Press Releases: US Extremely Large Telescope Program

14 December 2021: Astronomers have made the most precise measurements yet of the motions of stars around the supermassive black hole at the center of the Milky Way. These results, obtained with the help of the Gemini North telescope, show that 99.9% of the mass contained at the very center of the galaxy is due to the black hole, and only 0.1% could include stars, smaller black holes, interstellar dust and gas, or dark matter.

5 November 2021: NSF’s NOIRLab fully supports the scientific vision of Pathways to Discovery in Astronomy and Astrophysics for the 2020s and stands ready, along with our managing organization, AURA, to join our community in advocating for and contributing to the implementation of the survey’s recommendations. NOIRLab along with its partners are honored that the community has ranked the US Extremely Large Telescope Program as the highest ground-based priority in Pathways to Discovery.
