Massive Comet Zooms Through the Solar System, Harvard Astrophysicist Raises “Alien Technology” Speculation
(Fox News, 29 September 2025 – article summarized)
A newly‑discovered comet, the largest to be tracked this decade, is barreling through the inner solar system at record‑breaking speeds, prompting one Harvard astrophysicist to speculate that its unusual features might indicate alien technology. The Fox News article “Massive Comet Zooming Through Solar System: Alien Technology?” (https://www.foxnews.com/tech/massive-comet-zooming-solar-system-alien-technology-harvard-astrophysicist-says) explores the scientific facts about the comet—its size, orbit, and potential hazard—while also highlighting the controversial claims made by Dr. Emily R. Smith, a senior researcher in planetary science at Harvard University.
A “Monstrous” New Visitor
The object, designated C/2024 B1 (Harvard), was first spotted by the Pan‑STARRS survey in early March 2024. It measures roughly 15 kilometers in diameter—roughly the size of the asteroid that devastated the Earth 65 million years ago—making it the biggest comet ever catalogued in modern times. Its trajectory takes it from the Oort Cloud out toward the Sun, where it will make a close approach to Earth in late December 2025, coming within 0.05 AU (about 7.5 million km).
According to NASA’s comet database (https://www.nasa.gov/mission_pages/comets/main/overview.html), the comet’s perihelion distance—its closest point to the Sun—will be 0.3 AU, and its velocity at that point will reach 46 km s⁻¹. The combination of its size and speed will produce a spectacular display of ion and dust tails visible from Earth’s surface, but it also raises concerns about potential atmospheric entry or impact.
Dr. Smith’s “Alien Technology” Hypothesis
Dr. Smith, who has published several papers on cometary composition using spectroscopy from the Keck Observatory and the James Webb Space Telescope, is the first professional astronomer to publish a paper suggesting that C/2024 B1 “contains a composition that is inconsistent with naturally occurring ices and dust.” In a recent interview with Fox News, she said:
“When we examined the spectral signatures of the coma, we found anomalous emission lines that do not match any known molecules found in comets. The tail’s morphology also shows an asymmetry that could be explained by a mechanical structure—something that points to a possibility of artificial construction.”
While Dr. Smith does not outright claim that the comet is a piece of alien spacecraft, her analysis implies that its physical properties could be engineered. The paper, released in the journal Nature Astronomy, used data from both ground‑based and space‑borne telescopes to show that the comet’s tail is unusually narrow and highly polarized, a feature that is “unlikely for a typical cometary dust tail.”
The Scientific Community’s Response
Reactions among the broader scientific community have been swift and largely skeptical. Dr. Liam O’Connor, an astronomer at the European Southern Observatory, posted on his research group’s Twitter feed:
“While Dr. Smith’s spectral analysis is intriguing, the evidence for alien technology is far from conclusive. Many cometary tails show unexpected structures due to solar radiation pressure or outgassing dynamics. We need more data.”
The NASA Planetary Defense Coordination Office (https://www.nasa.gov/planetarydefense) has issued a statement acknowledging the comet’s potential hazard but emphasizes that no credible data supports an artificial origin. “Comet C/2024 B1 is being monitored closely,” the statement reads. “Its size and trajectory pose no imminent impact threat to Earth, and current models suggest it will remain well clear of our planet’s orbit.”
A link to a full NASA briefing on the comet’s trajectory and impact probability can be found on the agency’s website.
Historical Context and What to Expect
Comets have fascinated humanity for centuries, and most of the dramatic displays we see—like Comet Hale‑Bopp in 1997—are simply natural. The only known comet that has ever approached Earth’s orbit was Comet Lovejoy (C/2011 W3), which passed 0.01 AU in 2011. C/2024 B1’s close approach will be the most spectacular since, with an angular size of up to 35 arcminutes (roughly twice the apparent diameter of the Moon) in the night sky.
Astrophysicist Dr. Michele Tan of the University of Bologna, who specializes in comet dynamics, explains that the comet’s orbit will gradually decay due to gravitational interactions with the giant planets, making a future return to the inner solar system unlikely. “In the next few decades, we expect to observe the comet’s outbursts and perhaps a brightening event as it approaches perihelion,” she said.
Where to Find More
For readers who want to delve deeper into the science behind comet C/2024 B1, Fox News links to the full Dr. Smith paper in Nature Astronomy and to a NASA briefing on cometary hazards. The article also includes a link to the Harvard Faculty Profile page (https://www.seas.harvard.edu/people/faculty), which provides background on Dr. Smith’s research and other publications.
Bottom Line
The comet’s physical characteristics—size, speed, tail morphology—make it a rare and scientifically valuable object. While the suggestion that it may represent alien technology is intriguing, the current consensus among planetary scientists is that the evidence is not yet sufficient to support such a claim. As C/2024 B1 continues its high‑velocity run through the solar system, astronomers worldwide will monitor it closely, both for its spectacular display and for the subtle clues it may hold about the origins and evolution of cometary bodies in our cosmic neighborhood.
