Every day, Astrobites posts a plain-language summary of a recent paper from a different subfield of astronomy, meant to be read in five minutes or less. A rotating team of graduate students from around the world writes the daily digest with the goal of making technical papers accessible to undergraduate students in the physical sciences. While spotlighting a piece of current research and explaining the techniques used, Astrobites also aims to give context to how the work fits into the bigger picture of research in that subfield, giving readers an accessible entry point into a new area of astronomy. In addition to the Daily Paper Summaries, the Classics series summarizes foundational papers in astronomy and the Undergrad Research series amplifies the work of undergraduate students (readers are welcome to submit their own work). Astrobites also posts academic and career advice and personal experiences. Some recent posts include "So You Want to be a Professor of Astronomy?" (July 16, 2021), "#BlackInAstro Experiences" (June 23-27, 2021), and "Quitting A PhD" (June 18, 2021). Readers can scroll the homepage to browse posts organized by category or use the drop-down menus at the top of the page (mobile users will see an expandable menu). Paper summaries are under "Latest Research" and other types of posts are under "Beyond astro-ph." Readers can also check out the "Guides" drop-down menu for standalone posts on subjects from graduate school to astrophysics software. At the bottom of the page, there are listings for Astrobites Sister Sites with content such as K-12 science education, environmental science, cancer research, and soft matter physics, as well as other digests in multiple languages. The project is supported by the American Astronomical Society.
