AAS Nova provides brief highlights of recently published articles from the AAS journals, i.e., The Astronomical Journal (AJ), The Astrophysical Journal (ApJ), ApJ Letters, ApJ Supplements, The Planetary Science Journal, and Research Notes of the AAS. The website's intent is to gain broader exposure for AAS authors and to provide astronomy researchers and enthusiasts with summaries of recent, interesting research across a wide range of astronomical fields.

The following are the AAS Nova highlights from the past three weeks; follow the links to read more, or visit the AAS Nova web page for more posts.

24 November 2021
Resolving Io’s Volcanoes Through Occultation Localization
Astronomers have probed the volcanoes of Io at higher resolution than ever before, and their discoveries could help solve the mysteries of this dynamic world.

23 November 2021
Peering Through the Lens of the Milky Way Supermassive Black Hole
Astrobites gives us a preview of what future generations of giant telescopes might see when pointed toward the supermassive black hole at the center of the Milky Way.

22 November 2021
A Detailed Look at the Cygnus X Star-Forming Complex
Astronomers are still trying to understand how stars form from molecular clouds hundreds of light-years across. What can we learn from one of the largest star-forming regions in the Milky Way?

19 November 2021
How Often Do Black Holes Get Kicked Out of Star Clusters?
Gravitational-wave “kicks” might eject black holes from star clusters, preventing them from forming even more massive black holes.

17 November 2021
A Young Star’s Disk Dilemma
Astronomers think CI Tauri hosts a massive planet, but observations of its disk don’t give any sign of one. What’s really going on around this star?

16 November 2021
ASHES to ASHES, Dust to… Star Formation?
Astrobites reports on a search for signatures of protostars deep within dust clouds, where massive stars are thought to form.

15 November 2021
Featured Image: Mapping the Boundaries of a Coronal Hole
A team of scientists has tested our ability to measure “holes” in the Sun’s atmosphere, which may be a main source of the magnetic fields that fill interplanetary space.

12 November 2021
What’s Lurking in the Ticks from Cosmic Clocks?
How can ticking stellar clocks be used to search for ripples in the fabric of spacetime, and how close are we to detecting these waves?

10 November 2021
Extragalactic UFOs: Ultrafast Outflows from Black Holes
Still not aliens, sorry! These otherworldly outflows are powerful enough to unbind galactic gas and accelerate particles to relativistic speeds.

9 November 2021
Searching for Megastructures
Astrobites reports on how megastructures like Dyson spheres can influence the evolution of their host stars.

8 November 2021
Radio Eyes on Titan’s Molecules
What can observations of three nearly identical molecules tell us about how they formed?
