Harvard Astrophysicist Raises Concerns Over Interstellar Object 3I/ATLAS
Dr. Avi Loeb suggests NASA may be withholding information about the interstellar comet 3I/ATLAS, urging public vigilance ahead of its perihelion on October 29.
Harvard astrophysicist Dr. Avi Loeb has expressed concerns regarding the interstellar comet 3I/ATLAS, suggesting that NASA may be withholding critical information about the object. Discovered on July 1, 2025, by the ATLAS telescope system, 3I/ATLAS is the third confirmed interstellar object to enter our solar system, following 'Oumuamua in 2017 and Comet Borisov in 2019.
Dr. Loeb has urged the public to "take vacations before October 29," the date when 3I/ATLAS is expected to reach its closest point to the Sun, known as perihelion. He claims that NASA has not been transparent about the comet's characteristics and trajectory. In a recent interview, Dr. Loeb stated, "We want to see the data from the scientists."
Observations from the James Webb Space Telescope have revealed that 3I/ATLAS's coma is unusually rich in carbon dioxide relative to water, suggesting it may have formed near the CO₂ ice line in a distant protoplanetary disk or been exposed to substantial radiation. Additionally, the comet's trajectory is aligned within 5 degrees of the ecliptic plane, a statistically unusual occurrence for interstellar objects.
Despite these anomalies, other astronomers have conducted simulations indicating that 3I/ATLAS likely originated from the Milky Way's thin disk and may be up to 10 billion years old. They found no evidence of artificial interference. NASA has also stated that 3I/ATLAS poses no threat to Earth, as it will pass safely through the inner solar system.
The scientific community remains divided over Dr. Loeb's assertions. While some dismiss his warnings as sensationalism, others acknowledge that 3I/ATLAS presents a unique opportunity to study materials from other star systems. As the comet approaches its perihelion on October 29, astronomers worldwide are closely monitoring its behavior to gather more data and address the questions raised.
