Science is awesome. Thanks to the internet age, it's easy to be witness to that fact. For example? This beautiful image of the photomultiplier tubes in the Daya Bay Neutrino Experiment detectors, which mesmerised millions when it started circulating online this week.
However, some of us questioned what we saw, asking how the image could possibly be real. So for your viewing pleasure — and for the sceptics out there — here is a collection of similarly huge and fantastical scientific experiments and machinery.

The Sudbury Neutrino Observatory (SNO), exterior and interior. It is located more than a mile underground in Vale Inco's Creighton Mine in Sudbury, Ontario, Canada.
The Borexino Experiment, located at the Laboratori Nazionali del Gran Sasso near the town of L'Aquila, Italy, measures the solar neutrino flux and its day/night asymmetry.

The late Cockcroft Walton generator of Fermilab. Sadly, it's been decommissioned.
The Z machine, or the Z Pulsed Power Facility, is the largest X-ray generator in the world, designed to test materials in extreme conditions. It is located in Albuquerque, New Mexico, at Sandia National Laboratories. The electromagnetic pulse causes impressive lightning when the machine is discharged.
