... More than 200 microlensing events have been detected during the last ~4 years, most of them towards the galactic bulge. Since the line of sight towards the bulge passes through the disk and the bulge itself, the known stars towards the bulge play a dominant role as gravitational lenses. If these stars have planets around them, then the signature of the planets can be seen as sharp, extra peaks on the microlensing light curves. ... Status of some other similar efforts will be briefly discussed. ...
