The first clue to the origin of starlight happened as recently as 1899 radioactivity.

So, at the center there, that's actually where most of the starlight comes out from.

And yet, what we actually see is light that can't be explained by the starlight.

Then it has detectors on its back so it can sense how much starlight or moonlight is hitting its back.

That ancient dream that had always eluded the alchemists was achieved through these same theories that explained starlight and other ancient mysteries, and new, unexpected phenomena.

On bright nights when there is lots of starlight or moonlight that light can penetrate the depth of the water the squid lives in, since it's just in those couple feet of water.

And what we're looking for is the tiny dimming of light that is caused by a planet passing in front of one of these stars and blocking some of that starlight from getting to us.

But really, every measurement it makes is precious, because it's teaching us about the relationship between stars and planets, and how it's really the starlight that sets the stage for the formation of life in the universe.
