Dawn spacecraft, a million kilometers away
Filed under pretty pictures, pics of spacecraft in space, Dawn, spacecraft, optical telescopes, animation
This blink animation consists of two 14-minute exposures. The faint speck that moves between the two images is the Dawn spacecraft, a million kilometers from Earth (about three times the Earth-Moon distance), and moving very fast. The telescope tracked Dawn during the long exposures, so the stars in the field of view form long and much brighter trails; the spacecraft glinted at only 20th magnitude at the time of the observation.
