Beware… space cat! 🐱
Something spooky lurks about 7,500 light-years away.
The watchful eyes of @NASAHubble and @NASAWebb unveiled the Cat’s Head Nebula, just in time for Halloween Eve.
This cosmic cat is in the process of forming new stars! Both telescopes captured this ghostly celestial object, formed by powerful stellar winds and radiation, in different wavelengths of light.
Find out more at the link in our bios… if you dare.

We’re not kitten around! @NASAHubble and @NASAWebb captured a purr-fect view of the Cat’s Head Nebula.
This long thin structure, made of dark, dense dust, looks like the head of a cat, its eye a newborn star still shrouded by the dust and gas from which it formed.
Hubble and Webb’s contrasting and complementary views give us a fuller picture of the features of this object. In the mid-infrared, as seen by Webb, the dust shines brightly while in the near-infrared, Webb can see through the dust to the stars hidden within. In visible light, Hubble's view shows a dark brown pillar of dust, with a yellow ridge along the right side. This bright rim shows gas illuminated and ionized by ultraviolet radiation from nearby massive stars. On the left are some dust pillars seen in the mid-infrared that are not observed in visible light.
It's paw-sible to "fly through" these views with the help of visualizations created by (human) data scientists, which bring Hubble and Webb observations to un-fur-gettable 3-D life. Happy Meow-lloween!

We asked this 8-year-old to draw the famous “Cosmic Cliffs” hidden within the Carina Nebula, based on the famous James Webb Space Telescope image.
The region is actually the edge of a gigantic, gaseous cavity within NGC 3324, roughly 7,600 light-years away. The cavernous area has been carved from the nebula by the intense ultraviolet radiation and stellar winds from extremely massive, hot, young stars located in the center of the bubble, above the area shown in this image. The high-energy radiation from these stars is sculpting the nebula’s wall by slowly eroding it away.
Our artist managed to capture the beauty of this Webb image, along with her version of the telescope itself, a rocket ship, and there is even a cameo of "The Traveler" exploring the cosmos!

The stars are just the night sky's mice...
The first image is Webb's near-infrared view of the Cat's Head Nebula, a star-forming region. Webb can see through the opaque clouds of dust and gas to see the stars forming within. One of these makes up the cat's glowing "eye" and another, with Webb's characteristic eight-pointed diffraction spikes, its whiskers.
The second slide shows Webb's mid-infrared look at the Cat's head, the dust shining brightly. There are structures to the left of the cat visible in the infrared that do not appear in @NASAHubble's visible light view (third slide). The cat's eye is reddish here, glowing from inside the dust. The bright yellow ridge along the cat's "chest" shows gas illuminated and ionized by ultraviolet radiation from nearby massive stars.
Happy Halloween!

*Slams laptop closed for Halloween...and enjoys hauntingly spectacular views of the universe*
Image descriptions:
Each image has the text "*Slams laptop shut for Halloween*" across the center.
1. Webb's Tarantula Nebula, labeled in the bottom left corner. Fluffy tan-colored nebula clouds, with rust-colored highlights, surround a black central area. Within that area, there's one large yellow star with eight long thin points. To the right of this star is a bright star cluster in an oval shape. The stars within the cluster look like tiny pale blue sparkles. Image credit: NASA, ESA, CSA, STScI, Webb ERO Production Team
2. Webb's Rho Ophiuchi cloud complex. Red dual opposing jets coming fill the darker top half of the image, while a glowing pale-yellow, cave-like structure is bottom center, tilted toward two o’clock, with a bright star at its center. The dust of the cave structure becomes wispy toward eight o’clock. Above the arched top of the dust cave three groupings of stars with diffraction spikes are arranged. A dark cloud sits at the top of the arch of the glowing dust cave, with one streamer curling down the right-hand side. The dark shadow of the cloud appears pinched in the center, with light emerging in a triangle shape above and below the pinch, revealing the presence of a star inside the dark cloud. Image credit: NASA, ESA, CSA, STScI
3. Webb/Chandra Region of the Carina Nebula. A composite image of a small portion of the Carina Nebula reveals a striking golden-orange cloud of gas and dust that loosely resembles a ghostly figure. Its glowing hooded head and a sweeping cape-like tail stretch through a star-filled background of rich blues, reds, and greens. Brilliant blue-white stars sparkle in the scene, while bright pink dots of X-ray light reveal young stars scattered across this eerie stellar nursery.

Rest easy, Captain. We have the helm. ✨
Here is Webb’s look at Westerlund 1, a super star cluster - one of the closest clusters of its kind. Super star clusters are young and contain more than 10,000 times the mass of the Sun packed into a small volume. Westerlund 1 is the most massive yet identified in our galaxy, with 50,000 to 100,000 times the mass of the Sun contained within a region less than six light-years across.
Super star clusters are one of the most extreme environments in which stars and planets can form. Because our galaxy is past its peak of star formation, and because such stars live relatively short lives, only a few of these clusters still exist to give us clues to that past era.

Image description: A quote by Captain Jean-Luc Picard, played by Patrick Stewart. "I've come to believe that the stars have always been in my favor." - Jean-Luc Picard. The image shows a dense cluster of bright stars, each with six large and two small diffraction spikes, due to the telescope’s optics. They have a variety of sizes depending on their brightness and distance from us in the cluster, and different colors reflecting different types of star. Patches of billowing red gas can be seen in and around the cluster, lit up by the stars. Small stars in the cluster blend into a background of distant stars and galaxies on black.

Ghosted by the universe, just in time for Halloween!👻
An eerie structure resembling a ghostly figure has been captured by NASA’s Chandra X-ray Observatory and James Webb Space Telescope. Unlike most of the scary associations with this topic, however, this cosmic apparition hosts stellar birth where a new generation of stars is thriving.
The phantom-like structure is part of the Carina Nebula, which is located about 7,500 light years from Earth within the Milky Way galaxy. The Carina Nebula is a vast star-forming region and contains some of the most massive stars in our Galaxy, including the famous Eta Carinae system that astronomers suspect could soon explode as a supernova.

A chicken and egg problem - but make it black holes!
Most galaxies, including our own, have a supermassive black hole at the center. Observations suggest that galaxies and their black holes may grow and evolve together - but did one or the other exist first? Astronomers are using Webb to look back at the early universe to learn more about how the first supermassive black holes formed and their relationships with their host galaxies.

Skeletons don’t make puns. They don’t have the bones for it! But these telescopes do.
Check out some ‘boo’nus images of the skeletons of some of our favorite very undead telescopes, @NASAHubble, @NASAWebb, and Roman!
Image description: A collage of Webb, Hubble, Roman, and Chandra in cleanrooms during their assembly. Text across the middle of the collage is “Telescope Bones.”
@NASAHubble being assembled in the cleanroom at Lockheed Space and Missile Company in Sunnyvale, California. This view was taken after the shroud was placed over the Optical Telescope Assembly.
Image description: The body of the Hubble Space Telescope is placed vertically in a cleanroom with white walls. Two technicians in white protective jumpsuits stand beneath the telescope by a black railing.
@NASAWebb in the @NASAGoddard cleanroom in Nov. 2015 after engineers successfully completed two deployments for Webb’s “wings,” or side portions of the backplane structure that fold up. The backplane, often called the “spine” of the telescope makes up the carbon fiber framework which holds all 18 of the telescope’s mirrors.
Image description: The frame of the Webb telescope’s 18 segment primary mirror sitting up right in the clean room. Each mirror segment location has a round frame to hold it in place. Four technicians in white protective jumpsuits stand near the bottom of the structure, showing how large it is.
NASA’S Roman Space Telescope in the @NASAGoddard cleanroom in Dec. 2024 as the spacecraft went through its integrated payload assembly.
Roman will study dark energy, exoplanets, and more! The spacecraft is on its journey to its final orbit, completing critical milestones along the way. We expect first images by early 2027!
Image description: The Roman Space Telescope structure sits on a silver metal ridged ring in the NASA Goddard clean room. Large pieces of hardware that appear to be stacked on top of each other, together standing about three to four times taller than a person. The Roman Optical Telescope Assembly is on top, and resembles the tip of a dull pencil. Six black beams attach to a small circular object at the top and extend outward and down in a cone-shaped formation t

Need to vent?
Because of a prior gravitational interaction with a neighboring galaxy, M82 undergoes super intense star formation. This image shows its "exhaust system" in action, regulating the galaxy's growth by venting gas outwards.
Multiple NASA missions joined forces to better understand what's going on here. @NASAChandraXray's data (blue), supplemented by NuSTAR data, highlight towering superwinds of million-degree gas blowing thousands of light-years out of the galactic disk, while @NASAHubble's optical light (yellow, orange, and white) shows the galaxy shape, and @NASAWebb and Spitzer observations detail infrared dust emission (red).
Nicknamed the Cigar Galaxy, M82 resides about 12 million light-years away in the constellation Ursa Major.

Double, double toil and trouble; Fire burn and cauldron bubble 🧙♀️
In this Webb image we see a turbulent cauldron of star formation filled with dense clumps of gas. This region is named N159 and is located 161,000 light-years away in the Large Magellanic Cloud, one of the satellite galaxies orbiting our Milky Way.
This region has a lower metallicity (proportion of elements that are heavier than helium and hydrogen) than our Milky Way, giving astronomers an opportunity to learn more about conditions found in the early universe and how stars formed under those conditions.
The colors of this image are interesting because they represent its chemistry. The light orange signifies light emitted by polycyclic aromatic hydrocarbons, an important carbon-based molecule. The pale blue gas clouds are H II gas, ionized by the intense ultraviolet light from massive stars. Dark red filaments across the center of the image are made of cool molecular hydrogen. These filaments are the densest part of the nebula and currently shield new stars from harsh radiation and stellar winds.
Read more at the link in @ESAWebb's bio.
Image Description: A nebula made of clouds of gas and dust with stars forming within. In the center and out to the left it is filled with thin, wispy blue gas that forms delicate layers. Around this are thicker orange clouds with dark ridges. Thin red filaments of gas cross the center of the nebula. Glowing bubbles in the gas contain dense, very bright clusters of stars. In the edges, distant stars are visible as bright points on a dark background.

From simple beginnings to the complex universe we know today 💫
Webb has opened a world of opportunity in studying the early universe and galaxy evolution over time. With its advanced infrared instruments, we’re able to see earlier galaxies than ever before.
This year at the @space_telescopes 2026 symposium, astronomers discussed the chemical simplicity of the early universe and how that impacts the study of galaxy evolution over time.
Webb, in collaboration with NASA’s recently launched Nancy Grace Roman Space Telescope, will continue to bring back data that help astronomers gain a deeper understanding of our universe.
