The World Science Festival is officially underway in New York City.
For the past three years, the festival has brought together scientists, artists, authors and others for a series of events designed to promote interest and education in the arts and sciences.
The festival began Wednesday, and included an opening gala at Lincoln Center. The event honored physicist Stephen Hawking and featured the premiere of "Icarus at the Edge of Time," a work loosely inspired by the Greek myth and based on Brian Greene's children's book of the same name. Philip Glass composed the score.
The festival runs from June 2 to June 6, and features 40 different events -- ranging from ruminations on whether life exists beyond Earth, to discussions of science and popular culture -- throughout all five boroughs. The festival will end on Sunday, with a free, all-day street fair in Washington Square Park.
