A new research frontier in astronomy and astrophysics will open in the mid-2020s with the advent of ground-based extremely large optical-infrared telescopes (ELTs) with primary mirrors in the 20-m – 40-m range. U.S. scientific leadership in astronomy and astrophysics will be significantly enhanced if the broad U.S. community can take advantage of the power of these new ELTs.
The National Science Foundation’s (NSF) National Optical Astronomy Observatory (NOAO), the Giant Magellan Telescope Organization (GMTO), and the Thirty Meter Telescope International Observatory (TIO) are working collaboratively to develop a U.S. Extremely Large Telescope (US-ELT) Program.
Strengthen scientific leadership by the U.S. community-at-large through access to extremely large telescopes in the Northern and Southern Hemispheres. This two-hemisphere model will provide the U.S. science community with greater and more diverse research opportunities than can be achieved with a single telescope, and hence more opportunities for leadership.
Our immediate task
Advocacy for frontier research programs led by U.S community scientists that can achieve exceptional advancements in humanity’s understanding of the cosmos. As an essential part of that immediate task, we will work with the U.S. research community to develop concepts for Key Science Programs (KSPs) within major research areas including:
