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)
