People from 40 countries and 30 U.S. states shared 14,000 selfies for an other-worldly collage. 

The Wave at Saturn project was organized by NASA's Cassini mission, which turned the camera back on Earth from the ringed planet, a NASA press release reported.

A collage made from the participants' photos is available online. Scientists are also putting together a "colorful mosaic" of Saturn, which should take several more weeks to complete.

"Thanks to all of you, near and far, old and young, who joined the Cassini mission in marking the first time inhabitants of Earth had advance notice that our picture was being taken from interplanetary distances," Linda Spilker, Cassini project scientist at NASA's Jet Propulsion Laboratory, said."While Earth is too small in the images Cassini obtained to distinguish any individual human beings, the mission has put together this collage so that we can celebrate all your waving hands, uplifted paws, smiling faces and artwork."

The images were sent via social media outlets such as: "Twitter, Facebook, Flickr, Instagram, Google+ and email."

Outer space has been getting more interactive in the internet days.

An "asteroid zoo" by Zooniverse allows people to search for dangerous asteroids right from their home computers, a press release reported.

"Planetary Resources values the power of the connected mind; when working together, we can accomplish much more than any of us can do alone," Chris Lewicki, President and Chief Engineer, Planetary Resources, Inc., said. "We're creating this program to harness the public's interest in space and asteroid detection, while providing a very real benefit to our planet."

The Lone Signal Project lets anybody send their own personalized message into the deep reaches of space, reported.

Users can send their own "beam" into space, they also have the option to dedicate a message to someone else.

"It's important that it is feasible for anyone to take part in this experiment because it is so unique. It's never been that case that anyone on the face of the Earth can commune with the cosmos, and we are opening up that portal to the masses," Lone Signal chief marketing officer Ernesto Qualizza said, reported.
