Support for Astrophysical Observatories and National High-Energy Astrophysics Hubs Act of 2026

S. 4044, the Support for Astrophysical Observatories and National High-Energy Astrophysics Hubs Act of 2026, would establish federal support for astrophysical observatories and create national hubs focused on high-energy astrophysics research. The bill, introduced by Senator Edward Markey (D-MA) in March 2026, is currently under committee consideration.

If enacted, this legislation would aim to strengthen American scientific research infrastructure in astrophysics, potentially supporting telescope facilities and research centers that study high-energy phenomena in space such as black holes, neutron stars, and cosmic radiation. The bill would direct federal resources toward these observatories and research hubs, which could advance scientific discovery and maintain U.S. competitiveness in space science.

As standard legislation, the bill would require presidential signature to become law. It has not yet been voted on by the full Senate and remains in the early stages of the legislative process.
