A new study led by Dr. James De Buizer of the SETI Institute and Dr. Wanggi Lim of IPAC at Caltech has uncovered unexpected findings about how quickly massive stars take shape near the center of the Milky Way. Using data collected primarily from NASAs now-retired SOFIA airborne observatory, the researchers examined three active stellar nurseries, Sgr B1, Sgr B2, and Sgr C, situated in the heart of our Galaxy.

Despite the Galactic Center containing far denser concentrations of gas and dust than other parts of the Milky Way, the formation of massive stars (those more than 8 times the mass of our Sun) appears to occur at a slower pace there.

To investigate further, the team compared these three regions with others of similar size located farther from the center, including areas closer to our solar neighborhood. Their findings confirmed that the rate of new star formation near the Galactic Center is significantly lower than average. Even though the region holds the kind of dense, turbulent clouds that typically give rise to large stars, these environments seem to struggle to produce them.
