Whimsy or wonder? We'll let you decide @NASAWebb recently took a look at the Sagittarius B2 molecular cloud: the most massive, and active star-forming region in our galaxy, located only a few hundred light years from the Milky Way's central supermassive black hole. Astronomers want to figure out why this cloud is so much more active than the rest of the galactic center. While Sgr B2 has only 10% of the galactic center's gas, it produces 50% of its stars. Even with Webb's sensitive infrared capability, which allows it to see through clouds of dust and gas, there are regions so dense that our orbiting telescope can't see through them. These thick clouds are the raw material of future stars—and a cocoon for those still too young to shine. The first three slides in this carousel show Sgr B2 as seen by Webb's Mid-Infrared Instrument, which captured glowing cosmic dust heated by very young massive stars in unprecedented detail. Note that while the dust and gas glow dramatically, all the bright stars disappear from view. In contrast, in near-infrared wavelengths (seen in the last three images), it's the colorful stars that steal the show. Astronomers will seek to discover the masses and ages of these stars to better learn about how they're formed in this dense, active region of the galactic center.

The first three slides depict a swirling patch of red and magenta clouds, with bright blue, six-pointed spots shining through. In the second three slides, the same image is seen in shades of orange, but the stars are much more numerous, filling the screen almost completely. #NASA #Space #Universe #JWST #Astrophotography
