In problem solving, two heads are often better than one. So astronomers hope that two telescopes combined will be better than one as they try to detect planets outside our solar system .
Astronomers hope to use it for detecting habitable, Earth-like planets orbiting other stars.
Interferometry exploits the physical principle known as interference. When two waves of the same frequency and phase interact with each other, they can either interfere with one another constructively or destructively. For example, constructive interference occurs when a wave approaches a sea wall and hits a similar returning wave. The two waves suddenly combine into a much larger, more powerful wave than either one was individually. In the Keck scheme, the idea is to combine light waves from Keck I and II in constructive interference.
