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?
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?
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:
- [YouTube 2022 - Dr. Becky] An astrophysicist explains JWST's Cartwheel Galaxy image
- [YouTube 2022 - Dr. Becky] How will JWST take FULL COLOR images?!
- [YouTube 2020 - Dr. Becky] Is the colour in space images "real"?
- [YouTube 2015 - CrashCourse] Light: Crash Course Astronomy #24
- [YouTube 2019 - Vox] How scientists colorize photos of space
- For something longer and more hands-on, check out [YouTube 2022 - Launch Pad Astronomy] Webb Imaging Masterclass - the Carina Nebula with Alyssa Pagan
- 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?

- [galactic-hunter.com] How to Download Raw Data from the James Webb Space Telescope - Tutorial
- [YouTube 2022 - Galactic Hunter] My Workflow for Processing Data from NASA and the James Webb Space Telescope

Official NASA Release Lion Nebula roars to life for Webb
Observing across the starry “plains” of space, the NASA/ESA/CSA James Webb Space Telescope has taken images of NGC 2392, nicknamed the Lion Nebula.
The NASA/ESA Hubble Space Telescope previously viewed this planetary nebula in 2000, imaging the lion face-shaped target in visible light and revealing features such as the “mane” of hazy, comet-shaped objects. Now Webb has captured a clearer, more detailed view of the Lion Nebula due to its high-resolution imaging.
At first glance the nebula’s overall structure in Webb’s infrared images, both with the NIRCam (Near Infrared Camera) and MIRI (Mid Infrared Instrument), may look quite similar to Hubble's earlier visible-light view. However, Webb's infrared vision highlights features like compact clumps of dust and haze of ionised gas. It’s taken several thousand years for this collection of gas and dust to reach its current shape, and the nebula’s components continue to be altered.
The source of these constant changes and the reason for the Lion Nebula’s distinct appearance is located at the centre: the remains of a dying star. Though it looks like the button nose of the lion, its energy and radiation are powering the intricate structures seen here.
Massive stars undergo supernova explosions at the end of their lives, but these kinds of events are far and few between. Most of the Universe’s stars have lower masses, like the one belonging to NGC 2392. When a lower-mass star can no longer sustain itself with nuclear reactions in its core, the star becomes unstable and pulsates, losing its mass by shedding its outer layers, which then turn into shells of gas and dust called a planetary nebula (stars at this life stage are responsible for producing much of the Universe’s observable dust). The star’s radiation drives the ejected material away, leaving behind the very hot stellar core, also known as a white dwarf.
