Reuters, October 13, Washington On Saturday, millions of people in the Americas will have the opportunity to view a solar eclipse, 

 in which the moon will, weather allowing, pass in front of the sun.

The eclipse is expected to be visible in a path that passes through sections of the United States, Mexico, and a number of Central and South American nations.

Here is a description of the sort of solar eclipse that will take place and the locations from which it will be seen.

A solar eclipse occurs when the moon travels between Earth and the sun, obstructing the view of the sun's face along a narrow swath of Earth as it passes. 

The type of eclipse that will take place on Saturday is known as a "annular solar eclipse." 

According to experts, it is dangerous to look straight at the bright sun without using specific eye protection made for solar viewing,

 which increases the risk of eye injury. An annular solar eclipse never completely blocks out the sun, thus looking directly at it without such eye protection is never safe.

The moon experiences a lunar eclipse when Earth is directly between the moon and the sun. The effect is that the moon appears dull and occasionally reddish from Earth. This is how it differs from lunar eclipse
