Black moon set to rise this week in 'rare' lunar event - but what is it?

A 'rare' black moon is set to rise tonight/ Saturday morning– but what exactly is the lunar event and will we be able to see it?

 

'Black Moon Rising' may sound like the title of an apocalyptic sci-fi film but the astronomical event is unlikely to signal the end of the world, despite the concerns of some doomsayers.

What is a black moon?

 

From blood moons to strawberry ones and those of the ‘super’ variety, it can be difficult to keep up with all the different names given to the Earth’s natural satellite.

 

The latest causing excitement among skygazers is the so-called black moon, however there are several definitions about what it actually is.

 

Most experts agree the term black moon refers to the second new moon in a calendar month.

It shouldn’t be confused with a blue moon, a phenomenon that occurs when there is a second full moon in one calendar month.

 

Joe Rao from space.com explains: "A second full moon in a single calendar month is sometimes called a blue moon. A black moon is supposedly the flip side of a blue moon; the second new moon in a single calendar month." Scissors-32x32.png
