And here I thought it was the proverbial light at the end of the tunnel.
It's not your eyes, AOA. I can juuuuuust barely make it out if I look at the full-sized image at 100%. But it's probably the closest moon (Io), right at the 3 o'clock position. You can see what looks like a bump on the surface of Jupiter, and the glare from the planet almost obscures it.I can make out three of the moons but not the fourth. Probably my monitor and old eyes.
