The full view of the study region, showing the NIRCam and MIRI footprints. [Yoo et al. 2026]
This image shows one W51A, of the most active star-forming regions in our galaxy. A research team led by Taehwa Yoo (University of Florida) recently observed this region with JWST, using the telescope’s Near-Infrared Camera (NIRCam) and Mid-Infrared Instrument (MIRI) to record fine structures in the swirling, dusty gas and reveal deeply embedded protostars. The JWST data enabled the team to study two protoclusters that are busily sculpting roughly 10,000 solar masses of gas — each! — into new stars. One protocluster, W51-IRS2 (containing the brightest source in the image above), has excavated a bubble around itself through intense stellar feedback, while the other, W51-E (down and to the right of W51-IRS2, where multiple dust lanes converge), is still being fed by dusty tendrils. For more details on this star-forming region, be sure to check out the full research article linked below.
