In 1995, the Hubble Telescope snapped a stunning photo in the Eagle Nebula, 6,500 light years from Earth. The photo revealed three gigantic columns of cold gas, illuminated by the ultraviolet light from nearby young stars. The Pillars of Creation became one of the telescope’s most iconic and popular images.
