Carnival of Space #22 Online

A Carnival of Space essential, from the 22nd iteration of the weekly roundup, is Universe Today‘s look at color in astrophotography. Is space really the gorgeous place suggested by many images from both terrestrial and space-based telescopes? Sometimes yes, sometimes no. A revealing quote on Hubble imagery from Zolt Levay (Space Telescope Science Institute): “For one thing [color] is somewhat meaningless in the case of most of the images, since we generally couldn’t see these objects anyway because they are so faint, and our eyes react differently to colors of very faint light.” How images passed through various filters are produced is a fascinating topic that brings a needed reality adjustment after viewing some spectacular scenes. The Carnival always offers good material, but Universe Today‘s piece makes for prime late week reading.
