ECLIPSES
They have been thought of as harbingers of evil as well as a sign of the divine.
Eclipses—one of the most stunning celestial events that can be witnessed on Earth—have shaped the course of history and thought since humans first turned their eyes to the sky.
THE GREAT NORTH AMERICAN
TOTAL SOLAR ECLIPSE

Types of Solar Eclipses
PARTIAL SOLAR ECLIPSE
The Moon does not pass directly in front of the Sun.
ANNULAR SOLAR ECLIPSE
The Moon is too small to obscure the Sun completely.
TOTAL SOLAR ECLIPSE
The Moon completely obscures the Sun.
THE NEXT TOTAL LUNAR ECLIPSE:

from eclipse.gsfc.nasa.gov: Fred Espenak
The next total lunar eclipse will be on May 26, 2021. It will be visible across the mainland United States in the early morning as the Moon sets. The duration of the total phase is 15 minutes. The previous total lunar eclipse occurred on January 21, 2019.
MASK OF THE SUN
What do Virginia Woolf, the rotation of hurricanes, Babylonian kings and Einstein's Theory of General Relativity have in common? Eclipses.
Always spectacular and, today, precisely predictable, eclipses have allowed us to know when the first Olympic games were played and, long before the first space probe was launched, that the Moon was covered by a layer of dust.
Eclipses are mentioned in Homer's Iliad and Odyssey and eight times in the Bible. The ancient Romans thought it was a bad idea to have sexual intercourse during an eclipse, while people in the South Pacific encouraged it.
Mask of the Sun explains why and how eclipses occur—and why the number 177 is important in eclipse prediction—and gives insight into the forthcoming total solar eclipse of 2017 that will be visible across the United States.
