article_snippet.sent: an exoplanet was discovered using a technique known as microlensing.
article_snippet.sent: The microlensing technique as a whole has yielded about 30 planet discoveries so far, with the farthest residing about 25,000 light-years away. '
article_snippet.sent: Microlensing experiments are already detecting planets from the solar neighborhood to almost the center of the Milky Way,' said co-author Andrew Gould of The Ohio State University, Columbus. '
article_snippet.sent: Microlensing complements other planet-hunting tools, such as the Kepler mission, which has found more than 1,000 planets closer to home.
article_snippet.sent: Of the 30 planets discovered with microlensing so far, roughly half cannot be pinned down to a precise location.
article_snippet.sent: Data from the microlensing event is seen here.  
article_snippet.sent: Using space telescopes to observe microlensing events is tricky.
article_snippet.sent: In the case of a planet, the duration of the microlensing event happened to be unusually long, about 150 days.
