See more information here for the night this picture was taken. 
A nebula is an interstellar cloud of dust, hydrogen, helium and ionized gases. Nebulae are often star-forming regions, in where the formations of gas, dust and other materials clump together to form larger masses, which attract further matter, and eventually will become massive enough to form stars. The remaining materials are then believed to form planets, and other planetary system objects. ― source and more information wikipedia
