A total solar eclipse-the only one of this year- will happen on December 4, Nevertheless not will be visible from Hellas.
The “path” of the eclipse will be fully visible only for a moment from Antarctica and the South Atlantic Ocean, so the penguins will probably see it in its entirety, while it will be partially visible from South Africa and southern Oceania.
This completes the eclipses of 2021, as it was preceded by a total lunar on May 26, an annular solar on June 10 and a partial lunar on November 19.
In 2022 there will be a partial solar on April 30, a total lunar on May 15-16, a second partial solar on October 25 (visible from Greece), and a total lunar on November 7-8. The next total solar will occur on April 20, 2023.
Solar eclipses occur when the Moon intervenes between the Earth and the Sun, completely covering the solar disk and thus revealing the outer atmosphere of our star, the so-called crown. The diameter of the Sun is about 400 times larger than that of the Moon, but the latter also happens to be almost 400 times closer to the Earth than the Sun, so it can cover it from the eyes of an Earth observer.
The US space agency (NASA) will broadcast the Antarctic eclipse both on its YouTube channel and at nasa.gov/live, starting at 08:30 Greek time on Saturday and ending at 10:37 am.
