thespacegoat: Hubble Images are Produced, Not Taken Images...











The individual raw black and white Hubble images are opened and scaled.





Images are aligned in a graphics editing program.





The camera that took this image is made of two light detectorsm separated by a gap. The gaps are filled with data from another camera.





Each image is assigned a color. Combined, they create a full color image.





Cosmetic defects, including bad pixels, cosmic rays and the detector gap, are cleaned.





The color composite is rotated and cropped.

Hubble Images are Produced, Not Taken



Images must be woven together from the incoming data from the cameras, cleaned up and given colors that bring out features that eyes would otherwise miss. In this video from HubbleSite, a Hubble-imaged galaxy comes together on the screen.
