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.
Twenty Thousand Stars Later, They Didn’t Find a Single Planet (and That’s Cool, Too!)
Astrobites reports on a study that shows that hot stars seem to host fewer small planets than their cooler stellar cousins.
Fifteen Years of X-Rays from Andromeda’s Supermassive Black Hole
What has the supermassive black hole at the center of the Milky Way’s galactic neighbor been up to? The Chandra X-ray Observatory provides all the details.
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.
