Oumuamua and the Emerging Study of Interstellar Objects
To the point
1I/'Oumuamua is described as the first confirmed interstellar visitor, with a pancake-like shape, a fast hyperbolic path, and mysterious nongravitational acceleration that spurred competing explanations from outgassing to a possible solar sail, discovered by Pan-STARRS (Rob Weryk) in Hawaii, with expert input from David Trilling and Avi Loeb about what such visitors mean for other planetary systems, and with updates on 3I/ATLAS and the role of future facilities like Rubin Observatory and NASA's Roman Space Telescope.
