In this Hubble Space Telescope image, these eerie, dark pillars are actually columns of gas and dust that are incubators for new stars. They are part of the Eagle Nebula, a nearby star-forming region 6,500 light-years from Earth. Ultraviolet light from nearby, young, massive stars are sculpting and illuminating the giant pillars. The tallest pillar is trillions of miles long.
