Thousands of astronomy fans looked to the heavens and posed for a unique picture on Friday afternoon - a shot of planet Earth from Saturn.
The first photos are are just being transmitted back now - but anyone who participated in the 'Day the Earth Smiled' shouldn't hope to see their face. This was, after all, a 898million-mile photo op.
The photos, some of which have been enhanced by astronomers, show Earth as a tiny dot - only a little bigger than the North Star appears in our sky - illuminating the skies beyond Saturn.
The images were taken by the Cassini spacecraft, which has been orbiting the ringed giant since its arrival in the Saturn system in 2004.
A tiny spot: Planet Earth can been seen as just a miniscule star from this enhanced shot of Saturn taken by the NASA spacecraft Cassini nearly 900million miles away
Magnified: An Argentine physicist blew up the images of the Earth to show our planet and the moon as they might look from a telescope from Saturn
Say cheese! Thousands of people posed for Cassini's pictures - though the gesture was obviously just symbolic
The costumed revelers at San Diego's Comic Con also posed to look up at the heavens
Stargazers in California took a break from their day to gaze up at the spot were Saturn would appear in the daylight sky
Photo bomb: Earth will appear in the image NASA is trying to capture of Saturn
