How long does a total solar eclipse last?
seven minutes and 32 secondsIt can take several hours for the Moon to pass in front of the Sun, but the moment of total eclipse (called totality) lasts only minutes - up to a maximum of seven minutes and 32 seconds. The period of totality varies because the apparent sizes of the Moon and Sun change depending on their distance from Earth.

Can an eclipse last 3 hours?
A total lunar eclipse can last up to nearly 2 hours, while a total solar eclipse lasts only up to a few minutes at any given place, because the Moon's shadow is smaller. Also unlike solar eclipses, lunar eclipses are safe to view without any eye protection or special precautions.

The dark areas symbolize night and twilight. Note: The animation follows the eclipse shadow from west to east, its point of view moving around the planet at a greater speed than Earth's rotation. If you don't take into account this rapid change of perspective, it may look like Earth is spinning in the wrong direction.

When an eclipse begins, at 1st contact, it appears as if the Moon is taking a bite out of the Sun.
How long does a solar eclipse last?
Solar eclipses occur in cycles. The Saros cycle, one of the most studied eclipse cycles, lasts for 18 years. Two solar eclipses separated by a Saros cycle have similar features—they occur at the same lunar node, with the Moon roughly at the same distance from the Earth.

What is the only requirement for a total solar eclipse?
The only requirement for a total solar eclipse is that the angular size of the sun has to match the angular size of some other object that passes in front of it. When the disk of the object is smaller than the sun, this is called a transit. It is also called an eclipse when the disk of the object is much larger than the sun, but in general this would not allow the corona to be viewed, which is how we define total solar eclipses viewed from Earth. When humans were rooted to the surface of Earth, this was only the case for the moon as the eclipsing object. But there are many known moons and asteroids across our solar system, and from a suitable vantage point near any of them, we can find a distance where again the angular size of the object matches that of the sun to form a total solar eclipse. There are so many different vantage points to choose from that each case has to be specified. For example, eclipses need not be observed from the surfaces of a planet. In fact, Venus and the outer planets have inaccessible surfaces. Instead, we might consider standing on the surface of a planetary moon and waiting for another moon to pass in front of the sun. Given the myriad of planetary moon orbits, finding those instances where the angular sizes match is a significant computational challenge. Jupiter frequently passes across the sun as viewed from its moons, but its diameter is huge compared to the sun. There are 5 satellites capable of completely occulting the Sun: Amalthea, Io, Europa, Ganymede and Callisto. All of the others are too small or too distant to be able to completely occult the Sun, so can only transit the Sun.
How to photograph eclipses?
If you ONLY take a photo at the moment of totality, you will not need this filter, and will be rewarded by being able to photograph the faint corona, which will not be visible if you have the filter in place. Most digital cameras with telephoto lenses of 100 mm or larger will show a disk for the eclipse that will show some detail . As a trial, photograph the full moon at night. It will be the same diameter as the total eclipse, so you can practice on the moon first to get the right telephoto lens combination. There are many places on the internet where you can get detailed information such as Mr. Eclipse http://www.mreclipse.com/SEphoto/SEphoto.html
Why do solar eclipses occur?
Eclipses occur due to the special coincidence of the moon and the Sun being the same angular size. The Sun is 400 times wider than the moon, but it is also 400 times farther away, so they coincidentally appear to be the same size in our sky. This is what allows us the phenomenal beauty of the total solar eclipse.
Why is it possible for the Sun to be in full eclipse?
Because the geometry required for a total solar eclipse has nothing to do with local noon. It has to do with when the lunar shadow sweeps across your location during the time when the Sun is above the horizon. Even so, it is certainly possible for the Sun to be in full eclipse before it rises at your particular location.
When will the next solar eclipse be in 2024?
After that, the next one visible from the Lower-48 will be on April 8, 2024 which will track northeast from Texas to Maine and cross the path of the 2017 eclipse near Carbondale, Illinois. Since 1503, there have been 15 total solar eclipse paths that have crossed the path of the August 2017 eclipse.
Why is the moon's limb not smooth?
The moon’s limb is not perfectly smooth because of the mountain ranges and canyons that pepper the moon’s circumference as viewed from Earth. Shortly before the moon fully blocks the disk of the sun during a total solar eclipse, flashes of light can often be seen around the circumference of the moon’s blackened disk.
What happens if you stare at the sun for too long?
Solar retinopathy is a result of too much ultraviolet light flooding the retina. In extreme cases this can cause blindness, but is so painful that it is rare for someone to be able to stare at the sun for that long. Typically, eye damage from staring at the sun results in blurred vision, dark or yellow spots, pain in bright light or loss of vision in the center of the eye (the fovea). Permanent damage to the retina has been shown to occur in ~100 seconds, but the exact time before damage occurs will vary with the intensity of the sun on a particular day and with how much the viewer's pupil is dilated from decongestants and other drugs they may be taking. Even when 99% of the Sun's surface (the photosphere) is obscured during the partial phases of a solar eclipse, the remaining crescent Sun is still intense enough to cause a retinal burn. Note, there are no pain receptors in the retina so your retina can be damaged even before you realize it, and by then it is too late to save your vision!
