Stargazers have several celestial treats in store for March, from a comet and a partial lunar eclipse to the vernal equinox heralding the first day of spring. Coloradans should have some gorgeous nighttime views, weather permitting, and those in the Â鶹¹ÙÍø area can attend regular open houses at the University of Colorado at Â鶹¹ÙÍø each Friday in March, except March 28, and April, according to astronomer Katy Garmany, director of Fiske Planetarium and Sommers-Bausch Observatory.
