The Microcanyon was taken with a microscope from FEI's Nova DualBeam Family, unlike the other two which were taken with microscopes from the Quanta family. The Quanta microscope was also used to take this image of a hydrothermal worm that rocked the internet.
This year's winner, however, was taken at an extremely high magnification, with a width of just 67µm, making it more than what it seems. In reality it's a micro-crack in a piece of steel, taken after multiple bending tests.
This is crazy stuff!It looks like the Grand Canyon or something like that.
