The first discovery of extraterrestrial life will almost certainly NOT be when it visits us, nor when we visit it. It won’t be when we see it’s stray TV signals. It’ll be in the excruciatingly faint changes in the color of alien sunsets glimpsed hundreds of light years away. Today we’re going to talk about the first such hint, why it's probably not aliens, and why there’s a tiny chance that it still might not not be aliens.
