Babe Among the Stars: Black Moons and Cosmic Dancing

Mortal as I am, I know that I am born for a day. But when I follow at my pleasure the serried multitude of the stars in their circular course, my feet no longer touch the earth - Ptolemy
Black Moons and Cosmic Dancing
Coming up this month in the eastern time zone is a so-called 'black moon', which is a second new moon in a calendar month. Thanks to different time zones, Europe's black moon will occur in late October. There's also cosmic dancing between the Sun and Moon which can only be seen from our vantage point on planet Earth. This beats anything from Strictly Come Dancing. How lucky we are!
September 2016 Diary Dates
This month there is an annular solar eclipse, that's when the Moon passes in front of the Sun when the Moon is smaller, and there is a glorious 'ring of fire' from the background Sun. Unfortunately for the rest of the world it's only visible from Africa. We're sure to see plenty of images though, here's a previous one from APOD. The Sun and Moon continue their cosmic dance later in the month when they come together again for a penumbral lunar eclipse. Luckily this will be viewable from Europe, Africa, Asia and Australian regions (see local astronomy websites for details). There is a perfect description and image of the penumbral shadow at APOD.
