The Mystery of 3I/ATLAS: An Alien Spacecraft or a Natural Comet?
In just under a month, an interstellar object named 3I/ATLAS is set to make its closest approach to Earth, coming within a mere 170 million miles of our planet. But here's where it gets controversial: Harvard astronomer Avi Loeb, a champion of the idea that 3I/ATLAS could be an alien spacecraft, has noticed something intriguing.
Three months after its Earth flyby, 3I/ATLAS is expected to venture even closer to Jupiter, following a highly eccentric path through our solar system. Loeb points out that recent non-gravitational acceleration has pushed this object towards a peculiar region of Jupiter's orbit—its Hill radius.
Jupiter's Hill radius is a boundary within which the gas giant can maintain control over an object's orbit, preventing it from being stolen by the Sun. Loeb suggests that if 3I/ATLAS is indeed an alien spacecraft, it might be passing through Jupiter's Hill radius to deploy what he calls "technological devices."
"If we discover technological satellites orbiting Jupiter that we didn't send, it would indicate that Jupiter is of interest to an extraterrestrial civilization," Loeb writes.
However, not everyone is convinced, including NASA. With substantial evidence suggesting that the mysterious visitor is a comet made of ice and dust, NASA associate administrator Amit Kshatriya has dismissed Loeb's theory, much to his frustration.
During its closest approach to the Sun last month, 3I/ATLAS experienced a push in the form of non-gravitational acceleration. While a conventional explanation might attribute this to the Sun's radiation heating the object and causing it to lose mass, Loeb proposes a more intriguing possibility: "it could be the technological signature of an internal engine."
This extra push will allow 3I/ATLAS to come within approximately 53 million miles of Jupiter on March 16, a distance that just so happens to be within 160,000 miles of the planet's Hill radius.
"In other words, the non-gravitational acceleration introduced a small course correction of exactly the magnitude needed to bring the minimum distance of 3I/ATLAS from Jupiter to the value of Jupiter's Hill radius," Loeb explains. "3I/ATLAS would have missed the edge of the Hill sphere otherwise."
Loeb further suggests that 3I/ATLAS' non-gravitational acceleration was finely tuned with the help of thrusters to reach the radius of Jupiter's gravitational influence. He urges scientists to remain open-minded and not jump to conclusions, arguing that the discovery of "technological satellites" orbiting Jupiter, rather than Earth, could be a humbling experience.
"Perhaps this is because the human species arrived late to the party—only a few million years ago—whereas Jupiter, the biggest planet in our solar system, was visible to the senders of 3I/ATLAS when their mission was launched billions of years ago," Loeb concludes.
So, is 3I/ATLAS an alien spacecraft or a natural comet? Only time and further investigation will tell. Loeb encourages the NASA Juno spacecraft, currently orbiting Jupiter, to take a closer look at 3I/ATLAS this spring.
