![]() ![]() Not all places will be able to see the eclipse in its entirety. EDT (13:49 UTC) marks the end of the show. After that, the end of the penumbral eclipse at 9:49 a.m. After totality, the moon will be in a partial eclipse until 8:52 a.m. You might be out of popcorn by now, but it's worth it to stay for the rest of the eclipse. It's these reddish wavelengths that hit the moon, giving it an ochre color until totality ends at 7:18 EDT (11:18 UTC). This light travels through Earth's atmosphere, which filters out the shorter blue wavelengths but lets the longer reddish wavelengths through. This happens because the sun's light bends around the edges of Earth. ![]() During this time, called totality, the moon will look like it's rusty red. For roughly the next 14 minutes, the moon will be completely covered by Earth's dark umbral shadow, reaching the maximum eclipse at 7:18 EDT (11:18 UTC). Only a sphere could cast a round shadow from all angles, he reasoned.įinally, the total lunar eclipse will begin at 7:11 a.m. Aristotle realized that no matter where people saw the eclipse or whether the moon was high or low in the sky when they saw it, the dark umbral shadow was always curved. ![]() The Greek philosopher Aristotle (384-322 B.C.) also noticed that Earth's umbral shadow on the moon was curved during partial eclipses, and this helped him decipher that Earth was round, according to NASA. Because the umbral shadow's diameter is typically about 2.7x the moon's diameter, it appears as though a semi-circular bite has been taken out of the moon." "This is primarily due to a contrast effect because the remaining portion of the moon in the penumbra may be brighter by a factor of about 500x. "The lunar limb extending into the umbral shadow usually appears very dark or black," NASA reported. Unlike the penumbral portion, the partial eclipse is visible to the naked eye. This marks the beginning of the partial lunar eclipse. EDT (09:44 UTC), Earth's dark shadow - known as the umbra - will begin to cover the moon. "Thus, some fraction of the sun's direct rays continues to reach the most deeply eclipsed parts of the moon during a penumbral eclipse." "From within this zone, Earth blocks part but not the entire disk of the sun," according to NASA. Darkening from Earth's light shadow during penumbral eclipses is typically hard to see with the naked eye, NASA reported. ![]()
