Early tomorrow morning, the last total lunar eclipse for the next three years will occur 🌑 A lunar eclipse happens when the Sun, Earth and moon align so that the moon passes into Earth's shadow. In a total lunar eclipse, the entire moon falls within the darkest part of that shadow and takes on a reddish hue. You don’t need any special equipment to observe a lunar eclipse, although binoculars or a telescope will give you a better view and help you see the red color! | National Geographic TV
