Highlights from AAS Nova: 30 November – 13 December 2025

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 two weeks; follow the links to read more, or visit AAS Nova for more posts. You can also sign up to receive emails each time a new post is published.
