Double Helix

From i09:

Scientists snap a picture of DNA’s double helix for the very first time

George Dvorsky

Though they've never actually seen it with their own eyes, scientists know that DNA's structure is composed of a spiraling corkscrew. They know this thanks to molecular theory and and an old-time technique called X-ray crystallography, where patterns of dots are converted into an overarching image using mathematics. But now, for the first time ever, scientists have actually snapped a real image of DNA using an electron microscope — spiraling corkscrew and all.

See it here.
