DYN?

Did you know that data from Hubble and Webb telescopes starts out in black & white before being translated into color?

Image developers on the Webb team are tasked with turning the telescope’s infrared image data into some of the most vivid views of the cosmos we’ve ever had. They assign various infrared wavelengths to colors on the visible spectrum, the familiar reds, blues, yellows, etc. But while the processed images from the Webb team aren’t literally what the telescope saw, they’re hardly inaccurate.

“Something I’ve been trying to change people’s minds about is to stop getting hung up on the idea of ‘is this what this would look like if I could fly out there in a spaceship and look at it?’” said Joe DePasquale, a senior data image developer at the Space Telescope Science Institute, in a phone call with Gizmodo. “You don’t ask a biologist if you can somehow shrink down to the size of a cell and look at the coronavirus.”

Astronomy is often done outside the visible spectrum, because many of the most interesting objects in space are shining brightly in ultraviolet, x-rays, and even radio waves (which category light falls into depends on the photon’s wavelength). The Webb Telescope is designed to see infrared light, whose wavelengths are longer than red visible light but shorter than microwaves.

Webb’s raw images are so laden with data that they need to be scaled down before they can be translated into visible light. The images also need to be cleaned of artifacts like cosmic rays and reflections from bright stars that hit the telescope’s detectors. If you look at a Webb image before processing work is done, it’ll look like a black rectangle peppered with some white dots.

“I think there’s some connotations that go along with ‘colorizing’ or ‘false color’ that imply there’s some process going on where we’re arbitrarily choosing colors to create a color image,” DePasquale said. “Representative color is the most preferred term for the kind of work that we do, because I think it encompasses the work that we do of translating light to create a true color image, but in a wavelength range that our eyes are not sensitive to.”
