The ancient Maya may have used a y-shaped stick to help them look at the sky’s objects. They May have used mirrors (made from stone they’d polished) to watch eclipses .
For many ancient peoples , solar eclipses were a reason to be afraid — very afraid . Ancient peoples depended heavily on the seasonal changes reflected in the annual movements of the sun, Krupp told Live Science.

The total solar eclipse , which is the last eclipse of 2020 , will be visible to observers across a narrow swath of the South Pacific, Chile, Argentina and the southern Atlantic Ocean, while a partial eclipse will be visible from a wider region in the Pacific, southern South America and Antarctica.
Maya astronomer -priests looked to the heavens for guidance. They used observatories, shadow-casting devices, and observations of the horizon to trace the complex motions of the sun, the stars and planets in order to observe, calculate and record this information in their chronicles, or “codices”.
The Mayans were careful observers of the sun , able to accurately predict eclipses and celestial cycles. Keeping track of the seasons for agricultural purposes was so important that buildings and settlements were designed to help follow the sun’s yearly cycles.
There is no danger to the eye in looking directly at a total solar eclipse . However; looking directly at the smallest part of a partial eclipse , including any annular eclipse , is very dangerous and can result in retinal damage.
During a total solar eclipse so much of the sun is covered that a person may be tempted to stare at it directly. It is possible to suffer serious and permanent eye damage by looking at any type of solar eclipse and there is no treatment. Children are especially at risk due to more light reaching the retina than adults.
As in ancient China on other early cultures, the Vikingsbelieved the sun was being eaten during an eclipse . Their legend involves two wolves, Hati and Skoll, who sought to eat celestial bodies. Skoll sought out the moon, and Hati the sun. When one caught up to its prey, the lights would go out.
Total solar eclipses produce harmful rays that can cause blindness. During a total solar eclipse when the disk of the moon fully covers the sun, the brilliant corona emits only electromagnetic radiation, though sometimes with a greenish hue. Scientists have studied this radiation for centuries.
Solar eclipses are fairly numerous, about 2 to 4 per year , but the area on the ground covered by totality is only about 50 miles wide. In any given location on Earth, a total eclipse happens only once every hundred years or so, though for selected locations they can occur as little as a few years apart.
The Different Types of Eclipses A solar eclipse is when the sun is covered by the Moon. There are four types of solar eclipses . Partial eclipse . In a partial eclipse , the Moon crosses the path of the sun, but does not completely block it out. Annular eclipse . Total Eclipse . Hybrid Eclipse .
This blood moon occurs during a total lunar eclipse. During a total lunar eclipse, Earth lines up between the Moon and the Sun. This hides the Moon from the sunlight. The name ” blood moon ” is also sometimes used for a Moon that appears reddish because of dust, smoke or haze in the sky.
Even viewing it through a telescope is risky. You can watch it on television,” he says. Unless specifically designed for the purpose, no filter is safe to use with any device, be they telescopes or binoculars. Ready-made eclipse viewers are available which may be used, he adds.
During the brief period of totality, when the sun is completely covered, the beautiful corona — the tenuous outer atmosphere of the sun — is revealed. Totality may last as long as 7 minutes 31 seconds , though most total eclipses are usually much shorter.
