The Pillars of Creation are set off in a kaleidoscope of color in the NASA/ESA/CSA 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.
The NASA/ESA/CSA 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. 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.
The James Webb Telescope is the gift that keeps on giving. So far it has found interstellar dust between two galaxies, taken a clearer picture of Neptune, given us new insights into its rings, and much more. It also detected a unique triple start system and gave us better images of Jupiter too. And this is just a partial list of all of its achievements.
Newly formed protostars are the scene-stealers in this Near-Infrared Camera (NIRCam) image. These are the bright red orbs that typically have diffraction spikes and lie outside one of the dusty pillars. When knots with sufficient mass form within the pillars of gas and dust, they begin to collapse under their own gravity, slowly heat up, and eventually form new stars.

What about those wavy lines that look like lava? NASA explains that these are ejections from stars that are still forming within the gas and dust. Young stars periodically shoot out jets that collide with clouds of material, like these thick pillars. This sometimes also results in bow shocks, which can form wavy patterns like a boat does as it moves through water. The crimson glow comes from the energetic hydrogen molecules that result from jets and shocks. This is evident in the second and third pillars from the top – the NIRCam image is practically pulsing with their activity. These young stars are estimated to be only a few hundred thousand years old. B
This scene was first imaged by the NASA/ESA Hubble Space Telescope in 1995, and again in 2014, but many other world-class observatories have also stared deeply at this region, like ESA’s Herschel Telescope. Each advanced instrument offers researchers tantalizing new details about this region, which is practically overflowing with stars.
Webb’s new view of the Pillars of Creation will help researchers revamp their models of star formation by identifying far more precise star populations, 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.
