Harvard physicist suggests interstellar object hurdling through our solar system is alien aircraft

A Harvard scientist has suggested that an interstellar object passing through the solar system might be a nuclear-powered alien spaceship.

Most astronomers believe the object, dubbed 3I/ATLAS, is likely a comet, according to Futurism. But Harvard University astronomer Avi Loeb doubts this theory because of the light coming from the object.

In a blog post published earlier this week, he noted how an image of the object obtained by the Hubble Space Telescope last month “shows a glow of light, likely from a coma, ahead of” 3I/ATLAS.

“A coma is the hazy and luminous cloud that surrounds the nucleus of a comet,” Futurism notes.

The problem, Loeb argued, is that “[t]here is no evidence for a bright cometary tail in the opposite direction.”

The blog that started it all…

Other astronomers believe the glow of light is the result of dust evaporating from the object’s sun-facing side.

But Loeb doesn’t buy this theory. He also dismissed theories that the light might be from a black hole or supernova.

“I first calculated that a primordial black hole with a Hawking temperature of 1,000 degrees Kelvin would produce only 20 nanowatts of power, clearly insufficient to power 3I/ATLAS,” he wrote.

“A natural nuclear source could be a rare fragment from the core of a nearby supernova that is rich in radioactive material. This possibility is highly unlikely, given the scarce reservoir of radioactive elements in interstellar space,” he added.

He then speculated that the object might be generating “its own light.”

“Alternatively, 3I/ATLAS could be a spacecraft powered by nuclear energy, and the dust emitted from its frontal surface might be from dirt that accumulated on its surface during its interstellar travel,” he wrote. “This cannot be ruled out, but requires better evidence to be viable.”

He added that 3I/ATLAS’s “fine-tuned trajectory” (flight path) also seems to jibe with his theory.

“This puzzle is alleviated if the trajectory of 3I/ATLAS was designed to target the inner Solar system, namely it is not a rock but a technological object,” he explained in another blog post.

“This interpretation gains traction from the fact that the path of 3I/ATLAS is aligned with the orbital plane of the planets around the Sun, an unlikely coincidence at the level of ~0.2%,” he continued.

Loeb also made the case that 3I/ATLAS could be of “comparable size” to previous interstellar objects that have recently passed through the solar system, including 1I/ʻOumuamua and or 2I/Borisov.

Recall that when 1I/ʻOumuamua was detected in 2017, many suspected it too was an alien spacecraft:

Some scientists believe that ‘Oumuamua — the first interstellar object ever seen in our solar system — might not be a natural asteroid at all… but a massive alien spacecraft using solar sails to search for life.

The good news is that, according to Futurism, “3I/ATLAS will come within spitting distance — at least in astronomical terms — of Mars this fall, giving us a tantalizing opportunity to have a first-hand look.”

Loeb has, for his part, suggested that NASA use its Mars Reconnaissance Orbiter to study the object once it arrives. Amazingly, NASA is reportedly game.

“This morning, I encouraged the HiRISE team to use their camera during the first week of October 2025 in order to gather new data on 3I/ATLAS,” Loeb revealed in his blog. “They responded favorably.”

Appearing this Wednesday on NewsNation, Loeb again drew attention to 3I/ATLAS’s strange trajectory.

I/ATLAS may be nuclear-powered,

Avi Loeb, the Harvard theoretical physicist who has drawn attention for suggesting comet 3I/ATLAS may be alien-made, is sharing a new thought:

“The timing of its arrival is perfect for that, with a likelihood of one in 20,000,” he said. “We should observe it. It doesn’t look like it’s a random occurrence.”
