  • The Gradual Sunset at the North Pole

    Today, we are going to be taking a look at the sunset for autumn, but we’re mostly going to be looking at it from the North Pole. However we’ll start with sunset from Ireland in late September. As the Sun sets, first it drops behind trees and buildings, then the horizon itself. We know the…

    Today, we will be looking at the sky for late September, especially around the day of the equinox.
