Observation of an exoplanet with interferometry

Optical interferometry combines the light of multiple telescopes to perform the work of a single, much larger telescope. This is possible due to the interaction of light waves, also called interference. Their interaction can be used to cancel out the blinding glare of bright stars or to measure distances and angles precisely.
