In the Arctic summer, there are days when the Sun never sets. This period of extended sunlight offers the chance to observe long expanses of Earth’s northern latitudes from space. On June 21, 2014—the summer solstice—the Operational Land Imager (OLI) on Landsat 8 acquired 52 individual scenes that were subsequently stitched together into one long swath.

And since February 11 marked the two-year anniversary of the launch of NASA’s Landsat 8 satellite. A Earth observation project that began in the early 1970s already. And to celebrate the occasion, NASA released a vast composite image that stretches unbroken from Sweden to British Columbia.
