Webb explores effect of strong magnetic fields on star formation

The MeerKAT radio telescope shows the plane of the Milky Way galaxy, with a graphic pullout highlighting a much smaller region on the right, captured by the James Webb Space Telescope’s near-infrared light observations. The MeerKAT image is colored in blue, cyan, and yellow, with a very bright white-yellow center that indicates the location of the Milky Way’s supermassive black hole. Painterly bubbles of various sizes, clouds, and vertical brushstroke-like streaks make up the radio image. The Webb inset shows stars and gas clouds in red, with an arching cloud of bright cyan that contains many straight, needle-like features that appear more crystalline than cloudy.
An image of the Milky Way captured by the MeerKAT (formerly the Karoo Array Telescope) radio telescope array puts the James Webb Space Telescope’s image of the Sagittarius C region in context. Like a super-long exposure photograph, MeerKAT shows the bubble-like remnants of supernovas that exploded over millennia, capturing the dynamic nature of the Milky Way’s chaotic core. At the center of the MeerKAT image the region surrounding the Milky Way’s supermassive black hole blazes bright. Huge vertical filamentary structures echo those captured on a smaller scale by Webb in Sagittarius C’s blue-green hydrogen cloud.
