Located approximately 7,000 light-years from Earth and nestled in the constellation Serpens lays the ultimate stellar nursery: the Eagle Nebula. This planetary nebula is home to seven strikingly beautiful pillars, most commonly referred to as the “Pillars of Creation," because it is in these towers that new stars are formed.
