It’s derived from the Latin eclipsis or Greek ekleipsis. The word “eclipse” also has a pretty foreboding history. This happens more often than you might think–since every solar and lunar eclipse is actually a syzygy. The other way is for something to pass between the obscured object and the viewer.įun trivia fact, if three things get themselves in a line it’s called a syzygy. The first is passing through the shadow of something else. An eclipse, in the context of astronomy, just means an object has been obscured by one of two means. Eclipses are a thing outside the scope of just the Sun and Moon, though. You’re probably kind of familiar with what an eclipse is, at least in the context of both the solar and lunar ones. What you might not have heard is that the Blood Moon is actually a lunar eclipse, which might have you thinking: what’s the difference between a solar and lunar eclipse? Also, what is a Blood Moon? Okay, what’s an eclipse, though? Which sounds… pretty intimidating, but at least it’s not going to be turning you into an eldritch abomination or something. You also may have seen headlines about a Blood Moon, which did happen halfway through May 2022. Because Earth is the third planet from the Sun, we are able to observe transits of both Mercury and Venus.If you’ve been looking at the moon recently, you might notice the moon looks a little different. For example, when Mercury passes between the Sun and the Earth, this is called a transit of Mercury. A transit occurs when one celestial body passes between a larger celestial body and a third celestial body.There is also a phenomenon called a transit, which is similar to an eclipse, though not quite as visually stunning: 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.During a total solar eclipse, the Sun is completely obscured by the Moon, resulting in a brief period of awe-inspiring darkness.During a total lunar eclipse, the Moon is completely obscured by the dark center of Earth’s shadow (called the umbra), giving the Moon a dark, reddish hue.A total eclipse (of either the Moon or the Sun) occurs when the Moon or Sun is entirely blocked out.There are a few different ways for lunar and solar eclipses to happen: Lunar eclipses are technically visible from the entire night side of Earth, but during a penumbral eclipse, the dimming of the Moon’s illumination is slight. A lunar eclipse occurs when the full Moon enters the shadow of Earth, which cuts off all or part of the sunlight reflected off the Moon.A solar eclipse occurs when the Moon passes directly in front of the Sun, partially or entirely blocking out its light. Solar eclipses are visible only in certain areas and require eye protection to be viewed safely.The two types of eclipses that we witness here on Earth are solar eclipses and lunar eclipses: The Moon will enter the penumbra at 3:01 A.M. This eclipse is visible from North America, although the Moon will be setting during the eclipse for observers in eastern regions. November 8, 2022: Total Eclipse of the Moon. (The partial solar eclipse is visible from Greenland, Iceland, Europe, northeastern Africa, the Middle East, western Asia, India, and western China.) This eclipse is not visible from North America. October 25, 2022: Partial Eclipse of the Sun. The Moon will enter the penumbra at 9:31 P.M. This eclipse is visible from North America, except in northwestern regions. (The partial solar eclipse is visible from the southeastern Pacific Ocean, the Antarctic Peninsula, and southern South America.) April 30, 2022: Partial Eclipse of the Sun.
