On January 5 2015, NASA released a partial image of the Andromeda galaxy, which is the closest galaxy to our own Milkyway. Using the NASA/ESA Hubble Telescope to compile the final copy, in total it took 411 images and stacked them together to create the largest image ever taken.
It’s over 1.5 billion pixels and requires 4.3GB of disk space.
