Sunset Meditation Planetarium Show & Retzer-led Night Hike
Soundbath
"Tonight and tomorrow night, peek at the moon to witness ""earthshine!"" Are you familiar with what earthshine is? Earthshine is a dull glow which lights up the unlit part of the Moon because the Sun’s light reflects off the Earth's surface and back onto the Moon. It is also sometimes called ""ashen glow"", ""the old Moon in the new Moon's arms"", or the ""Da Vinci glow"", after Leonardo da Vinci, who explained the phenomenon for the first time in recorded history. Earthshine is best seen a few days before and after a New Moon, right after sunset or before sunrise. Scientists studying global warming found that earthshine is more intense in April and May! Hopefully you will have the chance to check it out! SOURCE: timeanddate.com"
