“The Martian” and Ice Age Astronauts

Two nights ago I sat in a theater watching the film “The Martian.” I loved seeing a viable spacecraft making gravitational slingshots around planets while a stranded, potato-growing astronaut claimed himself the first colonist on Mars. What’s there not to love? Meanwhile, in my coat pocket I carried an object from an entirely different age […]

On the Discovery of Liquid Water on Mars

The first memory I know for sure is the smell of rain. I remember a screen door with holes in it big enough to let in a hummingbird, and outside I could see blue bellies of clouds over a dirt road. I can only figure it was somewhere in Arizona where I was born. I’ve always […]

Mocking Tricks

Caveat: I’m possibly having something like a Cassie-Willyard-Hubble-Moment here – in this case, I learn something new, don’t quite understand it but get all excited about it, and it’s, you know, wrong.  Never mind because I’m all excited anyway because science has found a new way of being confident that what you know is right.  […]

Guest Post: Young Astronomer Looks Back

The Hubble Space Telescope was launched aboard the aptly named Space Shuttle Discovery, 25 years ago this month. This past week (past month, past year) there have been gobs of events to mark the occasion: special talks, videos, a re-released IMAX movie, panel discussions, banquets, art exhibits, and a video contest. There was even an […]

There Goes the Sun

During a total eclipse of the sun, the landscape darkens. But you knew that. What you might not know—what I didn’t know, anyway, when I observed a total solar eclipse on August 11, 1999—is that the experience comes with a lot of other sensory overload. I found myself thinking about that total eclipse while reading about the one […]
