Nasa's Landsat mission is the world's longest-running satellite imagery program, and this week it celebrates its 40th birthday.
The first Landsat craft, the Earth Resources Technology Satellite, was launched on 23 July 1972, and the most recent was launched in 1999.
The images sent back have a huge range of uses, from mapping uncharted areas to dealing with climate change, urban planning, surveillance and geology.
"Landsat has given us a critical perspective on our planet over the long term and will continue to help us understand the big picture of Earth and its changes from space," said NASA Administrator Charles Bolden. "With this view we are better prepared to take action on the ground and be better stewards of our home."
Nasa collects the most beautiful of these images in its Earth As Art collection, and to mark the 40th anniversary asked its supporters to vote for their favourites.
The top five selections have now been picked out of 14,000 votes, and have been released in full to mark the occasion.
Take a look at the best in the slideshow below.
