Juno Looks Back, Photographs Earth-Moon System

astroengine writes "Looking back as it zooms through interplanetary space, less than a month into its 445-million mile, five-year journey to the gas giant Jupiter, NASA's spacecraft Juno captured a portrait of the Earth and moon. Juno was 6 million miles away at the time. 'This is a remarkable sight people get to see all too rarely,' said Scott Bolton, Juno principal investigator from the Southwest Research Institute in San Antonio. 'This view of our planet shows how Earth looks from the outside, illustrating a special perspective of our role and place in the universe. We see a humbling yet beautiful view of ourselves.'"

    Give me a break. Obviously, they used Photoshop for two purposes: to convert/resize the image for the web, and to clean up noise artifacts. I have no idea what kind of imaging sensor is on this spacecraft, but I have no doubt its images do contain noise. That isn't real. And that, therefore, can be taken out in post-processing without altering the data of interest.

    And for the people whining that they should just slap any old digital camera on there, I have two words: radiation hardening.
