  • eXtreme Gravity – lecture

    Posted on March 2nd, 2017 Lynn Powers No comments

    MSU professor and astrophysicist Neil Cornish will present Cornish“Extreme Gravity,” at 7 p.m. Tuesday, March 7, at the Museum of the Rockies’ Hager Auditorium. A reception will follow.

    There are places in our Universe where gravity is so strong that it blurs the separation between space and time, and transforms matter into strange new forms. This the realm of extreme gravity. Gravity eventually causes stars to collapse, sometimes forming diamonds the size of the moon, other times forming mountain sized orbs of nuclear matter. The fate of the largest stars is even stranger, as gravity crashes matter out of existence to form a black hole – a region of space from which not even light can escape. Today we are able to explore the realm of extreme gravity for the first time using a new generation of telescope, one the size of the Earth, one that will soon be attached to the International Space station, and another that listens to the vibrations of gravity itself.


  • February 2017 Winter Lecture Series – by Dr. Ivy Merriot

    Posted on January 29th, 2017 Lynn Powers No comments

    Join SMAS on Friday February 10th starting at 7:00 p.m. at the Commons (Baxter Lane at Love Lane) for a free public talk by Dr. Ivy Merriot. Bighorn Medicine Wheel

    The Dance of Stars Above the Big Horn Medicine Wheel

     The Big Horn Medicine Wheel, an eighty-foot circle of stones at nearly 10,000 feet in the mountains of Wyoming has long been known to “point” to the Sun on the morning of the longest day of the year. Ivy Merriot, PhD will share her current research on astronomical medicine wheels, showing how these wheels mirror the stars above, giving us an enduring, accurate, and cosmo-tuned method of marking time and tracking cosmic events. The Wheel’s mirroring of the sky above creates a dynamic star chart you can walk inside of, like the holographic map room in Star Trek. With a skywatcher’s skill-set, any visible celestial object can be studied over time from this type of astronomical Wheel, the Sun, Moon, planets, comets, asteroids, etc. The stone design of these astronomical medicine wheels make them instruments as useful in visual astronomy today as they were five thousand years ago.

  • 2017 and the Great American Eclipse

    Posted on January 28th, 2017 Lynn Powers No comments

    On the morning of Monday August 21, 2017 a total solar eclipse will cross North America.  Screen Shot 2017-01-24 at 1.07.17 PMOnly those along the path of totality will experience the sun being totally blocked by the moon and the sky going black.  All others from Canada through the US and Mexico, and on down to Central America will experience a partial eclipse.  Here in Bozeman it will be approximately 95% coverage.  If you plan to go south into Wyoming or Idaho, you could experience totality. If you plan on staying here in Bozeman, be sure you have proper equipment to observe the eclipse.  For a better view click on the image:

  • ISS turns 16

    Posted on November 7th, 2016 Lynn Powers No comments

    920x920This week NASA celebrated the sixteenth anniversary of the International Space Station. From 1998 to 2011, space agencies from 15 different countries amalgamated to form what is to date, the largest ever structure in space. November 2, 2016 celebrates the continuous presence of humans on board.
    Here are some links that show the history of the ISS. Enjoy!

  • Free online Astronomy book

    Posted on November 3rd, 2016 Lynn Powers No comments

    We are excited to let you know about a national, non-profit project to develop a high-quality, introductory astronomy textbook that is free to students and the public alike. The publisher, OpenStax, is located at Rice University and supported by several major foundations (including the Gates Foundation.) They have already done over 20 free textbooks in other fields, used by hundreds of thousands of students around the country.

    With the help of over 75 astronomers and astronomy educators (several that I know), the textbook (cleverly named Astronomy,) has been adapted, expanded, and updated from earlier textbooks the three authors have written. The book is free to students in the electronic version, and can be custom printed on demand – at cost. Even more interesting, the book is open source, which means you can use it as is, or develop your own electronic version of it, selecting only the sections you want to read.

    Astronomy book

    Featuring such current topics as the results from the New Horizons exploration of Pluto, the classification of exoplanets from Kepler and other projects, and the discovery of gravitational waves, the book is up-to-date and peer reviewed. At the same time, it is written in everyday language specifically for non-science majors or amateur astronomers, with many analogies from students’ lives, clear diagrams, the latest color images, and occasional touches of humor.

    Math boxes throughout the chapters put topics on a quantitative footing for those who want to use math. Each chapter has math problems at the end. However, if you don’t use math, these boxes and problems can easily be skipped. Chapters also include suggested collaborative group activities, especially useful for discussion sections, links to web resources, biographies of astronomers, interdisciplinary connections, and much more.
