People around the world are being asked to smile and wave in the direction of Saturn today as the Cassini probe take a photograph of earth from its orbit around the planet.
The earth may only appear as a single blue pixel at the distance from which Cassini will be taking the image, but Cassini scientist Carolyn Porco says it is a moment to “celebrate life on the Pale Blue Dot”.
“Waving time” for the UK is between 22:27 and 22:42 BST (21:27-21:42 GMT) – the period when the spacecraft’s cameras will be operating – starts at 21:27 GMT and ends at 21:42 GMT (22:27-22:42 BST). See the list below for for the times to wave in other countries around the world:
