Unraveling the Mystery of Interstellar Object 'Oumuamua's Acceleration

A new study suggests that 'Oumuamua, the object that passed through our solar system in 2017, was a comet from another solar system. However, Harvard astronomer Avi Loeb, who has suggested that 'Oumuamua might be an alien spacecraft, has responded with a "correction" to the study, stating that the surface temperature of 'Oumuamua was miscalculated, and that it is still possible that 'Oumuamua is not a natural object. Loeb's new book, Interstellar, is due out in August 2023.
