April 24, 2017 - Celebrate Astronomy Day

Celebrate Astronomy Day  This week, thousands of stargazers will be “bringing astronomy to the people” during semi-annual Astronomy Day events coordinated by the Astronomical League, an umbrella organization of over 240 U.S. amateur astronomy clubs. Science museums, astronomy clubs, planetaria, libraries, and nature centers will host special events worldwide—at decidedly non-astronomical sites like shopping malls, parks, and downtown centers—to acquaint people with local astronomical resources and facilities. This is a great chance to meet and learn from talented amateur astronomers like R. Jay GaBany, who captured this image of galaxy M83 in Hydra using an advanced half-meter (twenty-inch) telescope. Visit the AstroLeague.org website this week to learn more.
