Happy Fall Equinox! Our star, the Sun, is directly over Earth’s equator today, creating a roughly equal amount of daylight and nighttime hours (equinox comes from the Latin aequus which means equal and nox means night).

Curious to know more? Plan to join us a few days before the actual date for our Colorado Skies: The Fall Equinox star talks on September 19 and 20. We'll also explore the constellations of autumn.
