The colors in Hubble images aren’t always what we would see if we were able to visit the imaged objects in a spacecraft. These single-color images are then combined to make the final picture. Hubble scientists and image processors create Hubble’s beautiful color images by adding an individual color to each separate black-and-white filtered image. Hubble's filters work the same way, allowing only a specific color of light to pass through. A colored-glass window allows only its particular color of light to pass through – it filters out the other colors of the spectrum. As a result, every image Hubble sends to Earth is in black and white. Once the unwanted light has been filtered out, the remaining light is recorded. Hubble uses special filters that allow only a certain range of colors through.

Its sensitive electronic detectors count each bit of light that hits the camera, but don’t directly record the color of the light.Characterizing Planets Around Other Stars.Measuring the Universe's Expansion Rate.
