Fresh research has suggested a very violent origin story for the rocky,
cigar-shaped, interstellar visitor known as ‘Oumuamua that has wandered
into our solar system in recent years.

The mysterious object was spotted hurtling through our galactic
neighborhood in October 2017 and was given its unusual name after the
Hawaiian word for messenger.

Astronomers quickly realized that the object had several peculiar
qualities, including its highly elongated shape, its apparent ability to
accelerate without the help of gravity and its lack of an envelope of gas
or dust.

The odd combination of characteristics led some Harvard scientists to
propose that ‘Oumuamua could be an alien spacecraft and suggested that
researchers remain open to the idea.

However, the new study has posited a natural explanation for all of the
object’s eccentricities. It suggests that ‘Oumuamua is an *“active
asteroid” *that formed from a body that was ripped apart by its parent star
and then fired into space.

*“We showed that ‘Oumuamua-like interstellar objects can be produced
through extensive tidal fragmentation during close encounters of their
parent bodies with their host stars, and then ejected into interstellar
space,”* explained co-author Douglas Lin of the University of California,
Santa Cruz.

Writing in the journal Nature Astronomy, the boffins reported that this
violent birth explains ‘Oumuamua’s mysterious features, including its
shape, color and tumbling motion. They add that their findings again
undermine <https://www.rt.com/news/443358-oumuamua-theory-aliens-harvard/> the
much-publicized alien spacecraft theory.
