With their extremely low surface brightness, ultra-diffuse galaxies are very difficult to detect, but a recent study has spotted one by searching for its globular clusters.
The massive nearby elliptical galaxy Messier 87 hosts one of the most-studied supermassive black holes in the universe. What have researchers recently learned about this black hole’s spin, jets, and flares?
Astrobites reports on JWST observations of a mysterious binary quasar system from cosmic noon.
The troubles continue for planets around the smallest and coolest stars: new research suggests that it’s even harder than previously suspected for these planets to hold on to their atmospheres.
Astrobites reports on the famous Bullet Cluster — what JWST observations reveal about its complex merger history and the constraints these observations place on self-interacting dark matter.
Recent observations of a well-studied but confounding galaxy provide new insights into the structure of low-luminosity active galactic nuclei.
Astrobites reports on research that explores the possibility of impacts delivering organics to the ocean worlds in our solar system.
A new fast and flexible ray-tracing algorithm aims to make the complex world of general relativistic magnetohydrodynamics simulations more approachable.
The final day of AAS 246 included discussions about solar cycle research and the current landscape for science policy and advocacy.
The bunny ears of a jellyfish galaxy, the journey of a 14th-century monk, and 35 years of the Hubble Space Telescope: all this and more on Day 3 of AAS 246.
On Day 2 of AAS 246, we heard about active galactic nucleus feedback, learned how planets fare in systems with multiple stars, and saw fantastic new images of the Sun.
Day 1 of AAS 246 in Anchorage, AK, brought us jets, winds, super-heated stellar coronae, and stunning images of supernovae.
