Pillars of creation eagle

The Pillars of Creation in the Eagle Nebula (M16) are iconic structures of gas and dust where new stars are born, 7,000 light-years from Earth.

About this subject

The Pillars of Creation are part of the Eagle Nebula, also cataloged as M16 or NGC 6611, located in the constellation Serpens, approximately 7,000 light-years away. This region is an active stellar nursery, where molecular clouds collapse to form new stars. The nebula was discovered by Swiss astronomer Jean-Philippe Loys de Chéseaux in 1745-1746, but the pillars gained worldwide fame with the Hubble Space Telescope image in 1995.

Each pillar extends about 4 to 5 light-years in height, composed primarily of molecular hydrogen and interstellar dust. At the top of these formations, denser gas clumps called evaporating gaseous globules (EGGs) harbor protostars in formation. Ultraviolet radiation from young, massive stars located outside the image gradually erodes the pillars, a process known as photoevaporation, which reveals the nascent stars.

The original Hubble image, taken on April 1, 1995, became one of the most reproduced in astronomy history, symbolizing the stellar life cycle. Later observations with the Spitzer Space Telescope (infrared) and the James Webb Space Telescope (JWST) revealed internal structures and stars hidden by dust. In 2022, JWST captured a new version of the Pillars, showing unprecedented detail with its infrared sensitivity.

The pillars are slowly disintegrating over millions of years, but while they exist, they continue to provide valuable insights into star formation. The name "Pillars of Creation" was coined by the Hubble team, referring to their majestic appearance and role in creating new stars. The Eagle Nebula is visible with small telescopes in the northern hemisphere during summer, but the pillars themselves are too faint for amateur observation, requiring long exposures and specialized equipment.

Frequently Asked Questions

What are the Pillars of Creation?

They are structures of interstellar gas and dust in the Eagle Nebula (M16) where stars are being born. They span several light-years and are sculpted by radiation from nearby stars.

Where are the Pillars of Creation located?

They are in the constellation Serpens, about 7,000 light-years from Earth, within the Eagle Nebula (M16), an active stellar nursery.

Why are they called the Pillars of Creation?

The name was coined by the Hubble Space Telescope team in 1995, due to their majestic appearance and key role in forming new stars, symbolizing the celestial creation process.
