This GIF animation shows Pluto on two separate nights. See if you can find it.

At first I concentrated on the middle of the view, but then remembered that if you haven't discovered a planet yet, it could be anywhere 😊

That's still how we find stuff in the outer solar system! Hasn't changed! (Luckily we use software to do the blinking for us, but often still have to check some of it)

Yep. Found it. Helps if you blot out the large blinking artifacts.

(mid left side)

(I don't know, but I assume they are replica plates in the museum. At least I hope they are.)

PS, once you see it, it's impossible to not see.
