Astrophysicist Avi Loeb says the Moon is slowly moving away from Earth—about one inch per year—so in roughly 600 million years, total solar eclipses will no longer occur as the Moon will no longer fully cover the Sun when viewed from Earth; a recent eclipse was visible in parts of Europe.
Harvard astronomer Avi Loeb and colleagues speculate that 1998 KY26—the rapidly spinning object Hayabusa2 is set to study in 2031—could be a long‑lost Soviet spacecraft (Phobos 1) rather than a natural asteroid. The idea, based on suggested orbital similarities and size, is highly speculative and not yet peer‑reviewed; it aims to broaden the observational data considered when judging solar‑system objects, with Hayabusa2’s observations expected to help resolve the object's true origin.
In 2017, the first confirmed interstellar object, Oumuamua, passed through the Solar System on a hyperbolic path and showed a tiny non-gravitational push without a visible tail. Natural explanations (e.g., venting hydrogen or nitrogen ices) exist, and Avi Loeb's artificial-origin idea remains controversial; since then Borisov and ATLAS behaved like comets, but Oumuamua remains an unresolved puzzle, underscoring data limits and the hope that Rubin Observatory will help settle what it could not.
Harvard astronomer Avi Loeb suggests the interstellar visitor 3I/ATLAS could have seeded life across the Solar System via natural panspermia or even directed panspermia; while controversial, he argues that ice-encased life might survive transit and proposes intercepting future interstellar objects to test for extrasolar biology and compare it with Earth life.
Harvard astronomer Avi Loeb proposes that the interstellar visitor 3I/ATLAS could have seeded life in the Solar System, either by ice-embedded life released as it traveled or through directed panspermia by an advanced civilization; while the idea is controversial and debated, Loeb argues that intercepting such objects could help determine if extrasolar life resembles Earth life, a notion that would have profound implications for our understanding of life's origins.
Harvard astrophysicist Avi Loeb challenges NASA’s claim that a cone-shaped feature photographed by the Curiosity rover in Gale Crater is merely a rock, arguing the object could be about 20 cm and may be debris, while NASA says it’s a small (about 1 cm) wind-sculpted formation and suggests pareidolia; Loeb has urged NASA to show another similar rock in Curiosity images to back its interpretation.
Recent observations suggest that interstellar comet 3I/ATLAS has not exploded or broken into pieces, contrary to some claims, and most scientists agree it is a natural object from beyond our solar system, despite speculation about its origins.
Harvard scientist Avi Loeb raises concerns about the interstellar comet 3I/ATLAS, noting its lack of a typical cometary tail and anomalies in its behavior, leading him to speculate it could be an artificial object or extraterrestrial technology, though NASA dismisses these claims.
Recent images of the interstellar object 3I/ATLAS taken after its perihelion show a lack of a visible cometary tail despite signs of significant mass loss and non-gravitational acceleration, raising questions about its nature and composition, with comparisons to typical comets like Lemmon.
Harvard astronomer Avi Loeb hypothesizes that the quasi-satellite 2025 PN7, recently captured by Earth, may be a remnant of the Soviet Union's Zond 1 mission from 1964, suggesting it could be an ancient spacecraft or artifact from a long-dead civilization, with further spectral analysis needed to test this theory.
Harvard astronomer Avi Loeb hypothesizes that the quasi-satellite 2025 PN7, recently captured by Earth, may be a remnant of the Soviet Union's Zond 1 mission from 1964, suggesting it could be an ancient human-made artifact or relic from a long-dead civilization, with further spectral analysis needed to test this theory.
Harvard astrophysicist Avi Loeb warns that if evidence of extraterrestrial origin for 3I/ATLAS is confirmed around 29 October, it could lead to societal upheaval and a metaphorical 'stock market crash' due to shock and panic, emphasizing the need for transparency and preparedness.
Interstellar comet 3I/ATLAS is approaching its closest point to the Sun, with some scientists, including Avi Loeb, suggesting it may have an artificial origin due to its unusual characteristics, such as a potential nickel alloy composition and atypical jet behavior. The comet's behavior as it nears the Sun could change dramatically, and high-resolution images are eagerly awaited, though some data remains undisclosed due to government shutdowns.
Avi Loeb attended a NASCAR race where a driver featured an 'interstellar car' inspired by the interstellar object 3I/ATLAS, highlighting the potential for future interstellar travel and the possibility of detecting interstellar objects entering our solar system. The event also included discussions on physics, AI in racing, and the nature of interstellar objects, with Loeb emphasizing the importance of open scientific inquiry.
A Harvard astrophysicist warns that an interstellar object, 3I/ATLAS, may be artificial and urges the public to take vacations before October 29, citing potential concealment by NASA and unusual features of the object, though scientists suggest it is likely a natural relic from space.
