... THE SCIENTIFIC OPPORTUNITIES The survey's scientific vision is framed around three broad themes that embrace some of the most exciting new discoveries and progress since the start of the millennium, and that promise to address some of the most fundamental and profound questions in our exploration of the cosmos. The first theme, Worlds and Suns in Context builds on revolutionary advances in our observations of exoplanets and stars and aims to understand their formation, evolution, and interconnected nature, and to characterize other solar systems, including potentially habitable analogs to our own.
From page 2...
... "Pathways to Habitable Worlds" is a step-by-step program to identify and characterize Earth-like extrasolar planets, with the ultimate goal of obtaining imaging and spectroscopy of potentially habitable worlds. "New Windows on the Dynamic Universe" is aimed at combining time-resolved multi-wavelength electromagnetic observations from space and the ground with non-electromagnetic signals to probe the nature of black holes, neutron stars, the explosive events and mergers that give rise to them, and to use signatures imprinted by gravitational waves to understand what happened in the earliest moments in the birth of the universe.
From page 3...
... Finally, neutrino observations are important to understanding some of the most energetic processes in the universe, and the Ice Cube-Generation 2 (IceCube-Gen2) observatory will make advances in important astrophysics questions, although it is beyond the charge of this survey to recommend it.4 Programs that Sustain and Balance the Science Turning to medium-scale missions and projects, the scientific richness of a broader set of themes -- exploring New Messengers and New Physics, understanding Cosmic Ecosystems, and placing Worlds and Suns in Context -- as well as the need to capitalize on major existing investments and those coming online in the next decades drive the essential sustaining projects (Tables S.5 and S.6)
From page 4...
... Enabling Future Visions The community's most ambitious and visionary ideas now require timelines that are pan-decadal and even multi-generational. This is particularly true for NASA's large strategic missions and NSF's premier observatories that are driven by transformative scientific visions but are technically challenging.
From page 5...
... A very large fraction of the astronomical community contributed to this survey through the almost 900 excellent science, activity, program, and state of the profession white papers and through active engagement in town hall meetings. The program laid out in this report represents a collective vision for the future and will require the engagement of a broad community to advance.
