On July 19, the Cassini spacecraft looked back toward Earth, 898 million miles away, and snapped a photo of us — one of many that went into a remarkable mosaic of the Saturn system assembled by mission scientists.

In that composite image, Earth was a pixel-sized pale blue dot.

On that same day people from more than 40 countries and 30 U.S. states snapped pictures of themselves as they waved back at Cassini and posted them to Twitter, Facebook, Flickr, Instagram, etc. Now, using these images, the Cassini mission has assembled a brand new mosaic — the one above.

Pretty cool, eh? But wait. Now you really have to go to this link and then click on the image there. Trust me… But please come back here when you’re done.

Even more cool, right? Positively spectacular, I would say.

Now, spread it around so other Earthlings can enjoy it.

    A really unfortunate amount of doubles, but a lovely idea.

    I must say… I’m NOT impressed…
    But everyone can do what he likes. As long it does not interfere with the live of others!
