NASA’s Webb Space Telescope reveals the chilling pillars of creation

Webb highlights the velvet-like coating of dust throughout this star-forming region, including the shells around actively forming stars

As seen here, the pillars of creation appear otherworldly in mid-infrared light.[{” attribute=””>NASA’S James Webb Space Telescope has captured an incredible scene that is large and lofty – and appears lit by flickering lanterns. A “ghost” haunts the crag in the lower left, a gargoyle-like shape snarls toward the middle of the frame, and a dark horse’s head charges out of the edge of the second pillar. The creepiest of all? Newly formed stars take on the appearance of protruding, bloodshot eyes. And in the background, dust dances like heavy, ancient curtains being pulled shut. Here, there is no raven to whisper, “Nevermore,” to harken to the classic Edgar Allan Poe poem.

Instead, dust in Webb’s image is like the dawn. It is an essential ingredient for star formation. Though cloaked, these pillars are bursting with activity. Newly forming stars hide within these dark gray chambers, and others, like red rubies, have jumped into view. Over time, Webb’s mid-infrared image will allow researchers to deeply explore the gas and dust in this region, and more precisely model how stars form over millions of years.

Compare NASA’s James Webb Space Telescope’s mid-infrared image of the Pillars of Creation with its near-infrared image in this short video tour. Thousands of stars have formed in this region, but interstellar dust obscures the scene in mid-infrared light, so most stars appear to be missing. A quick dissolve of the near-infrared image shows they’re still there, of course. Although mid-infrared light specializes in detailing where the dust is, and these pillars are filled with dust and gas, many stars in this region don’t have enough dust to show up at these wavelengths. Instead, mid-infrared light reveals which of the young stars still have their dusty “mantles”. These are the crimson orbs towards the pillar fringes. Instead, the blue stars that dot the scene are aging, meaning they’ve already shed most of their layers of gas and dust. How vast is this landscape? This bright red star and its dusty shroud are larger than the size of our entire solar system.

Unsettling Portrait: NASA’s Webb Reveals Dust, Structure at Pillars of Creation

This image does not represent the spreading soot-tinged fingers. Nor is it an ethereal landscape of time-forgotten tombs. These pillars, densely filled with gas and dust, surround stars that are slowly forming over many millennia. NASA’s James Webb Space Telescope captured this strange and extremely dusty view of the Pillars of Creation in mid-infrared light. It reveals a chilling new vision of a familiar landscape.

Why does mid-infrared light create such a somber, eerie mood in the Webb Mid-Infrared Instrument (MIRI) image? Interstellar dust obscures the scene. And while mid-infrared light specializes in detailing where the dust is, stars aren’t bright enough at those wavelengths to show up. Instead, these looming, leaden pillars of gas and dust glow at their edges, only hinting at the activity within.

Thousands and thousands of stars have formed in this region. This becomes explicitly clear when examining Webb’s latest Near infrared camera (NIRCam) image. (see image below). However, according to MIRI, most of the stars appear to be gone. Because? Many newly formed stars are no longer surrounded by enough dust to be detected in mid-infrared light. Instead, MIRI observes young stars that have not yet thrown off their dusty “cloaks”. These are the crimson orbs towards the pillar fringes. Instead, the blue stars that dot the scene are aging. This means they have already shed most of their layers of gas and dust.

Mid-infrared light is particularly suitable for observing gas and dust in intricate detail. This is also unmistakable throughout. Darker shades of gray are areas of denser dust. The red region towards the top, which forms a strange V, like an owl with outstretched wings, is where the dust is diffused and cooler. Note that no background galaxies appear: the interstellar medium in the densest part of the[{” attribute=””>Milky Way’s disk is too swollen with gas and dust to allow their distant light to penetrate.

How vast is this landscape? Trace the topmost pillar, landing on the bright red star jutting out of its lower edge like a broomstick. This star and its dusty shroud are larger than the size of our entire solar system.

This scene was first captured by NASA’s Hubble Space Telescope in 1995 and revisited in 2014, but many other observatories, like NASA’s Spitzer Space Telescope, have also gazed deeply at the Pillars of Creation. Astronomers gain new information with every observation. Through their ongoing research, they build a deeper understanding of this star-forming region. Each wavelength of light and advanced instrument delivers far more precise counts of the gas, dust, and stars, which inform researchers’ models of how stars form. As a result of the new MIRI image, astronomers now have higher resolution data in mid-infrared light than ever before, and will analyze its far more precise dust measurements to create a more complete three-dimensional landscape of this distant region.

The Pillars of Creation is set within the vast Eagle Nebula, which is located around 6,500 light-years away from Earth.

The James Webb Space Telescope is the most powerful space telescope ever constructed and the world’s premier space science observatory. It will solve mysteries in our solar system, look beyond to distant worlds around other stars, and probe the mysterious structures and origins of our universe. Webb is an international program led by NASA with its partners, ESA (European Space Agency) and CSA (Canadian Space Agency).
