🌕 Full Moon, Total Lunar Eclipse, and Lantern Festival

🌕 Full Moon, Total Lunar Eclipse, and Lantern Festival

11:37am

Event

The full eclipse is visible from the western United States and Canada, Japan, eastern China, and eastern Australasia. Speaking of China: the Lantern Festival (Yuanxiao Jie) occurs at the end of the lunar year, concluding Chinese New Year festivities. The night sky is filled with colorful lanterns, symbolizing good fortune and family reunion. Traditionally, people celebrate by displaying lanterns, solving riddles written on them, and eating sweet rice balls (tangyuan), symbolizing unity and wholeness. According to legend, the Jade Emperor, ruler of heaven and usually celebrated for being a great friend to humanity, became enraged when a town killed his favorite sacred goose. In his fury, he planned to destroy the town with a storm of fire on the 15th lunar day. The Jade Emperor's daughter, sympathizing with the innocent people, warned them of her father's plan. The townspeople then lit lanterns throughout the town and set off firecrackers to make it appear as if the town was already burning. Fooled by this, the Jade Emperor decided not to send down the fire. Pyromaniacs, get in on the fun! Here's a video that shows you how to make your own flying fire lantern: https://www.youtube.com/watch?v=mHyAefvWpXA

Canton's Birthday!

Canton's Birthday!

Event

Who's Canton? He's the fellow who updates your astronomy calendar (full moons, equinoxes, meteor showers, etc.) from his laptop in the high mountains (and dark skies) of Santa Fe, New Mexico. It's his birthday today! https://cantonbecker.com/astronomy-calendar/#credit This astronomy calendar is an effort of love and no reciprocity is expected. But for the first time since the calendar started in 2007, donations are now welcomed if you'd like to help with hosting costs or buy Canton a coffee. To donate, or to say thank you, or to report an error (!) please visit the link above.
