These towering cosmic columns, nicknamed the “Pillars of Creation,” are dense molecular gas formations within the Eagle Nebula (M16), about 7,000 light-years away. Made visible in this high-resolution Hubble mosaic, each pillar spans several light-years in length and marks zones in which newborn stars are forming and disrupting their dusty nurseries.

Seen here in narrowband filters assigned false colors—hydrogen in green, sulfur in red, and oxygen in blue—the image reveals the physical and chemical composition of the pillars. Within the dark interior regions, dense pockets of gas collapse under gravity, forming protostars. As these stars ignite, they emit intense ultraviolet radiation that ionizes surrounding gas and drives powerful stellar winds. Over time, this radiation erodes the pillars from their tips inward, carving sculpted structures that point back toward the radiation source. This dynamic interplay of formation and erosion encapsulates star birth’s dual nature.

At the edges of the pillars lie Evaporating Gaseous Globules (EGGs)—tiny comet-shaped features that harbor embryonic stars. Only dense enough to resist the radiation pressure, these EGGs may survive long enough for the protostar within to gain mass. If the surrounding material dissipates too quickly, stellar embryo growth can stall.

The Pillars’ dramatic appearance belies a delicate balance between gravity and photoionization pressure. Modeling shows that the pillars likely formed over thousands to tens of thousands of years, as radiation continuously peels away outer layers. Eventually, all that remains will be star clusters and dispersed gas.

This image remains iconic because it captures both creation and destruction in stellar nurseries. It illustrates how newborn stars sculpt their own environment, revealing the interdependence of radiation, ionization, gravity, and gas dynamics. For astronomers, the pillars offer a natural laboratory: by studying their structure, composition, and evolution, researchers probe the earliest stages of star formation and the lifecycle of molecular clouds.
