How SETI is expanding its search for alien intelligence (exclusive)

To spot potential intelligent life out there in the great beyond, first you must cast a net wide by using an array of techniques and technologies. 

Any “fishing expedition” for E.T. includes close-in studies of life in extreme environments right here on Earth, to help us recognize any signatures we might find on Mars or deep diving through the icy shell of Jupiter’s moon, Europa. The search can also blend in the use of space-based telescopes to inspect Earth-like planets circling their home stars. Then there’s cupping a proverbial ear to the cosmos using radio telescopes to pick up any bustling interstellar civilization or perhaps look for far-off laser-pulsed communiqués from extraterrestrial homebodies.
