If we hope to find an Earth-like world around another star, we must first be sure we would recognize...
...experiment was surprisingly inexpensive: The whole set-up only cost about $15,000 - next to nothing for a piece of groundbreaking astronomical research. "Earthshine is such a simple idea that we have known about for such a long time," says Langford, "but it makes looking at Earth as a 'prototype' Earth-like planet so easy! An amateur astronomer could definitely take this data...
