Stars fade and dust structure shines in longer wavelengths.
Thousands more young stars shine through the nebula's warm, glowing dust.
Forming stars nestle inside dense cocoons of gas and dust, which block their visible light from reaching the telescope.
Most of the stars emitting high-energy X-ray light in the nebula are outside the pillars.
Radiation from hot young stars shapes the pillars via erosion, while also sweeping up gas for gravity to compact into new stars.
A Story Of Star Formation: Eagle Nebula
Stars form from the remains of previous generations of stars.
Stars are formed as part of an amazing recycling process, in which gravity shapes new stars from the gas and dust expelled by old stars. Once formed, massive young stars regulate the formation of lower-mass stars with their powerful winds, blowing gas and dust out of some areas while compressing it in others. As stars form, they are hidden inside their “parent” cocoons of dust that visible light cannot penetrate, but they emit infrared light that passes through the dust clouds and can be detected by infrared telescopes.
The Eagle Nebula offers views of a stellar nursery in multiple wavelengths, allowing us to see both the dense cocoons of dust and the stars forming within. The nebula is home to three thick columns of dust and gas where stars are forming, known as the Pillars of Creation. Even at 5 light-years tall, the pillars have been eroded by stellar winds from young, hot stars, and are nearing the end of their star production phase. Most of the nebula’s stars surround them, bathing them in glowing radiation that continues to chip away at their shape.

Did you know:
We are seeing the Eagle Nebula as it was 6,500 years ago—the time it has taken for its light to reach us. The shape of the pillars has likely changed, but that light has not yet reached us.
