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.
An ultra-high-energy neutrino, a galactic PeVatron, and a fading quasar at cosmic dawn are the subjects of today’s Monthly Roundup.
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.
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.
An exploration of galaxies during our universe’s star-formation heyday reveals a population of bright, compact regions called green seeds.
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.
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.
Astrobites reports on a study that shows that hot stars seem to host fewer small planets than their cooler stellar cousins.
