This website relays shocking news discovered by astronomers peicing together the past. The moon is getting further away and the earth is slowing down. These two major events are actually linked. When the moon makes water bulges, or tides, the earth drags those water bulges faster, resulting in a tug on the moon. This tug forces the moon higher into orbit and consequently, the earth loses a tiny amount of energy and slows down. This movement only happens at a rate of 3.8 centimeters/year. This is where this ties into the solar eclipse, because eventually the moon will be so far away from earth, it will interfere with perspective and the moon will not appear to cover the surface of the sun. This means a solar eclipse will become obsolete! (Of course, it will only take 620 million years to happen!)
This article explains the consequences of viewing a solar eclipse, as well as the condition called solar retinopathy, when sunlight floods the retina, releasing a damaging chemical. The article also tells of early astronomers, discovering the dangers of viewing a solar eclipse without proper eye protection. Early astronomers even recorded having poor sight for up to an hour while observing sun spots for a short period of time. The condition, solar retinopathy, is much more common during an eclipse, because viewers are drawn to the eclipse, and view it for a much longer time period then one might normally glance at the sun.
This video explains that a solar eclipse is a rare event when the moon covers the sun, blocking the light, making it appear as though it is night. The video also explains in a unique way, via a model, that shows why we see a solar eclipse the way that we do, because of our perspective from earth. The sun appears the same size as the moon, but it isn't, the sun is just further away. If it were not for a slight tilt of the moon, earth would experience a solar eclipse roughly each month!
This article explains that solar eclipses have actually been used in a number of movies. There is even a silent film by film artist George Méliès, called The Eclipse. Typically, film makers would use an eclipse to change a mood. In fact, some film makers would wait years, just to film a scene featuring a solar eclipse.
