A NASA-backed planetary defense group has reportedly begun efforts to pinpoint comet 3I/ATLAS after it was observed emitting an alloy not seen in nature and exhibiting other strange behaviors.

They’re battening down the heavenly hatches.
A NASA-coordinated group has reportedly begun efforts to observe Comet 3I/ATLAS after it was seen emitting a never-before-seen alloy and exhibiting other strange behaviors.
The cosmic anomaly — a Manhattan-size interstellar object that potentially has alien tech — has been added to the list of threats by the
International Asteroid Warning Network, a worldwide coalition of space experts who collaborate to detect and monitor potentially hazardous asteroids and Near-Earth Objects to assess their potential impacts to our planet.
3I/ATLAS prompted an IAWN campaign to hone members’ detection skills and prep Earth for a potential threat from beyond.
The celestial object, which was first noticed on July 1, has notably displayed a host of unusual characteristics that seemed to defy normal comet behavior.

These included an anti-tail — a jet of particles that points toward the sun instead of away from it, as is typical.
The comet also emitted a plume that contained 4 grams of nickel per second with no evidence of iron — a phenomenon unheard of in comets.
IAWN will be conducting a "comet campaign" from Nov. 27 through Jan. 27 to refine methods for pinpointing the exact location of Comet 3I/ATLAS (pictured).
The alloy — nickel tetracarbonyl — has previously been witnessed only in human manufacturing, Harvard astrophysicist Avi Loeb told The Post.
Loeb also mentioned the object’s non-gravitational acceleration and anomalous trajectory that will bring it suspiciously close to Jupiter, Venus and Mars, which he pointed out — in a somewhat far-fetched paper — could indicate that it was an alien probe sent to do recon on Earth.
IAWN will be conducting a “comet campaign” from Nov. 27 through Jan. 27 to refine methods for pinpointing ATLAS’ exact location.
“To prepare for the campaign, we will hold a workshop on techniques to correctly measure comet astrometry (a transformation without a change to a figure’s shape or size, such as rotation or reflection),” they wrote.
Needless to say, the development had X users quaking in their boots. “They’re calling it ‘a test of improved astrometry methods,'” fretted one. “In other words, the object isn’t behaving like it should.”
Thankfully, IAWN is currently treating the drill not like a call to enact interplanetary defenses, but rather a guide for stargazers hoping to get a better view.
Coincidentally, 3I/ATLAS is just days away from making its closest approach to the sun and slipping out of view.
Loeb postulated that this “maneuver” could be proof that the object is a spacecraft that’s using the gravity of the solar star to change speed and trajectory.
Ultimately, the fact that IAWN activated its “comet campaign” indicates to the scientist that 3I/ATLAS, which astronomers concluded could measure 28 miles across, might not be a harmless comet.
“If 3I/ATLAS is a massive mothership, it will likely continue along its original gravitational path and ultimately exit the Solar system,” Loeb shared in a
Sunday blog post.
