Harvard scientist continues to claim Oumuamua is an alien probe directed to Earth

Omu Amua, an interstellar object, was first observed in October 2017 using the Pan Stars telescope in Hawaii. It has a unique shape and acceleration, sparking debate about its nature. Some scientists consider it an asteroid or comet, while others suggest extraterrestrial origins. A paper by Abraham Loeb proposes it might be a space probe powered by solar sail technology. The object's reddish color could be due to interstellar dust, and its trajectory might indicate it is an alien probe intentionally passing by.

What unusual characteristics of Oumuamua have led to speculation among astronomers?
