New matte finished 8" x 10" photo of Star Forming Gas Pillars Eagle Nebula from NASA Hubble Telescope - These columns that resemble stalagmites protruding from the floor of a cavern columns are in fact cool interstellar hydrogen gas and dust that act as incubators for new stars. Inside them and on their surface astronomers have found knots or globules of denser gas. These are called EGGs (acronym for "Evaporating Gaseous Globules"). Inside at least some of the EGGs stars being formed.
