Take A Look At This 10 Trillion Pixel Image Of The Night Sky A photograph of the northern sky that weighs in at a whopping petabyte has become a treasure trove of information for astronomers. Space is an impossibly massive zone that countless stars and planets reside in, and if you want to capture even a fraction of the sky then you're going to have to approach that challenge with some equally gigantic ideas. Astronomers across the world gathered for a chance to capture a photo of the northern sky according to SyFy, pooling resources over six years to create a 10 trillion pixel image.
