Citizen Astronomers

The Research Amateur Amateur

I saw a story making the rounds yesterday about how citizens who aren’t necessarily scientists are making great strides in some areas of research simply because they’re interested in the science. I think that’s always been around in some form or another, and none more so than in amateur astronomy.  There have always been legions of dedicated amateurs watching the sky and making contributions to science — although there have been more of them in the past 20 or so years.  Astronomy was largely performed before the 20th century by dedicated amateurs (who were often quite well trained). Today there are amateur observatories out there that rival (and sometimes surpass) many university facilities, and their owners are making valuable contributions to astronomy research.

When I first got to graduate school, I worked with a number of well-trained amateurs who sent in gobs of images of Comet Halley during its closest approach.  At that time, some professional astronomers scoffed at the idea of amateurs making any kind of contribution, but they were proved wrong. And wildly so.  Take, for example, all the folks who are discovering and providing amazing images of comets and asteroids. They’re helping fill in our gaps of knowledge about what populates the solar system.

Amateur astronomy work isn’t limited to the solar system. Dedicated amateurs have been doing work studying starbirth regions, variable stars, gravitational lensing, gamma-ray bursters, and the list goes on and on.

Every night and day (for solar observers), amateur astronomers train their telescopes (and other instruments) on the sky and make observations that add to the “corpus” of knowledge humanity has about the universe. I remember once hearing a colleague of mine comment that amateur astronomers can do observations that professionals couldn’t do, either because the big observatories are over-subscribed, or because they can’t point those big telescopes so close to the ground (or the Sun). That same colleague also pointed out that if professional astronomers who couldn’t get time on the big scopes knew there was so much “free glass” out there to be used, they’d be rushing to adopt amateur astronomers and their observatories. That was 15 years ago. Today, the amateur and professional communities are indeed cooperating more than ever — largely because dedicated amateurs have the equipment and know-how to perform observations that were once solely the province of the “big” (at that time) facilities.

So, long live the amateur astronomer!  It’s a long and honorable avocation!

Finding Fascinating Things

Yesterday I talked here about space agencies as sources of cool information about astronomy and space science. Today, I’m going to walk you through a collection of just some of my favorite astronomy observatories. First off is one of my favorites — the Gemini Observatory, which operates out of two sites in Hawai’i and Chile.  I’ve beenworking with them for several years now as an associate editor of GeminiFocus, their twice-yearly publication.

Next is the Space Telescope Science Institute, which operates the fabulous Hubblesite.org web page.  It’s home to more Hubble Space Telescope material than you can possibly imagine, and good for hours of surfing pleasure!  It’s one of my first stops every day or so, just so I can find the latest and greatest from one of my favorite telescopes.

The Hubble Europe folks also have an amazing array of information on their pages, so I usually check them out every couple of days, too.

After that, I usually check out the Chandra X-ray Observatory Web pages for the latest in x-ray exploration of the cosmos. Then, I head over to the Cassini Equinox Mission web pages for my Saturn system fix.  Following that, I check out the latest at Mars, which covers the Spirit and Opportunity rovers, as well as any of the orbiting missions to the Red Planet.

The European Southern Observatory usually has something new every few days and is well worth a few hours of browsing.

Next stop is often the National Radio Astronomy Observatory, which gives you a nice radio-wave view of the cosmos.  Beyond that (and moving across the electromagnetic spectrum), I try to pick up the latest and greatest from the Spitzer Space Telescope, our orbiting infrared eye in the sky.

Now, mind you, I can’t do that much surfing every day — and, indeed, there are many, many MORE sites out there, like the MESSENGER mission to Mercury, and the New Horizons mission to Pluto, and the fabulous Kepler mission to look for Earth-like planets (which just launched this year) and on and on… but, these are a good start on the multitudes of astronomy and space science sites that are out there, just waiting for you to find them.

Chances are you could spend days browsing through just these pages, and learning a LOT about the solar system, our galaxy, galaxy clusters, interactions, and the large-scale structure of the universe just from these sites. And, if you follow the many, many links to other places from these sites, you’ll be surfing the cosmos for days… weeks… months.

It’s worth it, I say. So, check ’em out. And, in a future installment, I’ll bring you some more cosmic web sites by other observatories, scientists, and science writers — all ready for you to visit and enjoy!!
