Funded through the NSF's Major Research Instrumentation Program, the project will deliver advanced optics, new controllers, and a high-sensitivity tracking detector. These improvements will allow astronomers to simultaneously capture light at multiple wavelengths, offering sharper insights into stars, stellar nurseries, and galaxies.

"It's incredibly rewarding to see what's possible when curiosity meets cutting-edge technology," said Array Director Gail Schaefer. "We are committed to delivering a world-class experience for astronomers exploring the cosmos and this upgrade gives our scientists a powerful new way to image stars in different wavelengths at the same time."

Located on Mount Wilson in California, the CHARA Array consists of six telescopes that combine their light through interferometry, creating one of the world's most powerful tools for detailed stellar imaging. Operated by Georgia State, the array functions as a precision cosmic zoom lens, producing images with extraordinary clarity.

The new instrumentation, expected to be operational in 2028, will resolve long-standing limitations. "With this new NSF award, we will soon have the means to use [the CHARA cameras] simultaneously across the color spectrum," said Doug Gies, Regents' Professor of Physics and Astronomy and director of CHARA. "With these new capabilities, CHARA will be able to explore the universe with unprecedented clarity, inspiring new discoveries and a new generation of astronomers."

Georgia State Provost Nicolle Parsons-Pollard praised the achievement, calling it a milestone for the university's astronomy program. "The enhanced ability to observe stars across the full spectrum of visible and near-infrared light marks a remarkable advancement, firmly positioning Georgia State at the forefront of astronomical research," she said.
