Pre 2020 Decadal Reports

This page describes the activities of NASA's Astrophysics Division in preparation for the 2020 Decadal Survey. To learn more about Astro2020: Decadal Survey on Astronomy and Astrophysics process, please visit the National Academies website. Prior Decadal Reports are also available on that site.

Listed below are the final reports from the NASA's 2020 Astrophysics Decadal Studies, both the Large and the Probes Mission Concept Studies, and other activities. The reports represent the culmination of four years of intense work by the astrophysics community, with thousands of scientists involved and thousands of page written. This public page serves as NASA's submission to the 2020 Decadal Survey Committee.

The image is divided horizontally by an undulating line between a cloudscape forming a nebula along the bottom portion and a comparatively clear upper portion. Speckled across both portions is a starfield, showing innumerable stars of many sizes. The smallest of these are small, distant, and faint points of light. The largest of these appear larger, closer, brighter, and more fully resolved with 8-point diffraction spikes. The upper portion of the image is blueish, and has wispy translucent cloud-like streaks rising from the nebula below. The orangish cloudy formation in the bottom half varies in density and ranges from translucent to opaque. The stars vary in color, the majority of which have a blue or orange hue. The cloud-like structure of the nebula contains ridges, peaks, and valleys – an appearance very similar to a mountain range. Three long diffraction spikes from the top right edge of the image suggest the presence of a large star just out of view.
