[English] Aurora Slathers Up the Sky 

Like salsa verde on your favorite burrito, a green auroraslathers up the sky in this 2017 June 25 snapshot from theInternational Space Station.About 400 kilometers (250 miles) above Earth,the orbiting station is itself within the upper realm of the auroral displays.Aurorae have the signaturecolors of excited molecules and atoms at the low densitiesfound at extreme altitudes.Emission from atomic oxygen dominates this view. The tantalizing glow is green at lower altitudes, but rarer reddishbands extend above the space station's horizon. The orbital scene was captured while passing over a pointsouth and east of Australia, withstars above the horizon at the right belonging tothe constellation Canis Major ,Orion's big dog. Sirius ,alpha star of Canis Major, is the brightest star nearthe Earth's limb.
