Unnamed Moons: Worlds That May Be Hiding in a Planet's Shadow
When an exoplanet passes in front of its star, a telescope sees a tiny dip in light. Much of the search for other worlds begins with that pulse. But if the planet has a moon, the moon may pass ahead, trail behind, merge into the planet's shadow, or tug the planet slightly off schedule. The signal is so small that it may be noise, stellar activity, another planet, or a bad model. An exomoon is therefore a difficult...

The signal is so small that it may be noise, stellar activity, another planet, or a bad model. An exomoon is therefore a difficult dossier: what we seek does not appear as an object, but as a slight mismatch in time.
