The New Horizons team released one more picture from Tuesday's encounter, one of three high-resolution images from a mosaic that crossed the center of Charon's disk, and it took me a while to figure out what it reminded me of.

Our own Dr. Bruce Betts is once again teaching his Introduction to Planetary Science and Astronomy college course online. Come join him.
3D images generated by the Apollo Lunar Surface Closeup Camera give you an idea of how it would look to crouch on the lunar surface with your spacesuit faceplate to the soil.
Watch as our enormous moon -- a quarter the diameter of the planet -- just winks out as it passes into Earth's long shadow, in an animation captured from more than 100 million kilometers away.

October 2014 brings big sky fun: a total lunar and partial solar eclipse, both visible from North America. The lunar eclipse will also be visible from most areas around the Pacific Ocean. Here is info on how to observe these eclipses.
Despite the fact that it hasn't moved for 6 months, the plucky Yutu rover on the Moon is still alive. Its signal is periodically detected by amateur radio astronomers, most recently on July 19. A story posted today by the Chinese state news agency offers a new hypothesis to explain the failure of the rover's mobility systems.
A few people think that when it comes to the Moon, because we’ve “been there, and done that,” there is nothing new left to discover. But that viewpoint could not be farther from the truth!
The Planetary Society Supports NASA's Asteroid Initiative
But we need to know the cost
The Planetary Society strongly supports NASA's asteroid initiative, including the goal of redirecting an asteroid to the vicinity of the Moon. But an independent cost estimate is needed, and needed soon.

Earth's brilliant colors shine above the drab lunar horizon in this new "Earthrise" photo from the Lunar Reconnaissance Orbiter. An animation that accompanied the image release helped me to write an explainer on how pushframe cameras like Lunar Reconnaissance Orbiter's Wide-Angle Camera works.
LADEE ended its mission as planned with a crash into the lunar surface on April 17. Just days prior, it turned its star tracker camera toward the lunar horizon and captured a striking series of images of the lunar sunrise and zodiacal light.
What can a 45-year-old mission to the Moon tell us about a "meteorite" flying past a skydiver on Earth?
