I think everyone knows by now that the amazing images NASA shows from the Hubble Telescope are actually composites made from dozens, sometimes hundreds of images. In a rare behind-the-scenes, NASA has released a timelapse of someone doing the work in the greatest of all image editors, Photoshop.
Hubble images are made, not born. 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.org, online home of the Hubble Space Telescope, a Hubble-imaged galaxy comes together on the screen at super-fast speed.
