Welcome to /r/JamesWebb, the subreddit for NASA's James Webb Space 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.

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.

JWST and Hubble Side-by-side Image of Spiral Galaxy NGC 2090
This self-made image composition allows for a straightforward comparison between the images of Webb and Hubble, as both captured the same galaxy during the same week.
NGC 2090 was one of many galaxies studied by the NASA/ESA Hubble Space Telescope to refine the measurement of the Universe’s expansion rate, or ‘Hubble constant’. This can be done by observing a special type of variable stars named ‘Cepheids’ in relatively nearby galaxies. The Cepheid-based measurement, conducted in 1998, determined NGC 2090 to be 37 million light-years away from Earth. In contrast, according to the newest measurements, NGC 2090 should be slightly farther away, at 40 million light-years. To this day, Hubble is surveying galaxies in visible and ultraviolet light; alongside this Webb image and new Hubble image of NGC 2090 has also been published this week.

Webb Traces Swirling Spiral Arms in Infrared
The spiral galaxy NGC 2090, located in the constellation Columba. This combination of data from Webb’s MIRI and NIRCam instruments shows the galaxy’s two winding spiral arms and the swirling gas and dust of its disc in magnificent and unique detail.
NGC 2090 had been well studied as a very prominent nearby example of star formation. Described as a ‘flocculent’ spiral, this galaxy has a patchy, dusty disc and arms that are flaky or not visible at all. We can see those patterns well in Hubble's visible-light images. However, Webb’s NIRCam near-infrared data reveal the spiral arms with remarkable clarity.
At the same time, Webb’s MIRI captures the mid-infrared light from the carbon-based compounds along the many strands of gas and dust. This MIRI data is pictured as red in the Webb image.
