From NASA:
"This Earth Day, April 22, NASA is asking people around the world to share pictures and videos on social media that show there is no place like home - planet Earth.
"NASA's Earth Day #NoPlaceLikeHome project seeks to get the public involved in highlighting the great diversity of the places, landscapes and ecosystems of our home planet. Participants are invited to post photos and videos that answer a simple question: What is your favorite place on Earth?
"Images can be shared using the hashtag #NoPlaceLikeHome on Twitter, Instagram, Vine, Facebook, Google+ and Flickr. Leading up to Earth Day, NASA will participate by posting its own images and videos.
"NASA's mission includes exploring beyond Earth and using the vantage point of space to improve our understanding of the most complex planet we've seen yet. The agency's Earth-observing satellites, airborne research and field campaigns are designed to observe our planet's dynamic systems - oceans, ice sheets, forests and atmosphere - and improve our ability to understand how our planet is changing and could change."
