We've had blood rain, a super blood moon, a very disappointing blue moon, and now a sinister-sounding 'black moon' is coming to our skies tomorrow. It might sound like a 'Twilight' sequel, but a black moon actually refers to the rare occurrence of two new moons in a single month. The last one happened in 2014, and the next one won't be until 2019, so it's not something you get to see every day. In fact, it's not something you can see at all. A new moon occurs when the moon's orbit takes it between the Earth and the sun, and the Earth-facing side of the moon is fully in shadow. Or, to put it simply, it's when the sky is really, really dark. But on the plus side, all that darkness means it'll be perfect conditions for stargazing – just don't expect to see the moon.
