Whoa...wait a minute? Say what? No, that isn't a typo! A somewhat unusual lunar event known as a Black Moon will occur this Friday, September 30th.
A Black Moon is when you have 2 new moons in one month. It is opposite to the more well known, Blue Moon when there are two full moons in one month.
Unfortunately, you will not be able to see the Black Moon since the Earth's facing side of the moon will be in its shadow. The last time we had a Black Moon was back in March of 2014.
According to NASA, "Black Moon" isn't even a scientific term. It also has been used to describe a month that doesn't have a full moon, or to describe a third full moon in a season that has four full moons.
By the way...there will not be a Blue Moon in 2017. The next one will be on January 31, 2018.
