With two presentations and a chance to view the night sky in the nearby recreation field, the Hi Desert Nature Museum spotlights desert astronomy. The 4 PM presentation by local astronomer Steve Caron is "Light Pollution and the Night Skies" and at 5 PM doctoral student Niyati Desai presents "How to See a Planet." Beginning at 7 PM at the Community Center Ballfield, telescopes will be available for a look at the night skies. While the event is free, donations will be appreciated.
