The Bubble Nebula (NGC 7635) phone screen wallpaper (by DM)
A snap of powerful stellar winds of the central star SAO 20575 (on the 10th hour within the bubble) pushing and expanding surrounding interstellar gas. I've tried to capture and retain as many intriguing details. The colours are an approximation of the so-called Hubble palette in which yellows, oranges, and reds represent ionized hydrogen and greens and blues ionized oxygen.
You'll get two full resolution images of the Bubble Nebula one for the phone and the second one for smart-watch. Please bear in mind that the image is heavily cropped from the original so we're really zoomed in to focus on the funny part. Sadly, this comes with lower resolution given the size of the object and my current equipment. Please do not redistribute without my consent.
