Arizona State University astronomers reported this week that the strange 148-foot object that appears to be made of frozen nitrogen, just like the surface of Pluto and Neptune s largest moon Triton The study's authors, Alan Jackson and Steven Desch, think an impact knocked a chunk off an icy nitrogen-covered planet 500 million years ago and sent the piece tumbling out of its own star system, toward ours. “Everybody is interested in aliens, and it was inevitable that this first object outside the solar system would make people think of aliens,” Desch said in a statement. Given that Oumuamua is unlike comets and asteroids — and something not seen before — “we cannot assume ‘business as usual,’ as many scientists argue,” Loeb wrote in an email Wednesday.
