Have you seen a Blue Moon? Our last Blue Moon came on October 31, 2020.
It was the night of Halloween, and Mars was near the Blue Moon. Mars was close to Earth and very red then. But that full moon - like most Blue Moons - was blue in name only. We called it a Blue Moon because it was the 2nd of 2 full moons in a calendar month. Now another sort of Blue Moon is coming up. It's the 3rd of 4 full moons in a season (the time between a solstice and an equinox). The next Blue Moon is of this sort. It'll happen on August 22. And, by lucky coincidence, the moon will be near planets again, this time Jupiter and Saturn. 🌕
