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.
Lake Eyre Landsat 5 Acquired 8/5/2006
The scary face in this image is actually inundated patches of shallow Lake Eyre (pronounced "air") in the desert country of northern South Australia. An ephemeral feature of this flat, parched landscape, Lake Eyre is Australia's largest lake when it's full. However in the last 150 years, it has filled completely only three times.
Algerian Abstract Landsat 5 Acquired 4/8/1985
What look like pale yellow paint streaks slashing through a mosaic of mottled colours are ridges of wind-blown sand that make up Erg Iguidi, an area of ever-shifting sand dunes extending from Algeria into Mauritania in northwestern Africa. Erg Iguidi is one of several Saharan ergs, or sand seas, where individual dunes often surpass 500 meters (nearly a third of a mile) in both width and height.
Meandering Mississippi Landsat 7 Acquired 5/28/2003
Small, blocky shapes of towns, fields, and pastures surround the graceful swirls and whorls of the Mississippi River, the largest river system in North America. Countless oxbow lakes and cutoffs accompany the meandering river south of Memphis, Tennessee, on the border between Arkansas and Mississippi.
Yukon Delta Landsat 7 Acquired 9/22/2002
Countless lakes, sloughs, and ponds are scattered throughout this scene of the Yukon Delta in southwest Alaska. One of the largest river deltas in the world, and protected as part of the Yukon Delta National Wildlife Refuge, the river's sinuous waterways seem like blood vessels branching out to enclose an organ.
Van Gogh from Space Landsat 7 Acquired 7/13/2005
In the style of Van Gogh's painting "Starry Night," massive congregations of greenish phytoplankton swirl in the dark water around Gotland, a Swedish island in the Baltic Sea. Population explosions, or blooms, of phytoplankton, like the one shown here, occur when deep currents bring nutrients up to sunlit surface waters, fueling the growth and reproduction of these tiny plants.
