Citizen Astronomy

It’s a Tradition to Carry Forward

Suddenly citizen journalism is a big thing on news sites. They want YOU to go out and film events happening and then “share” them with other viewers/readers. I think it’s kind of an interesting twist on the traditional journalistic practice of having reporters actually covering events and interviewing people on the scene.

In astronomy, we’ve had “citizen observers” since the dawn of time.  These days it’s called “amateur astronomy” and there are hundreds of thousands of people who devote some part of their time each week watching the sky, looking at the stars, and in some cases, discovering new things along with the “professionals.”

Amateur astronomy has a star-studded history (so to speak).  Back before Big Astronomy got Big Budgets to build Big Instruments (say, prior to the late 1800s and early 1900s), there was little practical difference between amateur and professional stargazers.  For a time, it was a rich man’s profession because wealthy folks had the shiny gold rocks to trade for building big telescopes.  But, things have changed since then, and while we have two divisions of astronomers these days — the ones who love what they do and get paid for it (and work with equipment paid for with taxpayer dollars/yen/yuan/Euros, etc.) vs. the ones who love what they do and do it for free — in some places, amateurs and professionals work together to make discoveries.  In fact, in many studies, professionals depend on amateurs to gather data. Some that come to mind are the American Association of Variable Star Observers (which is actually an international group) Center for Backyard Astrophysics, the International Occultation Timing Association, and others you can read about here.

For folks who aren’t interested in going the research route, even as an amateur, the International Year of Astronomy has a number of “citizen-oriented” activities planned, including a massive observation of the star Epsilon Aurigae in summer 2009, Globe at Night, Astronomy 2009 in Second Life, 365 Days of Astronomy, the Galileoscope and the Galileo Teacher Training Program, and many, many others. And, after you do all these things, you can get online and blog about your experiences or even publish videos of you and your friends and family doing stargazing and space science activities. That combines the best of both worlds: citizen journalism and citizen astronomy!

Hittin’ the Charts

Find your View of the Sky

It’s moving on toward autumn sky-viewing time here in the northern hemisphere (and early spring for the folks in the south). If you don’t already have a collection of star charts, or a program like Software Bisque’s TheSky, or a book or two about stargazing, you can always look online for any number of great free (or low-cost) resources to help you figure out what you want to observe. (If you’re interested in finding astronomy products, check out TheSpacewriter’s Store.)

A screenshot of the Sky View Cafe

So, browsing around online, I found a great astronomy resource today while I was trying to figure out what the skies would be like over the Caribbean later next year (for a lecture I need to give).  This one’s an interactive planetarium page called Sky View Café. You can use it with your Java-enabled web browser to find out what’s up tonight at your location. You can also download a desktop version for offline use. It’s the work of an imaginative coder named Kerry Shetline. Here’s a screenshot of the online interface, and it couldn’t be easier to use. Simply input your location and the date and time you want to observe, and it automatically takes the sky to the proper position. There’s an extensive and easy-to-understand help section, too.  Go take a browse through the starry sky before your next stargazing session!
