Researchers investigate the cause of bright, sinuous swirls that are associated with magnetic fields embedded within the Moon’s surface.
Spinning Up: Impacts of Stellar Collisions on Binary Black Hole Mergers
How do interactions binary black holes experience in dense star clusters impact the gravitational waves we detect on Earth? Recent simulations show that stellar collisions leave imprints on the masses and spins of these black holes.
Rapid Microlensing Classification: A Lonely SOBH Story
Astrobites reports on how we can use simulations of stellar populations to rapidly estimate the identity of the lensing object in a microlensing event.
An Update on Asteroid 2024 YR4 from JWST
Though the odds of asteroid 2024 YR4 striking Earth in 2032 have fallen to almost zero, the asteroid still has a slim chance of a collision with the Moon. New JWST observations tell us more about this potential impactor.
Monthly Roundup: News from the High-Energy Universe
An ultra-high-energy neutrino, a galactic PeVatron, and a fading quasar at cosmic dawn are the subjects of today’s Monthly Roundup.
Our Galaxy’s Supermassive Black Hole May Have Had a Companion in the Past
Could there have been two massive black holes in our galaxy’s center at one time? New modeling of fast-moving stars in the Milky Way’s halo suggests the answer is yes.
Crafting Compact Clusters in the Early Universe
Recent simulations tackle the question of how dense star clusters like those spotted by JWST formed in the early universe.
An aMACEing Set of Radio Galaxy Flares
Astrobites reports on two mysterious flares detected from a radio galaxy by the brand new MACE gamma-ray telescope.
Featured Image: Green Seeds at Cosmic Noon
An exploration of galaxies during our universe’s star-formation heyday reveals a population of bright, compact regions called green seeds.
A Late-Stage Infall Renovation: Mapping the Circumstellar Disk of AB Aurigae
What happens when a young star captures some extra gas and dust? New observations of a dusty disk reveals how a late-stage infall event may be influencing planet formation in AB Aurigae.
Gravitationally Lensed Gravitational Waves from Black Holes Around Black Holes
Gravitational-wave detectors have spotted dozens of merging black hole pairs. New research explores whether any of these collisions could have happened in the disk around an accreting supermassive black hole.
