After marking the start of meteorological fall, nothing is more seasonal than looking up and seeing the bright red blood moon; and this year on September 7th, some people across the globe were able to actually see it. Here's some dazzling video from many different countries who were actually able to see it.
The blood moon is a phenomenon that occurs twice every three years globally. It'll happen when Earth passes directly between the moon and the Sun, also known as a total lunar eclipse. This process is also known as Umbra. This, in turn, blocks out all the direct sunlight from the moon. During a blood moon event, sunlight that passes through Earth's atmosphere gets scattered. Light with shorter wavelengths, such as blue and green, scatters, so their light is not reflected off the Moon, while colors with longer wavelengths, such as red and orange, are able to reach the Moon.
While this phenomenon is impressive to see in person, atmospheric conditions actually play a role on the shade of the blood moon. For example, things like wildfire smoke, dust or even pollution can deepen the red shade of the blood moon, making it more striking in appearance.
Unfortunately, blood moon events aren't always visible worldwide. Being that the window of time the Earth passes in between the Sun and the moon is only 83 minutes, only certain spots can actually see the blood moon. In the window, the other half of the world is still in daytime! This most recent event, the blood moon was only visible in countries like Europe, Africa, Asia and Australia. Looks like the Americas had to sit this one out!
Not all hope is lost, because the next predicted full lunar eclipse will actually be visible from North America! This will be visible in both North and South America, Australia and East Asia!
