Does anyone know why it looks like Pluto has an atmosphere in this picture?
Hey, I've had this as my desktop background for almost a decade now! Easily my favorite picture of anything "space".
As for your question, it looks like Pluto has an atmosphere in the picture because, well, it does. Although it's very thin, Pluto's atmosphere is primarily nitrogen, so if you stood on the surface during daytime the sky would appear a very familiar blue color.
Here's another shot taken by New Horizons where you can see it much more clearly: https://upload.wikimedia.org/wikipedia/commons/0/02/Blue_hazes_over_backlit_Pluto.jpg
Short answer? Because it does. It doesn't take much to be visible compared to space.
I don’t think any planet1 has surprised us more than Pluto.
1 I know. If anyone gets pedantic, they’re reclassified as a dwarf clown.
Oh wow that's really cool! I didn't know.
It's about one millionth of the pressure of earth's atmosphere at sea level.

Hey, fuck you this only happened ... checks watch ... 9 years ago? God Damn, we are getting old.
Hey, if you wanna feel really old, look up how long it's been since Pluto was demoted from being a planet.
spoiler alert: its been 18 freaking years
That's a friggin planet....
Always "Pluto, Pluto, Pluto". Why does no one ever remember Ceres, Eris, Haumea, and Makemake? They're each as much of a planet as Pluto is. Dwarf planets, but planets nonetheless.
It's smaller than the moon, and six other moons
I use this photo as my computer background, it looks so good with a multiple monitor setup or extended display. Sadly I have only my laptop, I do miss having an extra monitor.

Probably reflection of light from the other side if I had to guess.
