Pillars of Creation

space Maturity 9-11 Next article →

The Pillars of Creation are massive structures of interstellar gas and dust. They are located within the Eagle Nebula in the Serpens constellation. These structures are vital to our understanding of how stars are born. They act as cosmic nurseries where new stars emerge from dense clouds.

Scientists often refer to these shapes as elephant trunks. This name describes their long, finger-like appearance in space.

The pillars are composed of cool molecular hydrogen and dust. A process called photoevaporation is constantly shaping these columns. This happens when ultraviolet light from nearby hot stars hits the gas. The intense light erodes the material, wearing the pillars away over time. At the tops of these clouds, you can see protrusions larger than our entire Solar System.

These shapes are created by the shadows of small, dense pockets of gas.

These dense pockets are known as evaporating gaseous globules, or EGGs. EGGs act as incubators for new stars. The thick gas in an EGG shields the material behind it from intense ultraviolet flux. This protection allows gravity to pull the gas together into a star. Once a star is formed, it emerges from its EGG. The star's growth eventually causes the EGG to evaporate completely.

Humans have been studying these structures for a long time. John Charles Duncan first discovered these elephant trunks in 1920. He used a 60-inch telescope at the Mount Wilson Observatory. In 1995, the Hubble Space Telescope captured a legendary photograph of the region. Astronomers Jeff Hester and Paul Scowen were responsible for this famous image. The name "Pillars of Creation" was chosen by NASA scientists. They used a phrase from an 1857 sermon by Charles Spurgeon.

Many different telescopes have looked at this region to gather data. The Chandra X-ray Observatory observed the area in 2001. It found X-ray sources coming from young stars in the vicinity. The Herschel Space Observatory rephotographed the area in 2011 using far-infrared wavelengths. This allowed scientists to see inside the pillars to study creative and destructive forces. The James Webb Space Telescope provided new views in 2022. It used a tool called NIRCam to see red spots near the pillar edges.

There is a scientific debate about the future of these pillars. Some data from the Spitzer Space Telescope suggests a possible supernova occurred nearby. A supernova is a massive stellar explosion that creates a shock wave. This shock wave might have destroyed the pillars 6,000 years ago. Because the pillars are 7,000 light-years away, we see them as they were in the past. If this theory is correct, we will see the destruction from Earth in about 1,000 years. However, other astronomers argue that winds from massive stars are causing the erosion instead.

Understanding the Pillars of Creation helps us learn about the life cycles of stars. The leftmost pillar alone is about four light-years in length. The Hubble image was made by combining 32 different images from four sensors. These images used colors to represent different elements. Green represents hydrogen, red shows singly ionized sulfur, and blue shows double-ionized oxygen. By studying these colors and structures, astronomers can map the chemistry of our universe. This research connects the study of individual stars to the larger evolution of galaxies.
