The Eagle Nebula Through Hubble’s Lens
The Eagle Nebula is one of the most recognizable star-forming regions in the night sky. Made famous by the Hubble Space Telescope’s dramatic images of towering clouds of gas and dust, it offers a striking view of how stars are born—and how young stars can reshape the environment around them.
Where Is the Eagle Nebula?
Also known as Messier 16, or M16, the Eagle Nebula lies in the constellation Serpens, roughly 6,500 light-years from Earth. It is a vast region of glowing gas and dark dust associated with the young star cluster NGC 6611. The cluster’s hot, massive stars illuminate the surrounding nebula and power much of its visible glow.
The Pillars of Creation
The Eagle Nebula’s best-known feature is the “Pillars of Creation,” a set of enormous columns of cool gas and dust. They appear to reach toward a bright cluster of stars, with dense, shadowy material forming their outlines. The tallest pillar stretches several light-years across—large enough to contain many stars and planetary systems.
These pillars are shaped by the intense ultraviolet radiation and powerful stellar winds from nearby young stars. The radiation heats and erodes the clouds’ outer layers, while denser pockets of material resist that erosion for longer. This process sculpts the gas into ridges, knots, and towering columns.
Hubble’s Changing Views
Hubble’s 1995 image of the Pillars of Creation became one of the telescope’s most celebrated photographs. It showed the structures in visible light, revealing their textured edges and the bright glow of the surrounding gas. In 2014, Hubble observed the region again, producing sharper visible-light views and an infrared image that could peer through some of the dust.
Infrared light passes through dust more readily than visible light, allowing astronomers to see stars hidden behind or within parts of the clouds. Comparing images taken in different wavelengths helps researchers study both the nebula’s structure and the stars developing inside it.
A Stellar Nursery in Motion
The Eagle Nebula is not a still cosmic sculpture. Its gas and dust are continually affected by radiation, winds, gravity, and the formation of new stars. Dense clumps within the clouds may collapse under gravity to form stars, while nearby stellar activity can compress some regions and disperse others.
Because the nebula is thousands of light-years away, its light has taken thousands of years to reach Earth. Hubble’s images therefore show the region as it appeared in the distant past, giving astronomers a snapshot of a stage in its ongoing evolution.
Why the Eagle Nebula Matters
The Eagle Nebula offers a natural laboratory for studying how stars form and interact with their surroundings. Its famous pillars make those processes visible on a grand scale: new stars emerge within dense clouds even as other young stars erode the material around them. Hubble’s observations have made the nebula an enduring symbol of cosmic creation—and a reminder that the universe is constantly changing.

Look for the Pillars of Creation in Hubble’s famous Eagle Nebula images.
Look for the Pillars of Creation in Hubble’s famous images of the Eagle Nebula: towering columns of gas and dust shaped by the light and stellar winds of nearby young stars. These dramatic structures are a celebrated example of a star-forming region, where new stars can take shape within dense clouds.
The Eagle Nebula is also known as Messier 16, or M16.
The Eagle Nebula is also known as Messier 16, or M16—a name astronomers use to identify this famous star-forming region in the constellation Serpens. It is home to the young star cluster NGC 6611 and the iconic Pillars of Creation, captured in some of the Hubble Space Telescope’s best-known images.
It lies about 6,500 light-years from Earth.
The Eagle Nebula, made famous by Hubble’s striking images of the Pillars of Creation, lies about 6,500 light-years from Earth in the constellation Serpens. That distance means its light has traveled for roughly 6,500 years before reaching us, so Hubble reveals the nebula as it appeared long ago. Its immense clouds of gas and dust are a stellar nursery, where new stars are forming.
The nebula is a region where new stars are forming.
The Eagle Nebula is a stellar nursery—a vast region of gas and dust where new stars are forming. As dense pockets of material collapse under gravity, they can grow hot and compact enough to ignite as stars. Hubble’s observations reveal the glowing clouds and dark, towering structures where this ongoing process unfolds.
Hubble’s infrared images reveal stars hidden by dust.
Hubble’s infrared images of the Eagle Nebula reveal stars that are hidden from view in visible light. Infrared light can pass through much of the cosmic dust, allowing astronomers to glimpse objects within and behind the nebula’s dense clouds. These observations help researchers study the region’s young stars and learn more about how stars form inside stellar nurseries.
The pillars are made of cool gas and dust.
The Eagle Nebula’s famous Pillars of Creation are made of cool gas and dust, including dense clouds of material that block visible light. These towering structures are shaped by radiation and stellar winds from nearby young stars, while denser pockets can resist erosion and may collapse to form new stars. Hubble’s observations reveal the pillars’ intricate outlines and help astronomers study the raw material of star formation.
Compare images taken years apart to see changes in the nebula.
Compare Hubble images of the Eagle Nebula taken years apart to spot subtle changes in its clouds of gas and dust. The nebula evolves slowly, so its towering pillars may look almost unchanged at first glance, but careful comparisons can reveal shifts in their edges as radiation and stellar winds gradually reshape them. Looking at images from different dates—and, when possible, different wavelengths—offers a fascinating glimpse of this star-forming region in motion.
