Image: NASA, ESA, CSA, STScI; Image Processing: A. Pagan (STScI) This is a sparkling scene of star birth captured by NASA’s James Webb Space Telescope. What appears to be a craggy, starlit mountaintop kissed by wispy clouds is actually a cosmic dust-scape being eaten away by the blistering winds and radiation of nearby, massive, infant stars.
Called Pismis 24, this young star cluster resides in the core of the nearby Lobster Nebula, approximately 5,500 light-years from Earth in the constellation Scorpius. Home to a vibrant stellar nursery and one of the closest sites of massive star birth, Pismis 24 provides rare insight into large and massive stars. Its proximity makes this region one of the best places to explore the properties of hot young stars and how they evolve.
At the heart of this glittering cluster is the brilliant Pismis 24-1. It is at the center of a clump of stars above the jagged orange peaks, and the tallest spire is pointing directly toward it. Pismis 24-1 appears as a gigantic single star, and it was once thought to be the most massive known star. Scientists have since learned that it is composed of at least two stars, though they cannot be resolved in this image. At 74 and 66 solar masses, respectively, the two known stars are still among the most massive and luminous stars ever seen.

Webb captured this sparkling scene of star birth in Pismis 24, a young star cluster about 5,500 light-years from Earth in the constellation Scorpius. This region is one of the best places to explore the properties of hot young stars and how they evolve. Image: NASA, ESA, CSA, STScI; Image Processing: A. Pagan (STScI) Captured in infrared light by Webb’s NIRCam (Near-Infrared Camera), this image reveals thousands of jewel-like stars of varying sizes and colors. The largest and most brilliant ones with the six-point diffraction spikes are the most massive stars in the cluster. Hundreds to thousands of smaller members of the cluster appear as white, yellow, and red, depending on their stellar type and the amount of dust enshrouding them. Webb also shows us tens of thousands of stars behind the cluster that are part of the Milky Way galaxy.
Super-hot, infant stars –some almost 8 times the temperature of the Sun – blast out scorching radiation and punishing winds that are sculpting a cavity into the wall of the star-forming nebula. That nebula extends far beyond NIRCam’s field of view. Only small portions of it are visible at the bottom and top right of the image. Streamers of hot, ionized gas flow off the ridges of the nebula, and wispy veils of gas and dust, illuminated by starlight, float around its towering peaks.
Dramatic spires jut from the glowing wall of gas, resisting the relentless radiation and winds. They are like fingers pointing toward the hot, young stars that have sculpted them. The fierce forces shaping and compressing these spires cause new stars to form within them. The tallest spire spans about 5.4 light-years from its tip to the bottom of the image. More than 200 of our solar systems out to Neptune’s orbit could fit into the width its tip, which is 0.14 lightyears.
In this image, the color cyan indicates hot or ionized hydrogen gas being heated up by the massive young stars. Dust molecules similar to smoke here on Earth are represented in orange. Red signifies cooler, denser molecular hydrogen. The darker the red, the denser the gas. Black denotes the densest gas, which is not emitting light. The wispy white features are dust and gas that are scattering starlight.

Everything we know about 3I/ATLAS to date:
On July 1, 2025, the Asteroid Terrestrial-impact Last Alert System (ATLAS) station at Río Hurtado, Chile, detected something extraordinary: a fast-moving object flagged with the provisional designation A11pl3Z, later named 3I/ATLAS, also cataloged as C/2025 N1 (ATLAS).
At first glance, it was classified as a comet. But almost immediately, astronomers realized that this visitor was anything but ordinary.
3I/ATLAS imaged by the James Webb Space Telescope's NIRSpec on 6 August 2025.
Why 3I/ATLAS is different.
1. Interstellar Origins Like ʻOumuamua (1I/2017 U1) and Borisov (2I/2019 Q4) before it, 3I/ATLAS is only the third confirmed interstellar object to enter our solar system. Its steep hyperbolic orbit—with an eccentricity greater than 1.02—proves it is not gravitationally bound to the Sun.
2. A Composition Unlike Any Comet Most comets are rich in water ice. Not 3I/ATLAS. Spectroscopic analysis from both the Hubble Space Telescope and James Webb Space Telescope (JWST) revealed it is dominated by carbon dioxide with one of the highest CO₂-to-water ratios ever measured. This makes it chemically alien compared to the comets that formed in our own solar system.
3. A Tail That Breaks the Rules Comets typically sprout tails pointing away from the Sun, driven by sublimating ice. 3I/ATLAS, however, displays a dust plume angled toward the Sun—a tail in the “wrong” direction. This phenomenon has never been observed in a natural comet and suggests either unusual physics or engineered behavior.
4. Perfectly Aligned Trajectory Instead of cutting randomly across the solar system, 3I/ATLAS travels almost exactly along the ecliptic plane, the flat orbital path where Earth, Mars, and most of the planets reside. Statistically, the odds of a random interstellar object aligning this precisely are less than 0.005%.
5. Unexplained Acceleration Data from radar tracking and JWST confirm subtle but persistent non-gravitational acceleration. Normally, such changes are explained by outgassing jets. Yet Webb detects no coma, no jets, no thermal signature to explain the push. Instead, the acceleration resembles controlled propulsion, similar to how an ion engine expels dust or gas for thrust.
6. Forward-Facing Glow: Instead of a tail behind it, 3I/ATLAS shines with a glow ahead of its motion, almost as if it were illuminating its path.
7. Stabilized Rotation: Unlike natural tumbling comets, it appears to maintain attitude control, consistent with artificial stabilization.
8. Speculations of nuclear propulsion: Harvard astrophysicist Avi Loeb, already known for his bold ʻOumuamua interpretations, has highlighted its non-gravitational acceleration and trajectory. He even speculated that 3I/ATLAS might be nuclear-powered technology, perhaps venting dust as thrust.
9. 3I/ATLAS will not simply zip past and leave. Its calculated path takes it past several key planets: Venus flyby – August 2025 Mars encounter – September 2025 Jupiter flyby – late 2026
Tilted view of 3I/ATLAS's trajectory through the Solar System, with orbits and positions of planets shown. Such a sequence of planetary passes looks less like coincidence and more like a deliberate survey trajectory.
Finally, on October 30, 2025, the object will reach perihelion, its closest approach to the Sun. Crucially, at that moment it will be hidden directly behind the Sun from Earth’s perspective, a perfect opportunity for a stealth maneuver if it is indeed under intelligent control.
10. And the latest news on this object is that 3I/ATLAS shows signs of alien electroplating. Astronomers using the Very Large Telescope (VLT) in Chile have detected something never before seen in a natural comet, a plume of pure nickel gas, laced with cyanide, but completely lacking iron.
This is not how comets behave. In every known case, nickel and iron are paired together in space rocks, asteroids, and cosmic debris. The absence of iron in 3I/ATLAS makes it impossible to explain through natural processes.
The nickel-cyanide combination looks eerily familiar to something we know from human technology: nickel-cyanide electroplating. This industrial process is used to coat and protect metals like iron, creating a corrosion-resistant shell. When heated, such a coating releases nickel vapor and cyanide gas, the exact chemical fingerprint astronomers now see venting from 3I/ATLAS.
Renowned astrophysicist Avi Loeb has already highlighted this bizarre discovery, stressing that the nickel-only signature matches industrial alloy production rather than anything we’d expect from natural comet chemistry.
Pure nickel without iron: impossible in natural comets. Nickel + cyanide plume: matches electroplated coatings. Artificial signature: hallmark of industrial processes.
Putting it all together, so far: It is an interstellar visitor on a hyperbolic escape path. It has a carbon dioxide–dominated composition, nearly devoid of water. It has a dust plume points toward the Sun, breaking cometary rules. It has a trajectory which is perfectly aligned with the ecliptic plane. It shows mysterious acceleration without visible outgassing. It exhibits a forward glow, possible radio emissions, and signs of stabilization. It will perform planetary flybys. It probably has nuclear propulsion. It has an electroplated shell.
Mainstream astronomers remain cautious, still labeling 3I/ATLAS as a comet, but with mounting evidence, we may be staring at the first tangible proof of alien technology crossing our solar system, a probe from another civilization on a reconnaissance mission, silently mapping habitable worlds before making contact.View the full article

On Aug. 7 and 8, NASA’s Nancy Grace Roman Space Telescope team assessed the observatory’s solar panels and a visor-like sunshade called the deployable aperture cover — two components that will be stowed for launch and unfold in space. Engineers confirmed their successful operation during a closely monitored sequence in simulated space-like conditions. On the first day, Roman’s four outer solar panels were deployed one at a time, each unfolding over 30 seconds with 30-second pauses between them. The visor followed in a separate test the next day. These assessments help ensure Roman will perform as expected in space. Roman is slated to launch no later than May 2027, with the team working toward a potential early launch as soon as fall 2026.
