I was giving an astronomy talk at a Worldcon a few years back and was showing some pictures of some spiral galaxies like this Hubble image of M81: Someone in the audience asked if the spiral shape of hurricanes and galaxies were for the same reason. Here’s a picture of Hurricane Floyd from NASA (who […]

I like stories of all types, not just hard science fiction. I can get excited about a good fantasy, or a good story of any kind. What I can’t stand, however, is the pretending. Crap pretending to be science, making it harder to find the real thing, and making it harder for the public to […]

That’s the topic for my class this week, and I just wanted to share a brief introduction with some links to some interesting videos and history regarding nanotech. Let’s start with NASA Kid’s introduction to nanotechnology. Then there’s a nice, more adult introduction with a summary of current nano state of the art. Historically, the […]

I generally only censor spam or super obnoxious posts from my blog, and luckily haven’t had any in the second category (knock on plastic). I’m in turns bemused and annoyed with comments on some entries, like this one, about the antiscience propoganda piece that is Expelled. I know I’m going to be preaching to the […]

Grrrr!!! No one better tell me about how science reporting is good and I’m being unfair. I dare you. I double dog dare you. My research specialty is quasars. I love quasars. I’m a world expert, and I know more than anyone you know about them, and also what we don’t yet know about them. […]

A comment on my Standing on the Ledge with Jumper post got me thinking about this issue today. I realized that to a great degree my disagreement with others concerns the definition of teleportation, and how I think that the standard has slipped for PR purposes. I think at one extreme every can agree on […]

It’s one of the proposal seasons in astronomy this month. There have been deadlines for applications to use the Hubble Space Telescope, the Chandra X-ray Observatory, and a dozen other ground-based telescopes (e.g., NASA’s IRTF, NOAO’s telescopes at Kitt Peak and Cerro Tololo, etc.). I also just got my CD filled with Hubble Space Telescope […]

Seth Shostak over at space.com has a nice article today mostly about why aliens won’t visit the Earth. I agree with the vast majority of his assessments, and the one reason he proposes that they would. As he points out, most “aliens coming to Earth” stories (at least on TV and in the movies) are […]

Last summer at the Launch Pad workshop, I brougt in my main reference bookshelf for writing space-based hard science fiction. This list is by no means complete (I have books stashed everywhere and loaned out and whatever…who knows where they all end up?) . Here are the results: Bennett, Jeffrey O., and G. Seth Shostak. […]

As a professional astronomer with a faculty job as a professor at the University of Wyoming, I find it very common that people outside of academia don’t really understand what it is I “do.” A lot of misconceptions floating around there, so let me knock some down first before building something in their place. First […]

Why do people read science fiction, and why do people write it? And in a related question, why do some look down on it or feel ashamed to admit to loving it? The answers I feel lie in what science fiction does that other forms of fiction don’t do as well. Here’s what I think […]

“A dark-matter world holds the key to a weapon from the heart of a sun.” That’s the tagline on the cover. My new hard science fiction novel, Spider Star, was published by Tor this week. I’m pretty happy to finally have the book out, the current expression of my attempts to make my career in […]
