Astronomers scan hundreds of stars for 'anomalous transits'

Telescopes have been collecting copious amounts of data on exoplanets in recent years. One of the most common datasets tracks what are known as transits, when an exoplanet crosses in front of its host star and dims the star's light slightly as it does so. The majority of exoplanets have been found this way, but other interesting details might be hidden in the data.
