On December 14, 2011 Ysleta Branch presented the program “Wonders of Astronomy”. Ysleta staff member, Martha Bocanegra was the host of this very informative program detailing our El Paso night sky. Astronomy is the study of celestial objects, a must for the serious stargazer. Martha revealed how the planets, stars, constellations, galaxies and other heavenly bodies interact and move about throughout the cosmos. Our patrons certainly left with an increased knowledge of the night sky.
