Where do the stars go during the day? They're still there of course but the bright blue daylight sky washes them out. Well, unless you have access to a small telescope. On May 23, 2007, the Moon passed close to Alpha Leonis or Regulus, which is the brightest star (apparent magnitude +1.34) in the constellation of Leo the Lion (lower right of photo).
