Dust that once hid these secrets is now transparent
Thirty-five million light-years away, the Squid Galaxy has long concealed its innermost nature behind curtains of dust — a reminder that the universe reserves its deepest truths for those who learn to see differently. The James Webb Space Telescope, armed with infrared vision, has now pierced that veil, revealing a bar of stars and gas never before observed, and sharpening our view of a galactic core that may house not one but two supermassive black holes in mutual orbit. A high-energy neutrino traced to this nucleus in 2022 hints that the galaxy may function as one of the cosmos's rarest engines: a natural particle accelerator of almost incomprehensible scale. What was once hidden is becoming, slowly, legible.
- For decades, thick dust clouds have made the Squid Galaxy's core effectively invisible, leaving astronomers to theorize about one of the nearest and brightest active galactic nuclei without ever truly seeing it.
- JWST's infrared cameras have now cut through that obscuration, exposing a bar structure — a ribbon of stars, gas, and dust crossing the galactic center — that was entirely undetectable in optical, ultraviolet, and radio observations.
- The possibility of two supermassive black holes orbiting each other just 0.1 parsecs apart raises urgent questions about galactic evolution, gravitational dynamics, and the origin of a high-energy neutrino traced to this nucleus in 2022.
- JWST cannot directly resolve two objects so close together at such distance, but it can map the motion of surrounding dust and gas — and those motions may betray whether one gravitational giant or two is driving the chaos.
- The telescope has also revealed vivid starburst regions, including a prominent ring of star formation encircling the core, painting a portrait of a galaxy simultaneously destroying and creating on a violent, continuous scale.
The Squid Galaxy — catalogued as M77 or NGC 1068 — presents a luminous face of sweeping dust lanes and glittering young stars. But beneath that surface lies something far stranger: a violent core, and possibly two supermassive black holes locked in orbit around each other.
Sitting roughly 35 million light-years from Earth, the galaxy has long been considered an ideal laboratory for studying active galactic nuclei. The obstacle has always been dust. Thick clouds shroud the galactic center, blocking visible light and leaving astronomers effectively blind to what drives the engine within. The James Webb Space Telescope was built for exactly this problem. Infrared radiation passes through dust that stops visible light cold, and JWST's near- and mid-infrared cameras have now revealed features of the Squid Galaxy that no prior observation could reach.
Most striking is a bar structure — a ribbon of stars, gas, and dust running across the galaxy's center — never seen before in any wavelength. The new images also clarify the environment around the galactic core, where mass equivalent to roughly 13 million Suns is concentrated. Evidence suggests two supermassive black holes may be orbiting each other at a separation of just 0.1 parsecs. JWST cannot resolve two objects so close together across tens of millions of light-years, but it can track how surrounding dust and gas move — and those motions will reveal whether one black hole or two is doing the stirring.
The infrared images also illuminate the galaxy's creative side: bright red starburst regions dot the spiral arms, and a prominent ring of star formation, several thousand light-years across, encircles the core itself. Meanwhile, a high-energy neutrino traced back to the galactic nucleus in 2022 suggests the Squid Galaxy may be one of only a handful of cosmic particle accelerators ever identified beyond the Milky Way — a place where matter is consumed at a rate of roughly 0.23 solar masses per year, generating conditions violent enough to launch particles toward the speed of light.
With each infrared observation, JWST adds another layer to a portrait that dust once made impossible. The bar structure, the possible binary black holes, the starburst ring, the neutrino source — together they suggest a galaxy operating at the outer edge of what physics permits, and a telescope finally capable of watching it happen.
The Squid Galaxy wears its beauty like a mask. Dust lanes sweep across its face in dramatic arcs, and pockets of newborn stars glitter along its spiral arms. But beneath that luminous surface lies something far stranger: a violent engine at the core, and possibly not just one but two supermassive black holes locked in orbit around each other.
The galaxy, formally catalogued as M77 or NGC 1068, sits about 35 million light-years from Earth—close enough and bright enough to make it an ideal laboratory for studying how active galactic nuclei behave. The problem has always been the dust. Thick clouds of it shroud the galactic center, blocking the visible light that would let astronomers see what's actually happening in there. Until now, peering into the Squid Galaxy's heart meant working blind.
The James Webb Space Telescope was built for exactly this kind of challenge. Where visible light gets scattered and absorbed by dust, infrared radiation passes straight through. Using JWST's near-infrared and mid-infrared cameras, astronomers have now seen features of the Squid Galaxy that were completely invisible in optical, ultraviolet, and radio observations. Most striking is a bar structure—a ribbon of stars, gas, and dust running across the galaxy's center—that had never been visible before. It's the kind of detail that changes how we understand a galaxy's architecture and dynamics.
The new images also cut through the dust to reveal the environment immediately surrounding the galactic core. The mass concentrated there weighs roughly 13 million times what our Sun does, but its exact nature remains uncertain. Recent evidence suggests that two supermassive black holes may be orbiting each other at the center, separated by just 0.1 parsecs. JWST's resolution, remarkable as it is, cannot separate two objects that close together from tens of millions of light-years away. But the telescope can do something almost as useful: it can track how dust and gas move around the galactic center, and those motions will reveal whether one black hole or two is doing the stirring.
The Squid Galaxy is a factory of creation as well as destruction. Scattered throughout the infrared images are bright red regions where new stars are being born. A particularly prominent ring of star formation circles the galactic center, a few thousand light-years in diameter. Astronomers call this a starburst ring, and they believe it formed naturally as the galaxy's own gravity concentrated gas in that zone. Additional starburst regions dot the spiral arms, evidence of a system in constant, violent flux.
There is one more piece of the puzzle. In 2022, scientists traced a high-energy neutrino—a ghost particle born only in the most extreme conditions—directly back to the Squid Galaxy's core. The galactic nucleus consumes material at a rate equivalent to about 0.23 solar masses per year, an enormous appetite that generates tremendous energy. That combination of extreme gravity, intense friction, and rapid consumption creates conditions hot and violent enough to accelerate particles to nearly the speed of light. If the Squid Galaxy is indeed a giant particle accelerator, it would be one of only a handful ever identified outside the Milky Way.
With infrared eyes, JWST is beginning to answer questions about the Squid Galaxy that have puzzled astronomers for decades. The bar structure, the dual black holes, the starburst ring, the neutrino source—each observation adds another layer to our understanding of how galaxies work at their most extreme. The dust that once hid these secrets is now transparent.

Why does dust matter so much? Can't we just look harder with visible light?
Dust doesn't just dim the light—it scatters it, bends it, breaks it apart. Visible light gets trapped. Infrared passes right through, like looking through fog with night-vision goggles. That's why JWST had to be built to see in infrared.
So the bar structure was always there, just invisible?
Exactly. It's not new. It's been there shaping how gas and stars move in that galaxy for millions of years. We just couldn't see it until now. That changes how we understand the whole system.
Two black holes orbiting each other—how is that even stable?
It's not stable forever. They're slowly spiraling toward each other, losing energy as they go. Eventually they'll merge. But on human timescales, they're locked in a tight dance.
Can JWST actually prove there are two?
Not by imaging them directly—they're too close together. But by watching how the gas and dust swirl around the center, we can infer what's causing the motion. The signature of two black holes would look different from one.
What about that neutrino from 2022? What does that tell us?
It tells us the galactic center is a particle accelerator. Neutrinos only form in the most violent, energetic places. Finding one traced back to the Squid Galaxy means something down there is reaching temperatures and energies we usually only see in supernovae or near black holes.
Is this galaxy unusual, or are we just seeing it more clearly now?
Both. The Squid Galaxy is close and bright and facing us head-on, which makes it ideal for study. But JWST is revealing that galaxies in general are more complex than we thought. We were missing whole structures because we couldn't see through the dust.
