twice a year, our omnipotent star, the good ol’ setting sun aligns with the east/west streets of new york city’s grid.  the origin of the word manhattanhenge, popularly dispersed by the enigmatic astrophysicist neil degrasse tyson, comes from stonehenge (their silhouettes and reactions are parallel).  this event occurs annually during the end of may and july 12th and 13th.  in 2013, it occured in half-sun form on may 28th and full sun form on may 29th around 8:15PM respectively.  if you missed this beautiful cosmological event, you will have another chance to witness it in july (the 12th and 13th) around 8:20PM. how appropriate for science week…  by hk
