One Trillion Pixel, 802 GB Image by Microsoft

Yes its an One Trillion Pixel image by Microsoft, this picture of the night sky is the largest and the clearest ever. This image is 802 GB in size. Under the Terapixel project, 1791 pairs of complementary red-blue captures were stitched, thanks to image data from telescopes in California and Australia collected under the Digitized Sky Survey during the past 50 years.

The image here is only a lower pixel version of that original picture. If you wish to see the original one, it would have taken you a couple of years to load this page on your normal broadband connection. One terapixels, means 1,000,000,000,000 pixels displaying the sky in all its glory and taking up a whopping 802 GB of disk space.
Microsoft said, "To view every pixel of the image, you'd need a half-million high-definition televisions. If you tried to print it, the document would extend the length of a football field." Even if you take the higher-DPI route of printing, the photo would be the size of a soccer field.

According to Gizmodo, "Developers ran parallel code on 512 computer cores in a Windows High Performance Computing cluster, and were able to process the raw digitized data in about half a day, according to Microsoft. Once the files were decompressed, they had to undergo some changes to correct the vignetting problem. Red and blue plates had to be precisely aligned to make a color image, and then everything had to be stitched together, which took about three more hours."

Terapixel then used an image optimization program to create a seamless, spherical panorama of the sky. That took about four hours, according to Microsoft. The final image is 802 GB.
