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.
What can a 45-year-old mission to the Moon tell us about a "meteorite" flying past a skydiver on Earth?

This video of class 4 of Bruce Betts' Introduction to Planetary Science and Astronomy class discusses eclipses, Mercury, Venus, and a comparison of the atmospheres of Venus, Earth, and Mars.
A few days ago, Curiosity looked westward after sunset and photographed Earth setting toward the mountainous rim of Gale crater.
Our own Dr. Bruce Betts is once again teaching his Introduction to Planetary Science and Astronomy college course online. Come join him.
Cosmos with Cosmos Episode 12: Encyclopedia Galactica
In which we ponder the existence of others
Cosmos returns in fine form in its penultimate episode. Sagan explores the historical and scientific precedents for the search for extraterrestrial life (SETI) and our human desires to not be alone in the universe.
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.

A higher-resolution version of the Chang'e 3 lander's panoramic view of the lunar surface has appeared on the Web, and artist Don Davis has cleaned it of artifacts to make a beautiful, seamless view. In other news, the mission has been reorganized to accommodate a possibly year-long adventure on the lunar surface.
A pile of Chang'e 3 photos has been released to the Web, and they are much, much better than what I've seen before. They include, for the first time, photos of Earth from the lander.
If there's one thing I've learned after decades of studying the first human voyages to another world, it's that there is always more to discover about Apollo. Case in point: The Apollo 8 Earthrise photo that became one of the iconic images of the 20th century.
Juno's Earth flyby represented the first opportunity for many of the science instruments to be used on a planetary target. There were terrific photos of Earth and the Moon, plus a cool project to see if Juno could detect intelligent life on Earth.

On Sunday, the shadow of the Moon passed across Africa and the Atlantic Ocean. This was the last solar eclipse of the year. The Elektro-L satellite was able to observe the eclipse, and we can see the darkness of the lunar shadow covering Africa.
Juno is in Safe Mode again, but still okay
All Earth flyby data on the ground, including JunoCam images
After entering safe mode last week during its Earth flyby, Juno returned to normal operations and downlinked all engineering and science instrument data. It entered safe mode again on Sunday night, but it is expected to re-resume normal operations late next week.
