The main photograph is broken up into eight sections on NASA’s Spitzer website, and each section is 67,500 pixels across. As Smithsonian.com noted, a print of the full image would be about 150 feet wide.
So what, exactly, is included in this massive 6-gigabyte photograph? Only about 300 billion stars — many of which are 13.2 billion years old — that occupy a galaxy roughly 100,000 light-years in diameter.
Very cool for the insignificant specks we are.
