The two main categories of eclipses are solar eclipses and lunar eclipses; each has several subcategories. Eclipses occur often, but are commonly visible in only one part of the world, or aren't visible to other countries. The eclipses only go so far around the earth that's why many can't see them.
Solar eclipses happen when the Moon moves between Sun and Earth, blocking the Sun's rays and casting a shadow on Earth. Check out our animations and map of the annular and total solar eclipse in 2017. Solar eclipses are usually bright.
Should pet owners outfit their furry friends with protective eyewear during the eclipse? Some pets don't even bother to look at the sun. As the sky darkens farm animals such as cattle may think nighttime is approaching and thus may head back to the barn. Birds may also be fooled into thinking it's nightfall, and may start "making lots of noise to show they're getting ready to go to bed."
A total solar eclipse happens somewhere on Earth once every year or two. What is an eclipse? Learn more about how solar eclipses happen, the four types of Eclipses are Hybrid, Partial, Total, and Annular. They each have there own purpose for coming or showing up in the sky.
