Is that cigar-shaped, fast-moving interstellar object a spaceship? Almost certainly not, but Breakthrough Listen will check just to make sure.

The Breakthrough Listen campaign, which checks celestial targets for radio signals from intelligent civilizations, will turn the Green Bank Telescope in West Virginia toward the object, known as ‘Oumuamua, starting Wednesday.

Scientists will check for emissions across four radio bands from 1 to 12 GHz. The first phase of observations will take up 10 hours, divided into four key time periods based on ‘Oumuamua’s period of rotation.
