The "Mystic Mountain" image released for the Hubble's 20th anniversary showcases a three-light-year tall pillar of gas and dust stretching out of the Carina nebula. Mostly made of cool hydrogen, the structure is created by stars releasing jets of gas, which is worn away by radiation from other nearby stars, giving it its eroded shape.
