This is Bloody Moon

My Premonition: The last day of the month the Moon will turn red with blood!…. or rather will appear red with light passing through our atmosphere. I know wayyyy less cool but still a sight to see! The reason the Moon looks red to us is similar to why during the day the sky is blue. Our atmosphere scatters blue light and red passes through. Since during the Eclipse the Earth blocks out the Sun, the only light hitting the Moon is what has passed through the Earth’s atmosphere, or red light.

On January 31st, there is a total lunar eclipse. This is when the Earth passes between the Moon and the Sun and casts a shadow on the Moon. This eclipse is visible in Asia and Australia in its entirety, North America, Europe and some parts of Africa and South America will get to see parts of it. To better explain this, here is the map of what portions of the Earth will be facing the Moon during this event. Just to note the penumbra is the outer portion of the shadow (or the hazy gray edges) while the umbra is the inner sharp dark portion of the shadow (much easier to see). If you want some animations to explain the eclipse, visit Time and Dates website here.
