Summary

The Pillars of Creation are set off in a kaleidoscope of color in NASA’s James Webb Space Telescope’s near-infrared-light view. The pillars look like arches and spires rising out of a desert landscape, but are filled with semi-transparent gas and dust, and ever changing. This is a region where young stars are forming – or have barely burst from their dusty cocoons as they continue to form.
Newly formed stars are the scene-stealers in this Near-Infrared Camera (NIRCam) image. These are the bright red orbs that sometimes appear with eight diffraction spikes. When knots with sufficient mass form within the pillars, they begin to collapse under their own gravity, slowly heat up, and eventually begin shining brightly.
Along the edges of the pillars are wavy lines that look like lava. These are ejections from stars that are still forming. Young stars periodically shoot out supersonic jets that can interact within clouds of material, like these thick pillars of gas and dust. This sometimes also results in bow shocks, which can form wavy patterns like a boat does as it moves through water. These young stars are estimated to be only a few hundred thousand years old, and will continue to form for millions of years.
Although it may appear that near-infrared light has allowed Webb to “pierce through” the background to reveal great cosmic distances beyond the pillars, the interstellar medium stands in the way, like a drawn curtain.
This is also the reason why there are no distant galaxies in this view. This translucent layer of gas blocks our view of the deeper universe. Plus, dust is lit up by the collective light from the packed “party” of stars that have burst free from the pillars. It’s like standing in a well-lit room looking out a window – the interior light reflects on the pane, obscuring the scene outside and, in turn, illuminating the activity at the party inside.
Webb’s new view of the Pillars of Creation will help researchers revamp models of star formation. By identifying far more precise star populations, along with the quantities of gas and dust in the region, they will begin to build a clearer understanding of how stars form and burst out of these clouds over millions of years.
The Pillars of Creation is a small region within the vast Eagle Nebula, which lies 6,500 light-years away.

Webb’s NIRCam was built by a team at the University of Arizona and Lockheed Martin’s Advanced Technology Center.

The Pillars of Creation are a famous astronomical feature located in the Eagle Nebula, a cloud of interstellar gas and dust in the constellation Serpens. The Pillars of Creation are massive pillars of gas and dust that are thought to be the site of ongoing star formation. The Pillars of Creation were first observed and photographed by the Hubble Space Telescope in 1995, and the image quickly became iconic. The Pillars of Creation are considered a stunning example of the beauty and complexity of the universe, and they continue to be studied by astronomers today. The three-dimensional pillars look like majestic rock formations but are far more permeable. These columns are made up of cool interstellar gas and dust that appear – at times – semi-transparent in near-infrared light. NASA’s James Webb Space Telescope has captured a lush, highly detailed landscape – the iconic Pillars of Creation – where new stars are forming within dense clouds of gas and dust. Webb’s new view of the Pillars of Creation, which were first made famous when imaged by NASA’s Hubble Space Telescope in 1995, will help researchers revamp their models of star formation by identifying far more precise counts of newly formed stars, along with the quantities of gas and dust in the region. Over time, they will begin to build a clearer understanding of how stars form and burst out of these dusty clouds over millions of years.
