“This image shows the pillars as seen in visible light, capturing the multi-coloured glow of gas clouds, wispy tendrils of dark cosmic dust, and the rust-coloured elephants’ trunks of the nebula’s famous pillars.“

(Hubble Space Telescope, 2015)

In this image from Hubble Telescope, we see the “Eagle Nebula” – a young cluster of stars in the constellation Serpens with bright blues and greens swirling together in pillars of clouds. It may surprise some to learn that such images were, in fact, originally greyscale-colored and that the colors were added using color filters that illustrate the colors associated with the chemical elements in the nebula.

There is no doubt NASA and ESA/Hubble manipulated these images, but the question arises whether this form of coloring should be mentioned more prominently than is currently done. Scholarly research generally demands transparency, yet one of the largest research facilities does not state clearly that the colors do not reflect the Hubble Telescope image. Uninformed viewers may believe that by looking through a telescope, one sees these amazing and awe-inspiring sights, while the colors are actually rendered after Hubble Telescope took the greyscale image.
