Where do I Find Webb Science Images?

Start with the Webb Image galleries on this site and the Webb Science Image News articles here. Then branch out to other sources listed below which are predominantly repeats though some sites offer additional views, resolutions or image products. The images on this site are official NASA released, peer reviewed science.


Latest Images : the most recent images in reverse chronological order.

More Webb Images: Images by year as well as Webb’s very first images and more.

NASA Webb News : Webb science image feature articles appear in our news stream approximately weekly – go there to not only see the images but read the full story on each.

Webb Blog (offsite) : Webb science images/spectra occasionally appear here that are not yet peer reviewed and therefore not covered by NASA News feature articles. Often co-authored by scientists and engineers, blog posts have a less formal insiders point of view.

Webb FLICKR (Offsite) : 2024 | 2023 | 2022 | 1st Images | Engineering
Our WebbTelescope FLICKR channel contains the full set of Webb’s latest NASA published  images and spectra with brief descriptions and access to various downloadable resolutions.

STScI / WebbTelescope.Org Images: (Offsite) : In Depth– All Images/Products/Detailed Info – Space Telescope Science Institute is where raw Webb data is turned into Webb Science images. Access to all versions including the highest resolution print and uncompressed PNG versions of the latest NASA Published Webb images and spectra including multiple views from various Webb instruments and filters, detailed descriptions, meta-data, uncompressed high resolution image downloads, related products and more.

ESA’s Webb Gallery  (Offsite) :   we often highlight ESA’s picture of the month. You can visit ESA’s Webb Gallery as an alternative source of Webb imagery and information. ESA has an extensive Webb gallery with access to various download resolutions, side by side draggable comparisons of various instruments and missions versions of some images and more.

Webb Images
The background is mostly dark. At the center is a dark orange-brown circle, surrounded by several blazing bright, thick, horizontal whiteish rings. This is Saturn and its rings. There are three tiny dots in the image—one to the upper left of the planet, one to the direct left of the planet, and the lower left of the planet. These are three of Saturn’s moons: Dione, Enceladus, and Tethys, respectively. There is a slightly darker tint at the northern and southern poles of the planet. The rings surrounding Saturn are mostly broad, with a few singular narrow gaps between the broader rings. There is an innermost, thicker ring, and next to that is a brighter, wider ring. Traveling farther outward, there is a small dark gap before another thicker ring. In the thicker ring, there is a narrow faint band. There is then an outermost, faintest, thinnest ring.
A slice of the original image. Webb took its first near-infrared look at Saturn on June 25. The planet appears extremely dark at this wavelength, as methane gas in its atmosphere absorbs sunlight, but its rings stay bright! This image was taken as part of a Webb science program designed to test the telescope’s capacity to detect faint moons around the planet and study its bright rings. Take a closer look here to find details within the planet’s ring system, as well as the moons Dione, Enceladus, and Tethys. Saturn’s rings are made up of an array of rocky and icy fragments – the particles range in size from smaller than a grain of sand to a few as large as mountains on Earth.

A slice of the original image ... Horizontal orange cloud known as Herbig-Haro 46/47, with a central yellow-white blob pierced by red diffraction spikes. A surrounding nebula is seen as a delicate, semi-transparent blue haze. The background is filled with stars and galaxies.
A slice of the orginal image… NASA’s James Webb Space Telescope has captured a tightly bound pair of actively forming stars, known as Herbig-Haro 46/47, in high-resolution near-infrared light. Look for them at the center of the red diffraction spikes, appearing as an orange-white splotch. Herbig-Haro 46/47 is an important object to study because it is relatively young – only a few thousand years old. Star systems take millions of years to fully form. Targets like this give researchers insight into how much mass stars gather over time, potentially allowing them to model how our own Sun, which is a low-mass star, formed – along with its planetary system.

Webb’s Diffraction Spikes

Bright stars stand out in Webb images with their eight sharply defined diffraction spikes.  In the linked infographic and transcript, the science behind Webb’s diffraction spikes is explained (credit: STScI).

How are Webb Images Made?

Images don’t come down from Webb in the beautiful full color renderings you see on this website and elsewhere. Someone has to translate the raw black and white image data into the color, especially since Webb collects light that falls outside of human vision. That’s where people like Joe DePasquale and Alyssa Pagan of the Space Telescope Science Institute come in. Learn how they makes choices about color and other aspects of space images.

What is Webb Observing Next?

JWST science observations are nominally scheduled in weekly increments. Planned schedules will be posted as they are made available. Since the schedules do not take into account unforeseen events, including some target of opportunity observations, it is possible that the actual executed observations will differ from those planned.
