So say the "astro-boffins" apparently.

We find exoplanets when they transit their stars. How are we finding exo moons? When they transit their planets transitting their stars?

Probably when we're luckily aligned such that the planet and moon are visible against their parent star.

Yeah, I couldn't finish the article once I saw that.

I could have said "that shiatty Avatar movie," but I was making a prediction.

And you were being redundant.

I really wish I had the time to photoshop Xzibit looking into a telescope.

In a few billion years, Earth's moon may no longer be a moon.

/It's moving away from us at 1.5 inches a year -- at some point the barycenter (the center of mass of both bodies) will no longer be below the earth's surface, but move above it, at which point Earth/Moon will graduate to be a binary/double planet system instead.

This just in...

Some moons are planets.

Earth is a double planet system.

I'm guessing equipment and processing sensitivity are getting good enough to detect a transit pattern, or planet wobble.

Among other things, very entertainingly summarizes transitive photometry.
