The distinctive blue bubble appearing to encircle WR 31a is a Wolf–Rayet nebula — an interstellar cloud of dust, hydrogen, helium and other gases. Created when speedy stellar winds interact with the outer layers of hydrogen ejected by Wolf–Rayet stars, these nebulae are frequently ring-shaped or spherical. via NASA http://ift.tt/1oEvGez

This image, acquired by the Operational Land Imager (OLI) on Landsat 8, shows the glaciers of Sierra de Sangra on Jan. 14, 2015. Snow and ice are blue in these false-color images, which use different wavelengths to better differentiate areas of ice, rock, and vegetation. via NASA http://ift.tt/1T4g2qg
