Looking back at Earth from beyond helps to give perspective on our place in the cosmos.
January 24 was the 30th anniversary of the Voyager flyby of Uranus. Uranian moons have been on my mind ever since New Horizons sent us close-up images of Charon. On the occasion of the anniversary, Ted Stryk produced latest-and-greatest versions of the Voyager views of these worlds.
I'm back from two weeks' vacation, so it's time to catch up on the status of all our intrepid planetary missions, from Akatsuki to the Voyagers and hitting the Moon, Mars, asteroids, comets, and Saturn in between.
Now that I have a reasonable-resolution global color view of Pluto, I can drop it into one of my trademark scale image montages, to show you how it fits in with the rest of the similar-sized worlds in the solar system: the major moons and the biggest asteroids.
I've been resisting all urges to speculate on what kinds of geological features are present on Ceres, until now. Finally, Dawn has gotten close enough that the pictures it has returned show geology: bright spots, flat-floored craters, and enigmatic grooves.
Last week's Dawn images of Ceres were just slightly less detailed than Hubble's best. This week's are just slightly better.
In honor of the 25th anniversary of the Voyager 2 flyby of Neptune, image magician Björn Jónsson has produced two new global mosaics of the distant ice giant, the highest-resolution ever made.
In 1979, the Voyager 1 probe took a stunning series of images on its final approach to Jupiter. Thirty-five years later, almost to the day, a group of seven Swedish amateur astronomers set out to replicate this odyssey, but with images taken with their own ground-based telescopes.

Cosmos with Cosmos Episode 11: The Persistence of Memory
In which we don't understand intelligence
Cosmos stumbles with an episode that is plodding, scattered, and more than a little preachy. This episode will only persist in my memory as a shadow of what could have been.
