    The Stars Still Talk to Us…
    Next Tuesday, I will attempt to share some fun of the astronomical sky-connections of the Big Horn Medicine Wheel with families at the public library.  Please come! and share this with your friends.  –Ivy

    Family Science Night: Star Wheels  at the Bozeman Public Library on February 19,2013  6:30- 7:30 pm

    Free and open to the public

    In this family science workshop, we will create our own astronomical medicine wheels, patterned after the Big Horn Medicine Wheel that resides at nearly 10,000 ft elevation in the Big Horn Mountains just south of the Montana border.  The Big Horn Medicine Wheel, whose glowing white rocks under starlight and moonlight,  are able to convey the actions of celestial objects throughout vast expanses of time and space.  We will create smaller wheels that can be useful in connecting our own home to the Sun, stars and planets, bringing increased delight and meaning to our evening skywatching. Family members may make individual wheels or work on one together. All ages welcome.

  • Final push for Building Bigger Skies

    Posted on January 27th, 2013 Lynn Powers No comments

    The planetarium remodel is almost complete. The final push for raising the last $60,000 of the $1.5 million will take place this coming week with the help of a telethon on KBZK.  During the local 10 p.m. news, members of SMAS, MSGC, MoR, and MSU will man the phones.  When the Taylor Planetarium reopens on March 2, 2013 it will be one of the first planetariums in the US to have an Evans and Sutherland Digistar Five digital planetarium projector. It is the only public planetarium in the state of Montana and in a 400 mile radius.  We are lucky to have such a great facility in our backyard.  Please support the telethon!

  • 2013 Winter Lecture Series

    FROM THE BIG BANG TO GALLATIN VALLEY: The Cosmic biography of atoms
    Shane L. Larson
    Department of Physics, Utah State University

    Everything we see around us is composed of the same fundamental building blocks — the 92 naturally occurring chemical elements.  The most abundant element in the Cosmos is hydrogen, most of which was synthesized in the Big Bang.  But where did all the atoms we see around us come from?  How did the original hydrogen in the Universe evolve and mutate into carbon and calcium and iron and gold and all the other elements that we can easily find by breaking open rocks and other common Earthly objects?  The answer is intimately tied to the lives of the stars. They are born out of loose nebular gas and dust, burn their hydrogen fuel into heavier more complex elements, and ultimately explode in one of the most devastating cosmic events known — a supernova — dispersing the elements out into the Cosmos.

    In this talk, we’ll consider the biography of an atom, from the Big Bang to the Gallatin Valley, and explore how the evolution and changes of a single atom can be traced and followed in the lives and deaths of stars.  We can trace the lives of the stars through what can easily be seen with small telescopes and binoculars, and will navigate our way through the night sky to visit nebulae, star clusters, binary stars, and supernova remnants to tell our tale.

  • Light Fight

    A recent article in the Bozeman Daily Chronicle is generating a good debate about our dark skies:

    Professor says Baxter sign affects optics research, local companies

    Sign owner says he will turn it off at closing time each night.

    AMANDA RICKER, Chronicle Staff Writer, Posted: Tuesday, January 15, 2013

    A professor and optical technology expert at Montana State University says the relighting of the “Hotel Baxter” sign downtown affects MSU’s optics research and Bozeman’s growing optics industry.

    Meanwhile, the sign’s owner says he will try to alleviate some of the concerns by turning the sign off at 1 a.m. each night.

    Joseph Shaw, director of MSU’s Optical Technology Center and a professor of electrical engineering and physics, said light from the bright, red Baxter sign affects sensitive optical receivers being tested on the roof at Cobleigh Hall.

    “We’re sitting on one of the tallest buildings on campus, looking directly over the top of the Baxter,” Shaw said Monday. “It’s like somebody taking a competing light source and holding it up to get as close to our measurements as possible. I know they didn’t design (the sign) to do that, but that’s why it’s a particular problem.”

    Shaw said MSU researchers are inventing new sensors and using them to conduct research ranging from weather forecasting and climate studies to military sensing.

    “These sensors depend on being able to see into the night sky without a lot of extraneous light pollution,” he said.

    Further, Shaw said the research contributes to a growing number of optical technology companies in town, such as ILX Lightwave and Bridger Photonics. Since 1980, he said, more than 24 optics companies have set up shop in Bozeman. And in many cases, Shaw said the companies use technology or ideas developed in concert with the university.

    “So, if we impair the optics research at MSU, we are also impairing the health of the optics companies in town,” he said. “It isn’t an us-versus-them thing. It’s very much an issue that I think is important for the entire community.”

    Shaw said a recent study funded by the governor’s office found that Bozeman optics companies are an up-and-coming component of the Montana economy, as one of the few places in the state where there’s a significant amount of high-tech companies clustered together.

    Bozeman has significantly less light pollution than the average city, Shaw said. People can still look up at night and see the faint band of stars created by the Milky Way or the rare northern lights moving across the sky.

    The city of Bozeman does a better job than most cities in protecting dark skies, Shaw said, but a growing number of streetlights and improper lighting techniques are threatening that status.

    Shaw said in addition to affecting optics research, the Baxter sign and the increasing amount of light pollution in Bozeman affects the Montana Aurora Detector Network, which sends text and email alerts to stargazers when the aurora borealis is occurring.

    Proper lighting techniques include shielded fixtures that point the light down and away from the sky, reduced brightness and restricted color content, Shaw said.

    Shaw and David Loseff, the majority owner of the Baxter, have scheduled a meeting to discuss ways to compromise.

    “We respect the university and are sensitive to these issues,” Loseff said. “Our sign was a 1929 sign, which predated their current project, and I hope (Shaw) can be as sensitive to the history of the community and historic preservation.”

    Loseff said Monday he plans to turn the sign off each night at 1 a.m. when businesses close in the Baxter building. The sign is turned on at 5 p.m.

    Loseff suggested perhaps MSU’s equipment could be tested in more rural areas outside of town.

    “Bozeman is a large and growing community,” he said.
