Can Anybody Do Astronomy?

Sure, Why Not?

When I was watching the Mars Phoenix lander festivities the other night, I thinking about all the scientists and their students who are (as we speak) working with the incredible rush of data being returned by the mission. And, it occurred to me that this kind of science is something I wish everybody could experience once in their lives. It’s a heady feeling, looking at images and data and realizing that you’re finding something new and interesting to share with the rest of the world.

Amazingly enough, discovery in the universe is NOT limited to scientists, although they’re the ones best trained to undertake the years of work that it takes. But, as I learned in my days on the Halley Watch project, there are a lot of amateurs out there who are also well-equipped (both mentally and with access to equipment) to discover unique things in the universe. Much of the work I did on the Halley Watch project (which culminated in an atlas of Halley images that we used to study the solar wind’s influence on comet plasma tails) came from amateur astronomers who submitted images for study. And they were first-rate images, exactly what we needed.

Today, I got a story about an amateur astronomer named Richard Miles, who used a telescope in Australia that is part of the Faulkes Telescope Network to look at an asteroid called 2008 HJ. His work, conducted via the Internet from his home in Dorset, England, proved that this newly discovered asteroid is rotating (spinning around an axis) once every 42.7 seconds. That makes this object the fastest-known rotator in the solar system. In asteroid studies, this is a big deal, since these little worldlets and chunks of solar system debris are hard to see, let alone figure out how fast they’re rotating!

I am constantly amazed at what there is yet to learn in the universe. What this find tells me is that there’s plenty of discovery in the universe, and it’s not all limited to folks in the big labs. There are an increasing number of robotically controlled telescopes available to interested and well-prepared amateurs who want to do some research. As we used to tell the participants in the Halley Watch, there’s room for everybody in the cosmic pool — from first-time stargazer to well-equipped amateur to professionally trained researcher. Jump on in and take a swim!

Stalking the Wild Supernova

Rule 1: Be Prepared

Rule 2: Use Lots of Observatories

Satellite images of galaxy NGC 2770The big news about Alicia Soderberg and Edo Berger’s observations of a supernova just beginning its explosion is one of those great stories that illustrates the saying “Chance favors the prepared mind.” A few months ago when both authors were writing an article about their find for GeminiFocus (a magazine on which I’m associate editor), I marveled at how lucky these two were. But, they were doing more than just being in the right place at the right time. They also had the capability to reach out and grab use of several observatories to get the best multi-wavelength view of the supernova (which blew up in the galaxy NGC 2770 (which lies some 88 million light-years away from us). Of course, SWIFT saw the first x-ray emissions from the supernova, and the astronomers noticed that right away. In short order, the pair alerted the astronomy community, and soon the orbiting Chandra X-ray Observatory, the Very Large Array radio telescope in New Mexico, the Gemini North and Keck 1 telescopes in Hawai’i, two telescopes at Palomar Observatory in California, and a telescope at Apache Point in New Mexico were all looking at this outburst.

The combination of observations from all this observatory “firepower” pins down the moments when the first x-rays began streaming from the star. Eventually this information will help astronomers understand the moment-by-moment events that occur when a massive star finally explodes as a supernova. It’s a look at stellar death throes that wouldn’t have been possible even a few years ago. Chance — and a lot of really good telescopes — really do favor the prepared astronomers who got this chance to look into the jaws of star death.
