What are the big topics in astronomy research that we’ll be working to address in the next decade? No need to pull out a crystal ball … astronomers have a pretty good guess, and they’ve shared what they think in a series of white papers that are part of the 2020 Decadal Survey.
What’s a Decadal Survey?
The Decadal Survey on Astronomy and Astrophysics (otherwise known as Astro2020) is a process that occurs once every 10 years under the oversight of the National Academies of Sciences, Engineering, and Medicine. During this process, the astronomy community comes together to summarize the current state of the field and identify key priorities for the upcoming decade. These recommendations then serve as a guide for scientists, policy makers, and funding agencies over the next 10 years.
How Does It Work?
Astro2020 begins with various calls for “white papers”, brief write-ups to be submitted by individuals or collaborations within the astronomy community. These white papers are next reviewed by a steering committee made up of prominent members of the astronomy community. Finally, the committee — with input from topical panels, subcommittees, town halls, and more — composes a report that describes the current state of the field, identifies research priorities, and makes recommendations for the next decade.
What’s Happening Now?
The first Astro2020 white-paper call closed in March. The assignment: “succinctly identify new science opportunities and compelling science themes, place those in the broader international scientific context, and describe the key advances in observation, experiment, and/or theory necessary to realize those scientific opportunities within the decade 2020-2030.”
The result? A collection of 573 white papers from the community that beautifully summarizes the most interesting research questions that are driving the field forward at this time. Want a glimpse of what’s interesting in astronomy right now? All you have to do is look through these papers to get a very good idea.
This Decadal Survey, for the first time, the American Astronomical Society is collecting the submitted white papers and making them available in a central location: the Bulletin of the American Astronomical Society. A list of all 573 science white papers has been published there, with titles, authors, and the paper PDFs (for those authors who did not opt out of publication). Each paper is also indexed in the SAO/NASA Astrophysics Data System so that it can be found and cited in the future.
How About a Brief Sample?
Astronomy is an enormous field, and these white papers prove it. Below is a tiny sample of papers covering each of the eight primary thematic science areas (plus two bonus interdisciplinary ones).
What Comes Next?
We’re nowhere near done yet! The papers published now were submitted to the call for science white papers in March. At present, there’s another call open for white papers on activities, projects, and the state of the profession, with a deadline of 10 July. All of these white papers will be included in the BAAS as well. Check back for those later this year, and keep an ear to the ground as the year progresses for more news from Astro2020.

The American Astronomical Society (AAS) have partnered with IOP Publishing to create an exciting new collection of astronomy and astrophysics ebooks to further the AAS mission: "to enhance and share humanity's scientific understanding of the universe."
In keeping with our mission, the entire AAS journals portfolio was made freely accessible as of 1 January 2022. Read more.
