What does a picture of "Everything" look like? I don't know either, but this is a picture of everything in our Galaxy! This is Axel Mellinger's 648 Megapixel Picture of the our home Galaxy
Piecing together 3000 individual photographs, a physicist has made a new high-resolution panoramic image of the full night sky, with the Milky Way galaxy as its centerpiece. Axel Mellinger, a professor at Central Michigan University, describes the process of making the panorama in the forthcoming issue of Publications of the Astronomical Society of the Pacific. An interactive version of the picture can viewed on Mellinger's website.
"This panorama image shows stars 1000 times fainter than the human eye can see, as well as hundreds of galaxies, star clusters and nebulae," Mellinger said.
Go ahead and click on the picture above and you can dive into human scaled version of the picture. You'll have to email Axel himself for a larger version but I bet you won't even be able to handle the small version.
