These Giant Radio Telescopes Tune in to the Stars

The visible light comprises a minuscule fraction of the entire electromagnetic spectrum. Radio telescopes allow us to observe what cannot be seen, like microwave background radiation—the echo of the Big Bang. Our friends at Oobject have assembled 18 of the most expansive intergalactic listening stations.
