During a total or annular solar eclipse, people outside the area covered by the Moon’s inner shadow see a partial solar eclipse. Only a part of the Sun will appear to be covered, giving it a crescent shape. Partial Solar Eclipse Partial Solar EclipseĪ partial solar eclipse happens when the Moon passes between the Sun and Earth but the Sun, Moon, and Earth are not perfectly lined up. As a result, the Moon appears as a dark disk on top of a larger, bright disk, creating what looks like a ring around the Moon. Because the Moon is farther away from Earth, it appears smaller than the Sun and does not completely cover the Sun. will be on April 8, 2024.Īnnular Solar Eclipse Annular Solar EclipseĪn annular solar eclipse happens when the Moon passes between the Sun and Earth, but when it is at or near its farthest point from Earth. A total solar eclipse is the only type of solar eclipse where viewers can momentarily remove their eclipse glasses (which are not the same as regular sunglasses) for the brief period of time when the Moon is completely blocking the Sun. Weather permitting, people in the path of a total solar eclipse can see the Sun’s corona, the outer atmosphere, which is otherwise usually obscured by the bright face of the Sun. The sky will darken, as if it were dawn or dusk. People located in the center of the Moon’s shadow when it hits Earth will experience a total eclipse.

A hybrid eclipse appears as either a total or an annular eclipse (the left and middle images), depending on the observer’s location. Blue light has a shorter wavelength and is scattered more easily by particles in Earth’s atmosphere than red light, which has a longer wavelength.From left to right, these images show a total solar eclipse, annular solar eclipse, and partial solar eclipse. Light travels in waves, and different colors of light have different physical properties. The same phenomenon that makes our sky blue and our sunsets red causes the Moon to turn red during a lunar eclipse. Why does the Moon turn red during a lunar eclipse? NASA provides a monthly skywatching tips series that will highlight additional targets to focus on in between monitoring the eclipse. The Moon will be in the constellation Aries. The whole Moon is in Earth’s penumbra, but again, the dimming is subtle. It will look as if a bite is being taken out of the opposite side of the lunar disk as before. If you want to take a photo, use a camera on a tripod with exposures of at least several seconds.Īs the Moon exits Earth’s umbra, the red color fades. Try binoculars or a telescope for a better view. The entire Moon is now in the Earth’s umbra. The part of the Moon inside the umbra will appear very dark. To the naked eye, as the Moon moves into the umbra, it looks like a bite is being taken out of the lunar disk. The Moon begins to enter Earth’s umbra and the partial eclipse begins. The Moon begins to dim, but the effect is quite subtle. The Moon enters the Earth’s penumbra, the outer part of the shadow. You can also visit NASA’s Dial-a-Moon for a visualization of the eclipse. ![]() Join in online: Live Stream the November 8 Lunar Eclipse Credit: NASA Goddard Space Flight Center/Scientific Visualization Studio What if it’s cloudy or I’m not in the viewing region? The map is centered on 168★7'W, the sublunar longitude at mid-eclipse. Contours mark the edge of the visibility region at eclipse contact times. Viewers in Alaska and Hawaii will have the opportunity to see every stage of the eclipse.Ī map showing where the Novemlunar eclipse is visible. The eclipse is also visible in Asia, Australia, and New Zealand. In Puerto Rico, the Moon sets just after totality begins. Totality ― the stage of the eclipse where the Moon is entirely in Earth’s shadow ― will be visible across North and Central America and in Ecuador, Colombia, and western portions of Venezuela and Peru. A dark environment away from bright lights makes for the best viewing conditions. You don’t need any special equipment to observe a lunar eclipse, although binoculars or a telescope will enhance the view and the red color. Lunar eclipses are sometimes called “Blood Moons” because of this phenomenon. When the Moon is within the umbra, it will turn a reddish hue. In a total lunar eclipse, the entire Moon falls within the darkest part of Earth’s shadow, called the umbra. The last total lunar eclipse for three years occurs on November 8, 2022, with the next occurring on Mathough we will continue to see partial and penumbral lunar eclipses during that time.Ī lunar eclipse occurs when the Sun, Earth, and Moon align so that the Moon passes into Earth’s shadow. What’s special about November’s lunar eclipse?
