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.
Messier 82 (Star)bursts onto the Scene!
Astrobites reports on the results of a cosmic-ray investigation of the starburst galaxy Messier 82 using the VERITAS gamma-ray telescopes.

What at first appeared to be an unremarkable low-mass galaxy cluster has been revealed to host a rare pair of parenthesis-shaped radio sources.
To Be or Not to Be Aligned: Exploring Spin–Orbit Alignment Trends for Exoplanetary Systems
What is pulling exoplanet XO-3b out of alignment with its host star? A recent study explores the system and reveals an emerging trend that provides a boundary for planet formation mechanisms.
