Monthly Roundup: A Deep View of Planet-Forming Disks with ALMA
Introducing exoALMA: a survey of 15 large, bright protoplanetary disks that has revealed gas structures that point to potential planet formation.

Stars on the Move: New Insights from the Galactic Center
Astrobites reports on a curious cluster of stars moving together near Sgr A*. Is it a stellar coincidence, or a sign of a hidden black hole?
Creation from Collapse: Making Elements in a White Dwarf’s Final Moments
Some neutron stars might arise from the collapse of a white dwarf. Simulations show that this transformation is likely accompanied by a burst of element creation.
A New Theory for Little Red Dots: Shredded Stars Feeding Growing Black Holes
Could tidal disruption events, which happen when a star gets too close to a black hole, explain the unusual properties of little red dot galaxies?
Are Hot Sub-Neptunes Just Failed Hot Jupiters? Maybe.
Astrobites reports on potential formation mechanisms for hot Neptunes, the rarest type of sub-Neptune exoplanets.
Featured Image: The Last Asteroid Pair Discovered by Arecibo
The 1,000-foot-wide Arecibo Telescope discovered nearly 60 binary or triple asteroid systems. 2020 BX12 was the final binary asteroid discovered with Arecibo before the telescope collapsed in 2020.
From Gas to Cluster: Simulating Star Formation in the Early Universe
How do globular clusters, some of the universe’s oldest objects, originate? Recent simulations of early universe star formation provide potential pathways for their formation and how JWST might be able to spot their high-redshift progenitors.
Winds, Jets, and Wigglings from Young Stars and Their Disks
New JWST observations provide a richly detailed look at the jets from young stars still shrouded in dusty disks.
Did That Supermassive Black Hole Rip Apart a Star, or Is It Eating Lunch Like Normal?
Astrobites reports on a radio search for stars that have been ripped apart by supermassive black holes.
Black Hole vs. Magnetized Neutron Star: Matchup Predictions
Monster shocks and a “pulsar-like” black hole phase might form when a black hole collides with a neutron star. Could this cosmic clash produce observable electromagnetic signals?
First Confirmed Planet in a White Dwarf’s “Forbidden Zone”
Brr! A newly confirmed exoplanet orbiting a white dwarf has a temperature of just 186K, making it the coldest exoplanet whose light has been directly detected.
How Squished Is That Planet? Astronomers Measure Oblateness of a Sub-Neptune
HIP 41378f — a cold, puffy exoplanet with four known siblings — becomes one of just a handful of planets with an estimate of its rotation period.
