The precious data from the cutting-edge space telescope is only digestible thanks to the creative work of the image processing team.
But the human eye can’t see infrared light. That means the Webb data needs to be translated into visible wavelengths, something that’s just as much art as science. The image processors have to choose which aspects of an image to play up or down, depending on what is scientifically most interesting. In one picture, that may mean emphasizing the contrast between two different types of gas in a nebula; in another, it may mean giving more vivid coloration to the energetic regions of star formation.
It took 30 years and $10 billion to get Webb designed, launched, and commissioned. Now that the telescope is operational—and working at a remarkable level of precision—NASA, the European Space Agency, and the Canadian Space Agency want to get everything out of it that they can. The Webb images are inspiring a new generation of space scientists to think beyond the borders of our atmosphere, just as the Hubble Space Telescope did three decades ago.
