Solar eclipse 2020: when and where to see the annular eclipse

This weekend, stargazers in the eastern hemisphere will receive an annular solar eclipse on the heels of the summer solstice. This type of eclipse is characterized by its impressive ” ring of fire “, as it is not a total eclipse and the edges of the sun can still be seen around the moon.

“Ring eclipses are similar to total eclipses in that the moon, Earth and the sun are aligned so that the moon moves directly in front of the Sun as seen from Earth,” said Alex Young, associate director of science at the Division of Heliophysics Sciences, NASA’s Goddard Space Flight Center .

“But a total eclipse does not occur, that is, the moon does not completely block the visible disk of the sun because the moon is further away, and therefore its apparent size in the sky is [slightly] smaller than that of the sun. This means that a tiny annular ring in the solar disk is visible around the moon. ” Young said that solar eclipses occur approximately two weeks before or after a lunar eclipse. There was a lunar eclipse on June 5 and the next one occurs on July 5.
