Voyager 2's engineers have confirmed that the problem with the spacecraft was indeed the result of a single flipped bit in its software, as they predicted.
On Sunday comes the twentieth anniversary of an iconic image from the Voyager mission: the "Pale Blue Dot" photo of Earth caught in a sunbeam, which was captured by Voyager 1 as part of a Solar System Family Portrait.

Did you think I was going to skip Uranus? How could I?

Here's yet another of the moons of Uranus for you: Ariel, a near-twin in diameter to Umbriel, but apparently with more interesting geology.

Miranda is the one moon of Uranus for which we have very good images from Voyager 2, and that was a stroke of luck, because low-resolution shots of all of Uranus' moons would have told us that it was, geologically speaking, the most dramatic of the five biggest ones.

Here's Neptune, but not quite like you've ever seen it before.

Proteus is a weird name for this world. It's the second-largest moon of Neptune, and so it's named (as are all of Neptune's moons) for deities associated with the sea.
