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.

Jupiter will be at its biggest and brightest this weekend. Here’s how to see it
An image of the planet Jupiter.

This weekend will bring a striking event for sky watchers, as Jupiter is will be at its biggest and brightest. This is a great opportunity to look up and see one of the brightest objects in the sky.

This is occurring because Jupiter will be in opposition on Saturday, December 7, which means that it is directly opposite from the sun as seen from Earth. This happens every 13 months. In addition, Jupiter is at its closest to Earth just one day earlier, on Friday, December 6. This happens because, although Earth and Jupiter both have orbits around the sun that are almost circular, they are not perfectly circular. Both orbits are slightly oval shaped, called elliptical, and in 2022, Jupiter came its closest to Earth in 70 years. This is still affecting the relative closeness of Jupiter and how big it is in the sky.

James Webb spots ancient Spiderweb cluster that’s 10 billion years old
This image shows the Spiderweb protocluster as seen by Webb’s NIRCam (Near-InfraRed Camera).

A new image from the James Webb Space Telescope shows thousands of glittering galaxies that it spied by peering through clouds of dust and using its infrared instruments to reveal what lies beneath. In the center of the image is the Spiderweb protocluster, which is a group of galaxies in the early stages of forming a "cosmic city."

The light from the Spiderweb has been traveling for an astonishing 10 billion years to reach us, so looking at it is like looking back in time to the early stages of the universe. Astronomers are interested in studying this cluster of over 100 galaxies interacting together because it shows how galaxies clumped together to form groups when the universe was still young.

Webb and Hubble snap the same object for two views of one galaxy
Featured in this NASA/ESA/CSA James Webb Space Telescope Picture of the Month is the spiral galaxy NGC 2090, located in the constellation Columba. This combination of data from Webb’s MIRI and NIRCam instruments shows the galaxy’s two winding spiral arms and the swirling gas and dust of its disc in magnificent and unique detail.

With all the excitement over the last few years for the shiny and new James Webb Space Telescope, it's easy to forget about the grand old master of the space telescopes, Hubble. But although Webb is a successor to Hubble in some ways, with newer technology and the ability to see the universe in even greater detail, it isn't a replacement. A pair of new images shows why: with the same galaxy captured by both Webb and Hubble, you can see the different details picked out by each telescope and why having both of them together is such a great boon for scientists.

The galaxy NGC 2090 was imaged by Webb, shown above, using its MIRI and NIRCam instruments. These instruments operate in the mid-infrared and near-infrared portions of the electromagnetic spectrum respectively, which is why the arms of this galaxy appear to be glowing red. These arms are made of swirling gas and dust, and within them are compounds called polycyclic aromatic hydrocarbons that glow brightly in the infrared. The blue color in the center of the galaxy shows a region of young stars burning hot and bright.
