The Science Questions That Get Asked

Dumb Questions? NO.

I’ve been following the latest kerfuffle over a CNN anchor asking Bill Nye if a near-Earth asteroid swinging close to Earth had anything to do with global warming.  In watching the video of the question, it’s pretty clear to me that the anchor doesn’t really think that climate change and the asteroid have anything to do with each other. She’s trying to make a transition from one story to the next in a crowded broadcast. But, it was a pretty clumsy segue. Nye’s response was a nice educational linkage between words that astronomers use (like meteors and meteorology, and so on).  I thought he handled it pretty well.

A lot of commentators online have really come down on the anchor for asking what seemed like a dumb question. You know what? There’s no such thing as a dumb question.  There are ill-thought-out questions. There are uninformed questions, and loaded ones and sarcastic ones, but they’re not dumb. This question led to a teachable moment in science for the anchor and presumably for the audience members watching the show. So, it’s all good. Maybe next time the anchor will think twice before asking once. And, maybe somebody in the audience learned something about how scientists should answer questions (even loaded, awkward ones).

There are a lot of really misguided things that people say, particularly when it comes to science.  And, they deserve to get called out on whatever misunderstanding they have that led to the questions. They also deserve rational answers from scientists. I am not for one minute defending the creationist claims about biology or evolution. Those are indefensible because they come from a position of wilful ignorance (and sometimes wilful lying) by those who preach them. Nor am I defending the ideas espoused by the oil and gas companies that are paying scientists to denounce human involvement in global warming and pollution.  Those come from people who have a stake in maintaining the status quo at the expense of the planet and have little to do with the actual science they are deriding.

I am saying, however, that learning involves asking questions. And, that’s why there’s no such thing as a dumb question. Good, honest attempts to find out about our planet,  our life forms, the scientific discoveries that inform us about the cosmos are never dumb.  And, for those of us who bring science to the public, there’s always a teachable moment ? even when a TV anchor asks an awkward question.  I like how Bill Nye handled it. We should all be so quick to use our knowledge to teach.

 

 

 

Stargazing in February

It CAN Be Done!

The first month of the year is behind us now, leaving 11 more months of sky sights to check out. February for many northern hemisphere observers is still the winter season, so of course you have to dress warmly unless you live in relative sunny climes. For southern hemisphere viewers it’s late summer, so the dress code’s a little different. No matter what you wear, though, there ARE some great sky sights to check out.  I outline a few of them in my monthly video called Our Night Sky, produced for Astrocast.TV. You watch it here.

I always come back to Orion for my sky gazing this time of year. It’s just a gorgeous star pattern.  What I like most about Orion: it provides a lot of interesting stuff to look at. There’s Betelgeuse, for example. It’s a red supergiant star in his shoulder, and it’s likely to pop off as a supernova anytime (well, “anytime” is relative — it could be in the next million years).

Notice the three stars across Orion’s middle. Just beneath them lies a spectacular star birth region called the Orion Nebula. It’s about 1,500 light-years away from us and it just blazes with hot young stars, set among clouds of gas and dust that are still forming stars.

I’ve been stargazing since I was a kid. I didn’t always know what I was looking at, but over time (and using star charts and taking a few astronomy classes and teaching in the planetarium) I got to know the sky pretty well. You don’t have to do all that to explore the sky. You can start very simply: take it one constellation at a time.  Look at it with your naked eye, then scan it with binoculars or a small telescope.  Chances are, you’ll find something cool and interesting to check out each time you look.

People often ask me what star charts they should get. I always recommend they check out Sky&Telescope.com or Astronomy.com. Those two sites (and their associated magazines) have very useful star charts that you can customize for your location. If you have an iPhone or an iPad, you can get a wonderful app called Starmap. (Disclosure: I’m working on a project for these guys, but I was using their sky maps (free of charge on their site) long before they contacted me to work with them.)  I also very much like Skymaps, which provides both northern and southern hemisphere charts.  I also wrote about some good astronomy books and apps just before Christmas — check them out  here and here if you’re looking for some more extensive, tree-based information about where to look during your sky gazing sessions.  Now, get out there and check out the sky!  (Just be sure and dress for the weather!)
