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.

Ice Trapped in Craters on Ceres Is Surprisingly Young
The dwarf planet Ceres hosts water ice in cold, shadowed craters. New research suggests that these ice deposits are remarkably young.

23 April 2024
The Case of Shrinking Planets
Astrobites reports on whether photoevaporation or core-powered mass loss is more likely to be responsible for the exoplanet radius gap.

Early Observations May Separate "Ordinary" Supernovae from Intriguing Ones
If caught just a few days later, SN 2022jox would've looked like just another ordinary core-collapse supernova, but early observations set it apart, revealing the gas expelled in the star's final years.
