To find the science observations and data products behind an image, use the Space Telescope Science Institute’s Mikulski Archive for Space Telescopes (MAST). The key distinction: gallery images are processed presentations of infrared measurements; MAST holds Webb’s unprocessed science data and related products.
Where do I find official images?
NASA’s Webb Image Galleries is the most direct starting point for a published image. Search by a target or topic, then use the available categories to narrow the results. NASA says keyword search uses image metadata, and each image’s detail page includes a description and the available download formats and resolutions.
If you do not find an image there, try ESA/Webb’s image gallery and its advanced image search. NASA notes that some Webb images released by ESA/CSA teams, other NASA centers, researchers, or universities may not appear in NASA’s gallery. An image’s absence from one gallery does not by itself show that it is inauthentic.
When sharing an image, retain its official description and credits. The caption provides context about what is shown and how the image was made.

Where does NASA upload them to?
It depends on what you mean by “them.” NASA’s galleries are for finding and downloading published images. The underlying observations and science products are archived at MAST, operated by the Space Telescope Science Institute (STScI). NASA describes MAST as the only location for all of Webb’s unprocessed data.
| Resource | Purpose | What you get | Best for |
|---|---|---|---|
| NASA Webb Image Galleries | Curated, captioned image discovery | Image descriptions and available downloads in multiple formats and resolutions | Viewing or sharing a finished public image |
| ESA/Webb gallery | Another official image-discovery route | Gallery images, descriptions, and credits | Finding or checking images released through ESA/Webb |
| MAST Portal or JWST Mission Search | Searching Webb science observations and products | Observation records, metadata, visualization options, and downloadable data bundles | Investigating or working with the underlying observations |
Where can I download the raw JWST data?
Use MAST. STScI documents two browser-based ways to search Webb science data: the MAST Portal and JWST Mission Search. Search by the target or other identifying observation information, review the matching observation records and metadata, and select observations to retrieve as a bundle. Because the interfaces can change, follow the current guidance in STScI’s JWST Archive Manual rather than relying on a fixed sequence of buttons.
Downloading data is not the same as downloading a finished gallery image. Raw observations are intended for scientific analysis and need appropriate image-processing software and knowledge to turn them into a viewable result. NASA notes that anyone can download and process raw Webb data, but a reader who only wants a high-resolution public image generally does not need to do this.
Why are Webb image colors different sometimes?
Webb observes infrared light, which human eyes cannot see. A released image is processed: measurements from one or more filters are mapped to visible colors so viewers can interpret features and wavelength information. It is not a conventional color photograph of a scene as a human would see it.
Different images can use different filters and color assignments, so colors do not have one universal meaning across all Webb releases. Read the image caption alongside its instrument and filter notes before interpreting a particular color. NASA’s About Webb Images explainer uses a NIRCam example to show how results from multiple filters contribute to an image.

Look for the image on an official NASA, ESA/Webb, or STScI page, and check the description and image credits. NASA warns that fake and AI-generated images are sometimes attributed to Webb. If an image is missing from NASA’s gallery, check ESA/Webb and the credited institution or research team before drawing conclusions; official releases can appear outside NASA’s own gallery.
