JWST-GC program update: we have MIRI coverage of ~half of the field that NIRCAM covers. We use MIRI in 'coordinated parallel' mode, which means we get MIRI data _almost_ for free when we take NIRCAM images. We can make 3-color images for those few regions

Observations for the JWST Galactic Center Legacy Program (id 10678) are scheduled to start within a week. These will immediately become public, but they are going to be a massive mosaic - 140 observations. We'll be processing those data; stay tuned at starformation.astro.ufl.edu/jwst-gc/moni...

Today was a great day for me on professional and personal levels, so I will share something even greater: a JWST observation of the centre of our galaxy! 🔭 This is Sagittarius B2, a molecular cloud a few hundreds light years away from SgrA*, as seen by MIRI and processed by me!

The JWST Galactic Center legacy program starts observing next week: www.stsci.edu/jwst-program.... We'll be publishing advanced data products (combined images) as soon as they're ready.

Researchers use James Webb Telescope to reveal hidden details of W51 star formation

Stars in the W51 region are very young and massive, and using the telescope gave the team the ability to view the early stages of star formation.

Wonderful MIRI imaging of Sgr B2 by Alyssa Pagan. This inspires my confidence in boldly processing the brilliant colors of JWST's MIRI instrument.

Webb's Mid-Infrared Instrument captured glowing cosmic dust heated by very young massive stars in unprecedented detail in Sgr B2. Note that while the dust and gas glow dramatically, all the bright stars disappear from view.

In contrast, in the near-infrared, it’s the colorful stars that steal the show in Sgr B2. Astronomers will seek to learn more about their masses and ages, to better learn about how stars are formed in this dense, active region of the galactic center.
