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 Boulder area can attend regular open houses at the University of Colorado at Boulder each Friday in March, except March 28, and April, according to astronomer Katy Garmany, director of Fiske Planetarium and Sommers-Bausch Observatory.
