On October 28th, the Cassini spacecraft flew through the geyser plume of Saturn's moon Enceladus. But Cassini was not the only spacecraft operating in the solar system that day.

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.

Planetary transits of the Sun by Mercury and Venus don't come along very often, and when they do we make a big deal of it because, well, it's really cool!

The European Space Agency will announce two major science missions this November, one of which is likely to be devoted to solar system exploration.

Six months ago, I wrote about the Russian weather satellite Elektro-L, which has more than two years of successful experience in the geostationary orbit. Then I promised that I would be here to share the materials that we collected. I think it's time to deliver on the promise.

Comet PANSTARRS is delighting northern hemisphere viewers right now. But it's also big, bright, and beautiful to the STEREO spacecraft.
