<p>How would we be able to detect Exomoons? We detect exoplanets by seeing if the light gets faint from a star, but could we really use the same method for determining if there is an exomoon around that exoplanet? Thanks for your thoughts and answers! </p>

Frankly, this shows lack of research effort.

I'm going to try to take a stab at answering this. With our current technologies, detecting exomoons can prove hard however there are various techniques being used today such as:

1. Analyzing data from the Kepler Spacecraft
2. Dynamic effects – the exomoon tugs the planet, which causes deviations in the times and durations of the host planet’s transits. This is similar to the radial velocity technique for detecting exoplanets. Source: [UniverseToday](http://www.universetoday.com/103238/the-hunt-for-exomoons-begins/)
3. Transit effects – the exomoon may transit the star immediately before or just after the planet does. This will cause an added dip in the observed light. See this video for a great demonstration.
