A Deep Learning Method to Remove Clouds from Solar Images
Clouds getting in the way of ground-based solar images? A new machine learning method can identify and remove clouds, revealing the hidden solar features underneath.
Monthly Roundup: Preparing for a Potential Impact
Will the asteroid 2024 YR4 crash into Earth in 2032? Maybe, but probably not. Today’s Monthly Roundup looks at three studies that advance our understanding of asteroid redirection — just in case.
An Icy Disk in the Orion Nebula
The heart of the Orion Nebula, near the massive young stars of the Trapezium Cluster, is a dramatic place for a star to grow up. New research examines JWST images of an unusual protoplanetary disk in this exceptional setting.
