Space photography requires a camera—a really big camera. One with 32 CCD sensors that snaps pictures at a mind-bending 268-megapixel resolution. Go ahead, you can call it the OmegaCam.
You may want to take this one home with you, but you can't. It weighs a whopping 1700lbs and produces about 30TBs of data per year. It's also the camera portion of the VLT Survey Telescope (VST), which is the world's largest telescope designed to operate in visible light. It resides in the northern Chile and is part of the European Southern Observatory. [ESO via PetaPixel and PhotoRadar]
