The James Webb Space Telescope has turned its powerful gaze on a chunk of the Cat’s Paw Nebula (NGC 6334), revealing a 'toe bean' of newborn stars sculpting their own cloaks of cosmic gas and dust with their fiery energy.
This image has been released to mark the Webb Telescope's third birthday, revisiting a well-known object in a new light.
More Webb images
4,000 light-years from Earth, the Cat’s Paw Nebula is one of the Milky Way’s most active star-forming regions.
Webb’s Near-Infrared Camera (NIRCam) enables astronomers to peer through the gas and dust to reveal secrets that would normally be invisible to the human eye.
Chaos in the Cat’s Paw
Inside the Cat’s Paw Nebula, scorching hot young stars are lighting up the surrounding dust and gas with brilliant starlight, much of it visible in Webb’s infrared image as a vibrant blue glow.
These stars emit powerful radiation and stellar winds that blast away the gas and dust – essential star-forming ingredients – stifling future star formation.
The Opera House in close-up detail
Zoom in on the 'toe bean' at the top centre of the image and you’ll see a striking structure: a tiered, circular feature nicknamed the 'Opera House'.
Glowing blue clouds swirl above bright yellow stars and dense ribbons of dark dust.
One standout star, marked by Webb's distinctive diffraction spikes, is carving out a shell-like pocket in the nebula, but hasn’t yet pushed all the surrounding gas away.
Nearby, odd formations, including a patch shaped like a tuning fork, hint at areas where dust is so thick it blocks the light behind it.
These dark spots aren’t empty, but are instead hiding stars still in the earliest stages of formation.
Seeing star formation
The central region of the image reveals glowing red clumps nestled in brown dust: telltale signs of star formation in action.
These regions are still shrouded in dense material, making them difficult to spot without infrared instruments like Webb’s.
The toe bean in the lower left shows off a few bright, sharply defined stars, their clarity hinting that they’ve already blown away much of the surrounding dust.
But just below them, dusty filaments remain, likely shielding baby stars still in the making.
A particularly bright yellow patch on the right is another giveaway: a massive star trying to shine through its dusty cocoon.
A nebula in motion
In the top right of the image is an eyecatching red-orange oval. Scientists believe this is a pocket of dust just beginning its star-forming journey.
There are hints of activity here: subtle signs of veiled stars and a dynamic bow shock (a wave of gas and dust pushed by a high-speed stellar wind), pointing to a bright, energetic source buried within.
Even in this one small region of the Cat’s Paw Nebula, the James Webb Space Telescope reveals a dynamic, evolving environment, where stars are being born and shaping their surroundings.
