Pillars of Creation (NIRCam Image)

Pillars of Creation (NIRCam Image)

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 almost 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.

About The Image
Color Info These images are a composite of separate exposures acquired by the James Webb Space Telescope using the NIRCam instrument. Several filters were used to sample different infrared wavelength ranges. The color results from assigning different hues (colors) to each monochromatic (grayscale) image associated with an individual filter. In this case, the assigned colors are:    Purple: F090W, Blue: F187N, Cyan: F200W, Yellow: F335M, Orange: F444W, Red: F470N
Compass Image At the bottom left of this vertical image are the thickest regions of brown and rusty red gas and dust. There are many layers of semi-transparent gas and dust overlaying one another. A peak rises about a third of the way from the bottom, and becomes far darker brown with two bright red areas toward the tip. The light brown dust becomes more diaphanous about halfway up the screen. There’s a slight gap in the dust, which allows the blue background to come into view clearly. About 60% of the background in this image is set in shades of blue and littered with tiny yellow and blue stars. The brown pillars continue, taking the shape of a shoulder at the base, with three prominent columns rising out toward the upper right. The top left pillar is the largest and widest. The peaks of the second and third pillars are set off in darker shades of brown and have red outlines. For more details, download the Text Description.
About The Object
Object Name A name or catalog number that astronomers use to identify an astronomical object.
Object Description The type of astronomical object.
R.A. Position Right ascension – analogous to longitude – is one component of an object's position.
Dec. Position Declination – analogous to latitude – is one component of an object's position.
Constellation One of 88 recognized regions of the celestial sphere in which the object appears.
