Three Lobes in the Trifid Nebula

The Trifid Nebula, composed of an emission and a dark nebula, appears to possess three lobes owing to the thick dust lanes crossing its bright core (thus inspiring the name of the nebula). 

Radiation pressure from young stars has blown away dust and hydrogen, creating the central cavity.
