New theory may explain how mystery space object Oumuamua came into being: astronomers

Omuamua, an interstellar object, has puzzled scientists with its unusual shape and unexplained acceleration. Discovered by the Pan Stars Observatory in Hawaii in 2017, its name means 'a messenger from afar arriving first.' A study suggests that tidal forces from a host star may have fragmented its parent body, forming Omuamua's elongated shape. The object's dry surface contrasts with expectations of icy interstellar objects, possibly due to intense heat near the star. As Omuamua travels through the solar system, trapped water ice may vaporize, providing thrust and causing its gravity-defying acceleration.
