There are events that happen once in a blue moon\u2014but events that happen once in a black moon occur just as often.<\/p>\n
This weekend, the world will experience a black moon. The moon itself won\u2019t actually turn black.<\/p>\n
The term \u201cblack moon\u201d refers to either two new moons in the same month or four new moons in a single season.<\/p>\n
The summer of 2025 will have four new moons, and the third of them this season receives the black moon designation.<\/p>\n
Black moons are rare occurrences. A new moon happens about every 29.5 days. Since most months are 30 or 31 days long, and a season is roughly 91 days, a black moon usually requires a new moon to fall on the first day of a month or season.<\/p>\n
A blue moon happens just as often\u2014when there are two full moons in a month or four in a single season.<\/p>\n
One thing that makes a black moon more exciting for astronomers than a blue moon is that the new moon phase offers darker skies for viewing stars and planets. In contrast, the bright light of a full moon tends to wash out other objects in the night sky, making them harder to see.<\/p>\n
The next full moon will occur on Sept. 7 and will coincide with a lunar eclipse. Unfortunately for Americans, this eclipse will happen during the daytime, meaning only viewers in Asia, Europe, and Africa will be able to see it.<\/p>\n
This new moon will also bring a partial solar eclipse, but that event will only be visible in parts of the Southern Hemisphere.<\/p>\n","protected":false},"excerpt":{"rendered":"There are events that happen once in a blue moon\u2014but events that happen once in a black moon…\n","protected":false},"author":2,"featured_media":90726,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[23],"tags":[49,48,66,306],"class_list":["post-90725","post","type-post","status-publish","format-standard","has-post-thumbnail","category-space","tag-ca","tag-canada","tag-science","tag-space"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/posts\/90725","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/comments?post=90725"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/posts\/90725\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/media\/90726"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/media?parent=90725"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/categories?post=90725"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/tags?post=90725"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
