  • International Observe the Moon Night – September 19th

    Posted on September 14th, 2015 Lynn Powers No comments

    Join SMAS on Saturday September 19th from 6:00-7:30 p.m. at the Emily Dickinson Elementary School playground for an evening of activities and observing the Moon.  This is the 5th year that SMAS has participated in the global event.

    In 2012, students from Emily Dickinson were chosen as the winners of the NASA contest to name the twin probes from the GRAIL mission.  The school was given a telescope so students could continue to observe our dark skies and the Moon.

    Students in the 4th and 5th grade will also be treated to an up close look at Apollo lunar samples.  During the 6 Apollo missions, 800 pounds of lunar dirt and rocks were brought back.

    Save the date!  August 20, 2015. 7:00 p.m. at the Hagar Auditorium.

    “From the Big Bang to Black Holes: Time, the Universe, and Everything”
    Speaker: Janna Levin

    Professor of Physics and Astronomy at Barnard College of Columbia University
    Author of “How the Universe Got Its Spots” and “A Madman Dreams of Turing Machines”
    And a link to Janna’s TEDx talk:
    Janna Levin: The sound the universe makes | Talk Video |
    We think of space as a silent place. But physicist Janna Levin says the universe has a soundtrack — a sonic composition that records some of the most dramatic events in outer space. (Black holes, for instance, bang on spacetime like a drum.) An accessible and mind-expanding soundwalk through the universe.

The other was taken out at the Cottontail Observatory by Joe Witherspoon.  Thanks for sharing your pictures.  Also, take a look at the article in the Bozeman Daily Chronicle about the 6/22 event

  • NASA needs your help!

    Posted on April 23rd, 2015 Lynn Powers No comments

    When NASA’s New Horizons spacecraft flies by Pluto this July, the spacecraft’s high-resolution cameras will spot many new landforms on the dwarf planet’s unexplored surface.  There could be mountains, craters, rilles, valleys and, of course, the unknown.

    They are all going to need names—and NASA wants you to help.

    The public has until Friday, April 24 to help name new features on Pluto and its moons.  The naming campaign was announced in March, and now it is being extended because of widespread interest.
