This morning, NASA is releasing even more tantalizing images and data gathered by the agency’s powerful James Webb Space Telescope, showing off vibrant nebulas and exotic galaxies in unprecedented detail. The stunning debut of this cadre of images reveals the diversity of science the observatory will be capable of during its time in space.
The images join the very first picture from the James Webb Space Telescope, or JWST, that NASA and President Joe Biden released yesterday during a special briefing at the White House. That first picture — a portion of the night sky called SMACS 0723 — showcased a dizzying array of thousands of distant galaxies, all bundled into just a tiny dot in the sky about the size of a grain of sand when viewed from Earth. NASA hailed the image as the deepest infrared image of the Universe ever taken. The light from some of the galaxies in the picture had traveled roughly 13 billion years to reach JWST.
Peering deep into the cosmos is just one of the many incredible things that JWST is designed to do. With its massive 21-foot-wide gold-coated mirror, the observatory is tasked with gathering light from the distant Universe, objects within our own Solar System, and even the light surrounding far-off worlds. Today’s images each showcase an exciting ability of the observatory — and they’re only a jumping-off point of what’s to come. It’s got approximately 20 years left in its lifespan to serve up more delicious astronomical treats.
Yesterday, NASA announced that it had officially finished calibrating JWST’s various instruments and tested out all of its different operating modes, meaning the observatory and its tools have all been deemed ready to start collecting data. And there’s a hefty to-do list for JWST. Its first year of science is filled to the brim with various observations of the cosmos, all overseen by scientists around the world who competitively bid to have some precious time with the telescope.
So as dazzling as these first JWST images are, they’re just the tip of a cosmic iceberg, one we can’t fully see until the telescope points its mirror at various patches of the sky.
Whet your appetite by learning more about JWST’s first data and full-color images and what they mean for science operations to come.
This post is developing and will be updated with more images as they come in.
Stephan’s Quintet
The inhabitants of this image are alluded to in the name. It’s a gaggle of five galaxies, surrounded by a colorful array of stars, twinkling blue and red, corresponding to their Universal ages. While one of the galaxies is thought to actually be in the foreground closer to Earth, the rest are repeatedly coming into close contact with another, a cataclysmic dance that distorts their shapes and causes a flurry of star birth within their spiral arms.

JWST was able to capture the spectrum — or the breakdown of light — filtered through the atmosphere of a planet outside of our Solar System, or an exoplanet. It’s a capability that no one truly imagined when the first iterations of JWST were dreamed up in the late 1980s, but it’s shaping up to be one of the more exciting things that the observatory can do.
In 1992, astronomers confirmed the existence of the first known exoplanets, and since then, an entire new field dedicated to hunting for these distant worlds has emerged and flourished over the last few decades. Specifically, scientists are on the hunt for Earth 2.0, a rocky world like ours that may have the right conditions to host life as we know it on its surface. One way to find that out? Look at the air surrounding the exoplanet to see what kinds of gases are present. If the chemical makeup of the atmosphere matches our own, perhaps life exists there too.
Now, JWST may prove to be a valuable tool in that search. Up until now, breaking down the light in the atmospheres of planets has been incredibly difficult, as these objects are both small and faint, often drowned out by the light of the stars that they orbit. But with its precision and power, JWST will be able to collect the light filtered through the very thin layer of gases around a distant planet. That’s exactly what the observatory did with this latest image. It shows the spectrum of the atmosphere of WASP-96 b, a giant planet about half the mass of Jupiter that is mostly comprised of gas itself, according to NASA.
While this exoplanet probably doesn’t host the kind of life we’re looking for, it does have some interesting components in its atmosphere. “What you’re seeing here is the telltale signature, the chemical fingerprint of water vapor… in the atmosphere of this specific exoplanet,” Knicole Colon, an astrophysicist at NASA’s Goddard Space Flight Center, said during a briefing today on the spectrum. That water isn’t liquid, but most likely water vapor. But it shows just how much detail JWST can get of an exoplanet’s atmosphere.
And perhaps there are other worlds that JWST can peer into to tell us more.
Southern Ring Nebula
Another spellbinding nebula, the Southern Ring Nebula, looks like a giant turquoise ring in the night sky, one that actually spans half a light-year wide. It’s also known as the “Eight Burst” Nebula, as it can look like a sideways figure eight from certain viewpoints. The gas of the nebula is actually expanding, moving at nine miles per second, rapidly away from the dying binary star at the structure’s center — the brilliant speck of light in the heart of the image.
SMACS 0723
We all got a taste of this glorious, galaxy-filled image yesterday, but NASA has provided a few more details about what exactly we’re looking at. In the foreground of the image is a massive galaxy cluster located 4.6 billion light-years away. They’re so massive that they warp space and time around them, creating a lensing effect that magnifies the galaxies in the background.
NASA, ESA, CSA, STScI, Webb ERO
“The gravity of the cluster is distorting and warping our view of what’s behind,” Jane Rigby, operations project scientist for JWST at NASA, said during the briefing. “And so there are these galaxies that look stretched and pulled, kind of like they’ve been magnified — because they’ve been magnified by the gravity of the cluster just like Einstein said they would.”
