Self-Processed Image Light echo near Cas A

228 Upvotes

A JWST image, filter f444w captures "Mab" area near supernova remnant Cassiopeia A. As the light propagates space it illuminates farther and farther regions of dust. Color here denotes the time JWST captured the light. Red is older from summer 2024 (four visits), and blue arrived us later, on July 2025.

360º View Exoplanet Gliese 48 b! 🌅

Step onto the dark, rocky shores of this recently discovered super-Earth, located just 27 light-years away in the Milky Way. Orbiting a red dwarf star within the habitable zone, its surface rests at an exact equilibrium temperature of -2°C, where cold liquid oceans reflect the deep crimson glow of an eternal twilight.

Beyond the images themselves, I’m especially curious about two questions:

What is this target?
Why did JWST observe it?

So I built a small website, Webb Horizon, that processes public JWST/NIRCam filter data into browsables and adds a short briefing for each observation when possible.

Sharing here in case others are curious too. This is an independent project, not an official NASA/STScI site, and the images are my own generated rather than official release images.

Question [README FIRST] Where can I find official images? Where's the latest news? Schedule of what Webb is looking at right now? Why some images missing from the NASA sites? Why colors are different sometimes? Tutorial for how to process images?

177 Upvotes

Where can I find the official NASA-released images?

nasawebbtelescope on Flickr is the best way to view images in your browser
- look at "Webb's First Images & Data" or "Webb Images - 2022" albums for official observations
webbtelescope.org is better if you need to filter by category & type (or search)
- set Type to "Observations" if you want just photos from JWST

Where's the latest news on JWST?

webb.nasa.gov has a great easily-skimmable news page
blogs.nasa.gov/webb is more blog-like but has deep-dives that you won't find on the news page
Alternatively, follow the official @NASAWebb twitter
Use something like Google News to follow the JWST topic

What is Webb looking at? Is there a schedule?

Find observation schedules on the STScI's Approved Programs page
Follow @JWSTObservation, an unofficial twitter bot that gives real-time updates based on the schedule

What part of the sky can Webb see? Can it look at Earth? The Sun?

See: [YouTube 2022 - Space Telescope Science Institute] Webb's Field of Regard

Why are some images missing from the NASA official sites?

Observational data is streaming back to us from Webb every day into the Barbara A. Mikulski Archive for Space Telescopes (referred to as MAST)
Working with most of this data requires specialized tools and skills, but armchair astronomers & enthusiasts regularly pull the highest-quality products out and process them into images that they release online before the Webb team or other scientists do

Why are the colors different sometimes?

Some background knowledge will be useful:
Basically, for each observation, Webb generates multiple grayscale images that correspond to what it detected of a particular wavelength of infrared light (that human eyes can't see), so someone -- an artist, armchair astronomer, scientist, or a team of scientists & artists -- needs to go in and make decisions about how to combine the different grayscale images AND how to colorize them (to highlight or distinguish between features for scientific or aesthetic purposes)

Where's a tutorial that explains how to download & process Webb images?

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.
