“It’s not too hard to see how it got its name, is it? This picture is actually a combination of two separate space telescope images: Hubble and Spitzer, combined by the wonderful astrophotograper André van der Hoeven. The full-res version is 4000 x 2700 pixels, and nothing short of magnificent. The Hubble shot was taken in 2005, and has a total exposure time of an astonishing nine hours. It was taken in visible light, the kind we see, using filters that accentuate starlight and the gas clouds dotting the spiral arms.” — Phil Plait, Slate
