Mercury’s proximity to the Sun makes it difficult to observe (unlike other planets). Because Earth is the third planet from the Sun, we are able to observe the transits of both Mercury and Venus. A transit occurs when one celestial body passes between a larger celestial body and a third celestial body. For example, when Mercury passes between the Sun and the Earth, this is called a transit of Mercury. There is also a phenomenon called a transit, which is similar to an eclipse, though not quite as visually stunning. You can read more about the types of solar eclipses here. The effect is so slight that a penumbral eclipse can be hard to recognize unless you know to look for it! Penumbral eclipses occur when the Moon enters only the faint outer edge of Earth’s shadow (called the penumbra), which causes the Moon to appear slightly darker than usual. A penumbral eclipse is a type of lunar eclipse.This results in a very bright ring of light called an annulus. Annular eclipses are similar to total solar eclipses (where the Sun is completely obscured by the Moon), but in an annular eclipse, the Moon’s apparent size is smaller than the Sun’s, meaning that the Sun is not completely obscured. An annular eclipse is a type of solar eclipse.A partial eclipse (of either the Moon or the Sun) occurs when only part of the Moon or Sun is obscured.
The next total solar eclipse to visit North America will be on April 8, 2024. Though lunar eclipses and solar eclipses happen with the same frequency (about 4 to 7 times a year, in total), it’s rare to see a solar eclipse since they are only visible from a small area of Earth each time. Solar eclipses are visible only in certain areas and require eye protection to be viewed safely. If the alignment is a little off-center, the Moon may just partially block our view of the Sun. If the alignment is perfect, the Moon completely blocks our view of the Sun, casting its dark shadow on Earth. The Moon, Earth, and Sun are aligned with the Moon stuck in the middle. What is a Solar Eclipse?ĭuring a solar eclipse, the Moon blocks the Sun from view. The eclipse is technically visible from the entire night side of Earth, but during a penumbral eclipse, the dimming of the Moon’s illumination is slight.

But only longer wavelengths make it these are the red and orange colors.Ī lunar eclipse only happens on the full Moon. This is because some of the light from the Sun makes it through Earth’s atmosphere. Sometimes, the Moon appears reddish-orange during an eclipse. Instead, Earth’s shadow is cast upon the Moon’s surface. This happens because the Earth is positioned exactly between the Moon and the Sun, blocking much of the sunlight from reaching the Moon’s surface. What is a Lunar Eclipse?ĭuring a lunar eclipse, the Moon appears dark or dimmed. The annular phase is visible in a narrow path that runs through Oregon, Nevada, Utah, Arizona, New Mexico, and Texas. This eclipse is at least partially visible from most of North America. October 14, 2023: Annular Eclipse of the Sun. (It is visible only from the southern Indian Ocean, parts of Antarctica, most of Australasia, Indonesia, the Philippines, most of Oceania, and the western Pacific Ocean.) This hybrid eclipse, which is seen as annular or total depending on view location along its path, is not visible from North America. Solar Eclipses 2023Īpril 19–20, 2023: Annular Total Eclipse of the Sun. The Moon will enter the penumbra at 2:00 P.M.
The Moon will rise during the eclipse, and observers will only see a penumbral eclipse. This eclipse is visible from northeastern North America. October 28, 2023: Partial Eclipse of the Moon. June is the Time for Venus! At Its Brightest in 8 Years.
