See distant galaxies sparkling in James Webb’s biggest image yet

The wonders of the universe are on full display once again thanks to the James Webb Space Telescope. A team from a Webb survey program has released the largest Webb image yet, showing a dazzling array of galaxies spread across the background of space.

The image is from the CEERS or Cosmic Evolution Early Release Science program, which surveys a patch of the sky near the handle of the Big Dipper constellation. The aim of the survey is to search for extremely distant galaxies by looking at a generally dim area of the sky that is far away from bright light sources, such as the plane of the solar system and the center of the Milky Way. By looking at this dim area, Webb can see very faint distant galaxies as they aren’t blotted out by nearer bright light sources.

This image, from a patch of sky near the handle of the Big Dipper, is part of a larger mosaic taken with the Near Infrared Camera (NIRCam) on the James Webb Space Telescope. This is one of the first images obtained by the Cosmic Evolution Early Release Science Survey (CEERS) collaboration.

“I have been waiting so long to share this, and it is finally time!” researcher Rebecca Larson cheerfully announced on Twitter. “Do you want to see THE BIGGEST IMAGE #JWST has taken of galaxies so far?! Our color mosaic image from @ceers_jwst is ready, and there are SO MANY GALAXIES in it!”

“Check out our amazing color image,” lead researcher Steve Finkelstein chimed in as well. “Download the high-res version and lose yourself in all the galaxies!”

As the researchers suggest, you should go to the CEERS website to see the high-resolution image in all its incredible detail. This is Webb’s largest survey area yet and consists of four images of the 10 total planned for the survey, taken using Webb’s NIRCam instrument in June 2022. More observations are scheduled for later this year.

This image—a mosaic of 690 individual frames taken with the Near Infrared Camera (NIRCam) on the James Webb Space Telescope—covers an area of sky about eight times as large as Webb’s First Deep Field Image released on July 12. It’s from a patch of sky near the handle of the Big Dipper. This is one of the first images obtained by the Cosmic Evolution Early Release Science Survey (CEERS) collaboration.

As well as bringing us stunning images to look at, such surveys play an important role in identifying interesting targets for follow-up study. Included in this mosaic are objects like a set of interacting galaxies dubbed the “Space Kraken,” a supernova spotted in a pair of interacting galaxies, and an extremely distant galaxy named after Finkelstein’s daughter Maisie.

Further surveys are to come with Webb once CEERS wraps up, including the Next Generation Deep Extragalactic Exploratory Survey, or NGDEEP, and the James Webb Space Telescope Advanced Deep Extragalactic Survey, or JADES.

Researchers discover a 320-mph jet stream around Jupiter’s equator
This image of Jupiter from NASA’s James Webb Space Telescope’s NIRCam (Near-Infrared Camera) shows stunning details of the majestic planet in infrared light. In this image, brightness indicates high altitude. The numerous bright white "spots" and "streaks" are likely very high-altitude cloud tops of condensed convective storms. Auroras, appearing in red in this image, extend to higher altitudes above both the northern and southern poles of the planet. By contrast, dark ribbons north of the equatorial region have little cloud cover. In Webb’s images of Jupiter from July 2022, researchers recently discovered a narrow jet stream traveling 320 miles per hour (515 kilometers per hour) sitting over Jupiter’s equator above the main cloud decks.

The James Webb Space Telescope might be best known for its study of extremely distant galaxies, but it is also used for research on targets closer to home, like planets within our solar system. Last year, the telescope captured a stunning image of Jupiter as seen in the infrared wavelength, and now scientists who have been working on this data have published some of their findings about the planet -- including a brand-new feature that they identified in its atmosphere.

James Webb captures a gorgeous stellar nursery in nearby dwarf galaxy
This new infrared image of NGC 346 from NASA’s James Webb Space Telescope’s Mid-Infrared Instrument (MIRI) traces emission from cool gas and dust. In this image blue represents silicates and sooty chemical molecules known as polycyclic aromatic hydrocarbons, or PAHs. More diffuse red emission shines from warm dust heated by the brightest and most massive stars in the heart of the region. Bright patches and filaments mark areas with abundant numbers of protostars. This image includes 7.7-micron light shown in blue, 10 microns in cyan, 11.3 microns in green, 15 microns in yellow, and 21 microns in red (770W, 1000W, 1130W, 1500W, and 2100W filters, respectively).

A gorgeous new image from the James Webb Space Telescope shows a stunning sight from one of our galactic neighbors. The image shows a region of star formation called NGC 346, where new stars are being born. It's located in the Small Magellanic Cloud, a dwarf galaxy that is a satellite galaxy to the Milky Way.

The star-forming region of the Small Magellanic Cloud (SMC) was previously imaged by the Hubble Space Telescope in 2005, but this new image gives a different view as it is taken in the infrared wavelength by Webb instead of the optical light wavelength used by Hubble.

Zoom into an incredibly detailed James Webb image of the Orion nebula
A short-wavelength NIRCam mosaic of the inner Orion Nebula and Trapezium Cluster.

A new image from the James Webb Space Telescope shows the majesty of the gorgeous Orion nebula in tremendous detail. The European Space Agency (ESA) has shared an extremely high-resolution version of the image that you can zoom into to see the details of this stunning cloud of dust and gas which hosts sites of star formation where new stars are being born.

The full image is available to view in the ESASky application, where you can zoom in a compare images of the same target taken in different wavelengths. There's also a very large version of the image if you want to download and pursue it at your leisure.
