When iOS 8 was released, I went looking for some new backgrounds for my phone and managed to stumble across this set of images from the Spitzer Space Telescope.

The set is beautiful, but a small device doesn’t really do them justice. So, when OS X Yosemite was released this past week, I went back to the source images to see if I could prise out some larger versions that might really show off the transparency effects of the new OS.

Shown here is a sample of what I was able to pull out. I took the largest possible “standard” monitor resolution for each one, though some are smaller due to the field of view of the originals.

The full set of images can be found here, most of them in 2560 x 1440.

Additionally there are some incredible 5k (5120 x 2880) images suitable for the newest 27″ retina iMacs. You can find them for download separately here.

Note: There are some very large originals 500mb+ in size each that could be used to create more of these, even screen-spanning versions, and likely all 5k. My MBPro balked at editing them in any reasonable amount of time, however. 🙂
