NASA has shared captivating images of the ‘Pillars of Creation’ in the Eagle Nebula, a prominent star-forming region located approximately 7,000 light-years away in the constellation Serpens. These pillars, towering several light-years in length, are composed of cool molecular hydrogen and dust, which are gradually eroding due to photoevaporation caused by the ultraviolet light emitted by nearby hot stars.
The first image, captured in visible light, unveils intricate details of the pillars, with vibrant hues of blue representing oxygen, red indicating sulfur, and green representing both nitrogen and hydrogen. In contrast, the second image, captured in near-infrared light, provides a unique perspective, revealing the semi-opaque, rusty-red coloration of the pillars. The third pillar is partially obscured by a darker brown hue, while the background is adorned with a myriad of stars twinkling in various sizes and hues of yellow and white.
By analyzing these images captured at different wavelengths, scientists can gain a more precise understanding of the star formation processes occurring within and beneath the pillars. The near-infrared image, in particular, allows researchers to penetrate the opaque dust and gas, providing valuable insights into the hidden stellar populations.
