"Earth from Space" features satellite imagery with an environmental twist.
Greenish phytoplankton swirls in the dark water surrounding Sweden's Gotland Island in the Baltic Sea, evoking the look of Vincent van Gogh's famous painting "Starry Night." This masterpiece was acquired by the Landsat 7 satellite in 2005, and ranks as one of the top five images from the 41-year-long Landsat Earth observation program.
Plankton blooms like the one seen here occur when deep currents bring nutrients up to sunlit surface waters, fueling the proliferation of the tiny marine plants. This Swedish sea scene is one of more than 150 satellite vistas offered in "Earth From Space," a coffee-table book assembled by environmentalist photographer Yann Arthus-Bertrand.
Look for more pictures from "Earth From Space" in future installments of our Cosmic Log Space Advent Calendar, a photographic series that runs through Christmas.
