Is Oumuamua An Alien Object?
In 2017, we spotted Oumuamua, an interstellar object on a tumbling trajectory
that took it into our solar system and around the sun. Oumuamua was traveling
exceptionally fast — twice the speed of the Voyager 1 probe. It slingshotted
around the Sun, briefly passed within range of Earth’s telescopes, and vanished
back into space. The speculation about it started in earnest when scientists
noticed it had slingshotted around the sun faster than should have been possible.
The likeliest explanation is that, like a comet, it lost mass as it went around
the Sun, increasing its velocity. We’ve been surprised by the trajectories of
objects in space before, with no aliens involved. Sometimes our calculations
are just slightly off. But researchers studying Oumuamua courted controversy
and attracted fascinated media attention when they mentioned that Oumuamua
could instead be artificial in origin.
