FAST FACTS
What it is: Sagittarius B2 molecular cloud
Where it is: Approximately 26,000 light-years from Earth,, in the constellation Sagittarius
When it was shared: Sept. 24, 2025
This huge star-forming area is shrouded in a secret: how it has actually handled to produce 50 % of the stars in the area
, regardless of including simply 10 % of the stellar center’s gas.
Astronomers observed this super-efficient outstanding factory utilizing the James Webb Space Telescope (JWST), in the hope of discovering some ideas about its uncommon efficiency. This incredible image is the telescope’s mid-infrared view, recorded by JWST’s Mid-Infrared Instrument (MIRI).
In the imagethe clumps of dust and gas in the molecular complex radiance in tones of pink, purple and red. These clumps are seen surrounded by dark locations. Dark does not imply that these areas are empty or release absolutely nothing; rather, light in these locations is obstructed by thick dust that the instrument can not identify.
JWST’s view of the Sagittarius B2 area in near-infrared light (Image credit: NASA, ESA, CSA, STScI, Adam Ginsburg(University of Florida ), Nazar Budaiev(University of Florida ), Taehwa Yoo(University of Florida); Image Processing: Alyssa Pagan (STScI))In star-forming areas like this one, warm dust and gas and just the brightest stars release in the mid-infrared. This contrasts with the near-infrared image recorded all at once by JWST’s Near-Infrared Camera (NIRCam), which exposes an abundance of stars due to the fact that stars discharge more highly in the near-infrared light.In this MIRI image, the clumps on the right that appear redder than the remainder of the cloud complex represent among the most chemically complicated locations understood, as exposed by previous observations utilizing other telescopes. Astronomers believe this distinct area might hold ideas to why Sgr B2 is more effective at star development than the rest of the stellar.
