GOLDENDALE — Troy Carpenter will present “Lunar Exploration Via the Internet” at 7 p.m. Sunday.

The lecture, part of a Washington State Parks series of online astronomy lectures, will stream on Parks’ YouTube channel youtube.com/user/washington stateparks.

Weather permitting, participants will observe Earth’s moon in high definition and learn about the history of human and robotic exploration of our nearest natural neighbor.

Carpenter, an interpretive specialist at the Goldendale Observatory State Park Heritage Site, will also talk about NASA’s recent announcement regarding the discovery of water on the sunlit surface of the moon.
