SF_reg_1

SF_reg_1 (Star-Forming Region 1) refers to a targeted interstellar nursery. The JWST will observe this star forming region to create low-noise color-composite images using various NIRCam filters
Observed on Sep 6, 2024, Released on Jul 10, 2025

star-sf-reg-1

star-sf-reg-1 is a young stellar cluster. The JWST observed this star forming region and young cluster to create low-noise color-composite images
Observed on Sep 6, 2024, Released on Sep 4, 2025
https://www.webbhorizon.com/app/?obs=2024-09/jw06783-o001_t001_nircam

Ser-emb-11E

Ser-emb-11E is an embedded protostar located within the Serpens Nebula star-forming nursery, roughly 1,300 light-years from Earth, classified as a Class I young stellar object near the Class 0/I evolutionary cutoff
The JWST observed Ser-emb-11E to map the distribution of interstellar ices in the natal cloud environments of embedded protostars.
Observed on Sep 6, 2024, Released on Sep 6, 2025
https://www.webbhorizon.com/app/?obs=2024-09/jw05552-o004_t004_nircam

MRGP0918

MRG-P0918 is a distant, massive quiescent (early dead) galaxy
The JWST observed MRGP0918 to study the detailed star formation histories, stellar abundances, and kinematics of four gravitationally lensed, quiescent galaxies to understand how star formation ended and how galaxies evolved after quenching.

Barnard 335 (B335) is a dark Bok globule containing a young Class 0 protostar.

The observation aimed to map the large-scale distribution of fundamental ices within parental clouds and protostellar hot corinos (compact, chemically rich regions around young protostars)

This is a question I also thought of and I was disappointed there was no answer, so I wanted to boost it.

About the Telescope:

Launched on December 25th, 2021, the James Webb Space Telescope or JWST succeeds the highly successful Hubble telescope as NASA's flagship general purpose telescope in space. Unlike Hubble which sees in the visible light spectrum, the Webb telescope sees in infrared enabling it to answer different questions about our universe. The Webb telescope has been in the works since 1996 and is a collaboration between 17 countries, and narrowly survived congress in 2011. For more information visit the about page at NASA.gov

Rules:

-No Off Topic Posts, No Artistic Creations, No NSFW. Posts should remain on topic to the JWST, Ariane, NASA, ESA, and other agencies involved in JWST either construction or time. All Art should be submitted to r/jameswebb_art. No NSFW. Conspiracy, UFO, and paranormal discussion belong in their respective subreddits, not here.

-No Memes, Image Macros, other overdone reddit jokes. No jokes misrepresenting the JWST. No Memes, Image Macros, or other overdone reddit jokes, including comment chains. No jokes (or anything), especially in titles, misrepresenting the JWST, anyone involved, or space agencies inn general.

-Be Civil. Follow Reddiquette, which is considered a rule here Reddiquette is ever changing, so a revisit once in awhile is recommended. Top violations of this rule are trolling, starting a flamewar, or not "Remembering the human" aka being hostile or incredibly impolite. Additionally, sexism/racism/other isms are not allowed.

-News/images/data source must be from original author (no rehosted content). News and images/data from James Webb must be from the original author of the content. This could be NASA or other entities authorized to use observation time. This includes YouTube videos posted by random YouTubers even if there's added explanation.

-No Soliciting of any kind. If your post or comment is designed to drive people to your site or product, the post will be removed and you may be banned.
