Emily Lakdawalla • January 30, 2013

Hey planetary scientists! Many of you know that the Lunar and Planetary Science Conference (LPSC) is a great meeting in a venue that is perfect except for one thing: Internet access is positively lousy.

"Sand" means something different to me than it does to you, probably

Emily Lakdawalla • January 24, 2013

I had one of those "A-ha" moments last week where I suddenly realized that I had run afoul of a common problem in science communication: when the words I'm using mean something different to me than they do to almost everyone I'm talking to. The confusing word of the week: "sand."

Voyager 1 revisited: Io and Europa transiting Jupiter

Björn Jónsson • January 22, 2013

Satellite transits are especially beautiful when the resolution is high enough for some details to be visible on the satellites so I decided to check this. And I was remarkably lucky.

Stars, and stars, and stars: pretty pictures from the European Southern Observatory

Emily Lakdawalla • January 21, 2013

My solar system chauvinism is well-established, but I am as much a sucker for beautiful astrophotos as the rest of you. Once in a while I get a media advisory from the European Southern Observatory about a new pretty picture posted on their website, and then I inevitably lose an hour following links to one stunner after another.
