More and more eastern states will see the Moon set over the next hour as the eclipse progresses.Īt 4:49 a.m. At this point, the Moon will have just set in the most northeastern portions of the continental United States.

EST), the edge of the Moon will begin exiting the umbra and moving into the opposite side of the penumbra, reversing the “bite” pattern seen earlier. Details can be found below in the Teach It section.Īt 3:41 a.m. The potential for variation provides a great opportunity for students to observe and classify the lunar eclipse based on its brightness. Clouds, dust, ash, photochemical droplets and organic material in the atmosphere can change how much light is refracted into the umbra.

Should you decide to skip this part of the eclipse, you won’t miss much.Īs the Moon moves completely into the umbra, it turns a reddish-orange color. Because this part of Earth’s shadow is not fully dark, you may only notice some dim shading (if anything at all) on the Moon near the end of this part of the eclipse. The Moon will dim very slightly for the next 67 minutes as it moves deeper into the penumbra. EST), the edge of the Moon will begin entering the penumbra. will see the Moon set below the horizon as it exits Earth’s shadow in the second half of the eclipse.Īt 12:02 a.m. Viewers in the most eastern parts of the continental U.S. 8, 2022, which will be visible in North and South America, as well as Asia and Australia. Here's what to expect during the total lunar eclipse on Nov. The inner part of the shadow, known as the umbra, is much darker because Earth blocks additional sunlight from entering the umbra. (You have probably noticed that some shadows on the ground are darker than others, depending on how much outside light enters the shadow the same is true for the outer part of Earth’s shadow). The penumbra is less dark than the inner part of the shadow because it’s penetrated by some sunlight. The outer part of the cone-shaped shadow is called the penumbra. The Moon passes through two distinct parts of Earth’s shadow during a lunar eclipse. Here's how and where to watch one of the sky’s most dazzling shows when the Sun, Earth, and Moon align, creating a total lunar eclipse. These comparisons helped scientists determine the rate at which Earth’s rotation is slowing. When Hipparchus saw that the stars’ positions had indeed moved, he knew that Earth must wobble on its axis!Īdditionally, modern-day astronomers have used ancient eclipse records and compared them with computer simulations. If Earth didn’t wobble, the stars would appear to be in the same place they were hundreds of years earlier. A lunar eclipse allowed him to see the stars and know exactly where the Sun was for comparison – directly opposite the Moon. Greek astronomer Hipparchus made this discovery by comparing the position of stars relative to the Sun during a lunar eclipse to those recorded hundreds of years earlier. Earth completes one wobble, or precession cycle, over the course of 26,000 years. He realized that only if Earth were a spheroid would its shadows be round – a revelation that he and others had many centuries before the first ships sailed around the world.Įarth wobbles on its axis like a spinning top that’s about to fall over, a phenomenon called precession. In ancient Greece, Aristotle noted that the shadows on the Moon during lunar eclipses were round, regardless of where an observer saw them. Lunar eclipses have long played an important role in understanding Earth and its motions in space. Put more poetically, it’s the light from countless sunrises and sunsets.Explore our collection of standards-aligned lessons for grades 1-12. During the total phase, the only light falling on the moon’s near side will come from the reddish light refracted by Earth’s atmosphere. Tuesday, with totality lasting from 2:17 to 3:42 a.m.

The partial phase of tonight’s eclipse begins at 1:44 a.m. Totality occurs when the moon passes directly through the darkest part of Earth’s shadow, known as the umbra. During a partial eclipse, only a portion of the moon goes dark. Lunar eclipses occur when Earth and the moon are positioned such that our planet blocks out the sunlight falling on the lunar surface. And even if it’s cloudy, you can hedge your bets by tuning in NASA’s live stream of the event.

If you’re on the West Coast, watching tonight’s total lunar eclipse will require a willingness to stay awake in the middle of the night - plus a lucky break on the weather.īut maybe it’s worth taking a chance: The next opportunity to take in the sight of a blood-red, eclipsed moon won’t come until 2025. This graphic shows the phases of the Nov.
