Stars Above Mountains An Outreach Program Linking Nature and the Sky A modest-sized telescope at one of the main AMC lodges, Highland Center, was used day and night to get people looking ‘up’ Douglas Arion, PhD Professor of Physics and Astronomy, Carthage College Director, Carthage Institute of Astronomy President, Galileoscope LLC darion@carthage.edu You, the reader, are a member of the choir. No one reading this needs to be convinced that the sky is important, and no reader needs to be told how connected we all are – as individuals and as inhabitants of Earth – to the entire Universe around us. But the vast majority of the public doesn’t think that way, and, frankly, if we, the converted, don’t do something about that nobody else will. My professional life is now dedicated to solving that problem – getting the public to understand, at a deep level, how important the Universe is to their own existence. How to achieve that aim? We need to provide people with real information – so they know what is out there and how it connects. And, we need to give them a moving experience, so that they will internalize and feel the connection. We’ve put together a partnership between the Carthage Institute of Astronomy at Carthage College (where I am on the faculty) and the Appalachian Mountain Club (the AMC). The AMC is the nation’s oldest outdoors and nature organi34 www.AmateurAstronomy.com zation, founded in 1876. They manage trail systems, lodges, and high mountain huts, and conduct many educational and outdoors programs throughout the northeast. Over half a million visitors a year take part in AMC activities. But, until we got involved with them, the programming reached from the ground to the mountaintops – and didn’t include the sky. So, this partnership is perfect – the AMC already has a large nature-oriented audience, and we have expertise in astronomy and outreach, and students who are trained in astronomy and telescopes to work with the public. Perfect! We received financial support from the National Science Foundation, which has allowed us to acquire more equipment and to support undergraduate students who intern over the summers here in northern New Hampshire. Donors have provided us with resources for additional gear, including several 4.5 inch Starblasts that are installed at four of the high mountain huts. Celestron was very generous to provide us with one of their high-end mounts, on which we put one of our aging, but fully functional, C11 tubes for our main outreach telescope. Add to that a quiver of equipment from my collection, including an 80mm carbon tube refractor (which, with a lightweight mount, is hike-able up into the mountains), and a PST solar telescope, and we have a reasonable collection of optics to show people the Universe. We also utilize a dozen tablet computers, each of which has Summer 2013 Issue # 79 Left: A youngster gets to look right at the Sun, safely!! Right: A great way to capture attention and draw audiences is to do daytime solar observing – as this hiker does next to Greenleaf Hut just below the summit of mile-high Mt. Lafayette, guided by intern Zach Troyer. planetarium software and a variety of other apps to connect people with celestial happenings, along with green laser pointers so participants can point to, and be pointed to, celestial sights. Our program has a number of major components. We work with several different audiences: • Members of the public (our primary audience), who (a) pass through AMC facilities; (b) attend AMC events; and/or (c) visit and stay at the high mountain huts • AMC staff and volunteers, whom we train in astronomy so they can include it in their ongoing programs • Undergraduate astronomy and physics students, who develop skills in engaging the public, giving presentations, operating telescopes, and knowing the night sky. There are several differences between the programs that we conduct and what is typically done in outreach. First, I’m not only an ATM and an amateur observer, but I’m also a professional astronomer (which means I get to use big telescopes that you don’t get to look through, which is scientifically useful but not as much fun as gazing into an eyepiece!). This has a benefit in credibility with the audiences. Second, the content of our presentations is aimed at showing and explaining the intricate connections among everything in the Universe. Sure – there is the usual ‘we are starSummer 2013 Issue # 79 dust’ content, where we talk about how AGB stars and supernovas are responsible for providing all of those heavy elements we need for life. It’s important to get people to understand that large mammals (i.e., us) are here only because an asteroid happened to impact the earth 65 million years ago, taking out those meat-eating dinosaurs, and affecting evolutionary patterns. But, most people don’t realize the continuing impact of cosmic rays (higher cancer rates for long haul pilots, for example), or that animal coats change because of shortening daylight, not lower temperatures (and, indeed, many of these animals are dying off because they are changing to white and, with climate warming, now do so in a background that is no longer snow covered). People don’t know that the solar spectrum and the color sensitivity of the human eye have the same wavelength dependence. These, of course, are not coincidences – we (and the other life forms on Earth) have evolved to fit our environment. The Earth is a ‘goldilocks’ planet – formed in the right area of space to have the right mix of elements, at the right range from a star of the right temperature, for the world we know to exist as we see it. The pictures accompanying this article show many of the things that we’re doing. First – we conduct workshops for all of the AMC staff who engage the public. Most of these individuals are experts in one or more areas of nature – www.AmateurAstronomy.com 35 Nightly observing is conducted by the students, and having a go-to mount makes it much easier to slew from object-toobject quickly, essential when there are long lines of people, and it’s already late (remember that northern NH is at 45 N Latitude, so it doesn’t get dark until late during early summer). The students discuss each of the objects shown in the context described earlier. This is not just a ‘look at this nebula….’ observing. This is an opportunity to show people parts of the Universe they haven’t seen, and explain to them how those kinds of objects have or do affect them. It’s important for people to realize that planetary nebulae are a source of mid-weight atomic species that are critical to formation of a planet (like ours). Showing Albireo, for example, is an easy way to discuss star colors and temperatures. But here we then explain how the Sun’s temperature is critical to the type of light we receive and the distance at which the Earth can be located to have a temperature where water can exist as solid, liquid, and gas simultaneously – the right environment for our kind of life to exist. The Moon? How have impacts affected the formation of life on Earth? As I hope you realize, we have tried to make sure that every experience each of our visitors has is tied to something that they will actually understand and feel, and motivate them to both learn more and to act differently. A young family gets to see the Sun for the first time, at a session we did at the AMC’s Pinkham Notch center. plants, animals, geology, and meteorology – but are generally not trained in astronomical topics. The workshops have been very successful in both informing and training them, as well as exciting them about the stellar canopy they see. We’ve already seen these individuals add astronomy topics to the content they deliver to AMC guests. We have a group of student interns from Carthage who are well versed in astronomy. All of them are required to have done research with myself or another member of our department – and all have had at least one observing experience with me at Kitt Peak or the Steward Observatory, so they know what real observational research is like. Because they carry the major burden of providing astronomy experiences to visitors to the AMC, they need to be experts – they can’t be the typical college intern who is only a gopher or helper. These students set up and operated telescopes all day and into the evening, whenever it was clear (which, most unNew-England-like, was most of the time this past summer!) We have found that solar observing – both white light and hydrogen alpha – is extremely engaging to neophytes. Few if any of have ever observed the Sun before (most certainly not in H-alpha), and in fact have been told not to look at the Sun, so this is a special experience. They generally are amazed at seeing sunspots and prominences, and are particularly blown away by the sheer size of these phenomena, when described in terms of Earth diameters. The daytime observing draws in many passers-by, who often then attend one of our more formal programs, or who at least return in the evening to observe through our telescopes again. 36 www.AmateurAstronomy.com This past summer we conducted weekly public lectures (with observing following) at the AMC’s Highland Center lodge. We drew good audiences – and had great feedback and lots of questions, signs that they were actively engaged and interested in what we presented. There isn’t enough room here to fully describe the content of the presentation, but, briefly, we cover the following: • Distances and scales (how big and how far) • Numbers of stars and galaxies (how many) • The evolution of the Universe (how long) and the events that allow our kind of life to exist • Extra-solar planets and life in the Universe • How our lives and the world around us connect to events in space, in the past, present, and future • Dark Skies Awareness and Preservation • And a final punch line aimed to change the attitude of audience members, summarizing the scales, sizes, and linkages, and why we, as a species, need to change our behaviors – the Pale Blue Dot. Following the major presentations we have several smaller sessions, each managed and run by one of the students. One is on telescopes and telescope operation; a second is on how to find things in the night sky and the great apps available for astronomy; and the third is an in-depth presentation on dark skies preservation. This last area is critical, and has been very, very effective with this audience. Of course, those who participate in AMC activities are already nature and preservation oriented, but they don’t know about the wide range of impact that poor lighting has on crime, health, and animals, besides the obvious economic costs involved. Throughout the summer we also conducted programs at the Summer 2013 Issue # 79 The high mountain huts along the Appalachian Trail in the White Mountains of New Hampshire are great sites to do public programs….if you don’t mind hiking a telescope up long, steep trails! Here this year’s student interns, KelliAnn Anderson, Coty Tatge, and Zach Troyer, pose above Lakes of the Clouds Hut – high up on the shoulder of Mount Washington. Dark skies preservation is an important part of the programming. The topic resonates with visitors who are already nature oriented, but don’t know about light pollution and its insidious effects. These sessions, conducted by KelliAnn Anderson, were very successful. AMC’s high mountain huts. These programs were similar to those conducted at the lodges, but we utilized tablet computers to display our presentations, as there is no projection capability up in the mountains. The tactile connection for the audience seemed to be effective at engaging them, and they were very excited to then take the tablets out under the sky and see if they could identify stars, planets, and other phenomena. We couldn’t, obviously, hike an 11” SCT up five thousand feet on five miles of mountain trail – which is why I built up a system consisting of a Stellarvue 80mm refractor and a Universal Astronomics micro mount on a carbon fiber tripod, which I can fit into a pack and hike, along with clothes and other gear, up to the huts. There are eight of these huts, separated by a days hike along the Appalachian Trail. Each is self-sufficient, using wind and solar power, and is operated by a team known as hut ‘croo’. The croo members are all wonderfully energetic, and really got into the chance to know more about the sky and to share it with visitors. The huts are beautiful structures, and the breakfasts and dinners that are served are fantastic. High up and in wilderness, the skies at the huts are as dark as can be found in the White Mountains area. Amazingly, one can still see sky glow from some of the local towns, even those that are relatively distant. That’s a great object lesson for our audience, who can see the extent to which even smaller communities can be contributing to light pollution. The hut audiences are great – they’re captive! We set up our telescope with a Herschel wedge for solar observing in the afternoon. After a scrumptious dinner, guests get to hear our presentations and then go outside and observe. We get to stay at the huts, too, so we can engage with the guests in the evening and the next morning over breakfast. The students and I were always inundated with questions and positive comments every morning. We know we’re having a great Summer 2013 Issue # 79 effect on these audiences. One of the other important things we’ve done is a very extensive evaluation and assessment activity. Each of the participants in one of our ‘formal’ programs is asked to fill out a questionnaire, which was formulated with the assistance of Prof. Wayne Thompson in Carthage’s sociology department. We’ve learned a lot from the responses to these questionnaires, and our program next year will be even better thanks to what we’ve learned. But, more importantly, the responses let us know that those who have gone through our programs really have changed the way they look at things, and the way they feel about themselves in the big picture. We hope that the behavior changes they talk about in the evaluation become permanent parts of their lives. We’ve completed one year of our program, and have resources to run it for at least two more years – and we hope for decades to come. Working as an individual with a couple of students, we reached over 3000 people in just a couple of months, and many others were touched by AMC staffers through their own programs during the summer. We want more and more people to have the experience we’re trying to provide, aiming for 5000 this coming year, and hopefully 10,000 the next. We need to expand the ‘choir’ – and get more and more people involved in promoting a world view that incorporates a lot more than just their world! This coming year’s program schedule is shown on the AMC website at www.outdoors.org/astronomy, as well as the site for the Carthage Institute of Astronomy at www.carthage.edu/astronomy. We hope that if you have the chance to be in New England you’ll join us, and also tell others about the wonderful programs that the AMC puts on. www.AmateurAstronomy.com 37
