The International Year of Light continues with a beautiful gallery celebrating all aspects of light: multispectral astronomical, technological innovations, bioluminescence, eclipses, and even noctilucent clouds. I'll say this for it: this is the most visually interesting and diverse "Year of..." celebration!
Astronomy relies on seeing in many different wavelengths beyond the mere optical visible to our puny human eyes. See for yourself in interactive images of iconic astronomical objects that allow you to seamlessly slip between seeing through different spectral bands.
That's how the good people at NASA's Astronomy Photo of the Day describe this dust pillar, at any rate, and I know better than to argue with a bunch of astronomers armed with a flair for figurative language. And this gorgeous gas is just one small part of the generally just ridiculously impressive Eagle Nebula.
