I'm not saying it's aliens

Ugh, another dark and dreary day, no sign of the sun and unremittingly damp. :-P

Here's another very cool science story, this time from Haaretz. You guys remember 'Oumuamua from a couple of years ago? The cosmic object that came ambling through our solar system, and everybody said "Wtf?" Well, the head of Harvard University's astronomy department thinks it was a spaceship. Specifically, a solar sail.

"The current propulsion technology doesn’t offer us the possibility to chase after 'Oumuamua. The visitor comes for dinner, goes out into the street and disappears in the dark. It’s possible we will never know what it was looking for.”

It's a really interesting article. :D
