“What's most surprising is that we've never seen interstellar objects pass through (our solar system) before.”  - Karen Meech, Ph.D., Astronomer, Institute for Astronomy, University of Hawaii, Honolulu

“Unexpectedly, we found that Oumuamua was not slowing down as fast as it should have under gravitational forces alone.”
- Marco Micheli, Ph.D., Astronomer, European Space Agency, and Author of Oumuamua paper, June 27, 2018,  Nature
