The [CII] Resolved ISM in STar-forming galaxies with ALMA (CRISTAL survey) peered back to when the Universe was only about one billion years old – a mere toddler in cosmic terms. These observations are helping scientists understand how galaxies formed and evolved from primordial gas clouds into the organized structures we see today.

New research led by Dr. James De Buizer at the SETI Institute and Dr. Wanggi Lim at IPAC at Caltech revealed surprising results about the rate at which high-mass stars form in the galactic center of the Milky Way. The researchers based their study primarily on observations from NASA’s now-retired SOFIA airborne observatory, and using data from the U.S. National Science Foundation Very Large Array archive, and focuses on three star-forming regions—Sgr B1, Sgr B2, and Sgr C—located at the heart of the galaxy.
This science was presented at the 246th American Astronomical Society Conference in Anchorage, Alaska on Monday, June 9, 2025, 2:15 PM AK. You can read the full release from SETI.
