Physics Colloquium — John Bahcall Memorial Lecture

Abstarct:

50 Years after it was first proposed as a planet search technique, microlensing has developed into a powerful probe of planet populations that are inaccessible to other methods.  Microlensing has already given us the first frequency measurements of free-floating planets, and of bound planets beyond the snow line, as well as the first true solar system analogs, i.e., multi-giant systems beyond the snow line. Even its detections of more prosaic binaries have yielded startling results.  Microlensing planet searches are now entering a new era of "second generation surveys", in which the rate of planet detection is rising rapidly.  I review accomplishments to date and then discuss the observational prospects as well as theoretical challenges of this new era.
