Astronomers today confirmed that an asteroid first spotted zipping through our solar system last month came from another star system. 'Oumuamua — Hawaiian for "a messenger from afar arriving first" — is one of the most elongated cosmic objects known to date.

Why it matters: 'Oumuamua's bizarre shape is unlike any other asteroid seen yet, and could "provide new clues regarding into how other solar systems formed," according to a NASA press release.
