Photo gallery: Lunar eclipse July 2018 in Iran

A total lunar eclipse took place on 27 July 2018: The Moon has passed through the centre of the Earth’s shadow.

This eclipse was the longest total lunar eclipse in the 21st century, since it occurred near apogee (the Moon’s orbit point farthest from the Earth). It lasted approximately 103 minutes. The moon remained at least partially in Earth’s shadow for a total of four hours. The eclipse occurred simultaneously with the perihelic opposition of Mars (Mars is closest to the Sun and particularly close to Earth), a coincidence that happens once every 25,000 years.

A lunar eclipse occurs when the Moon passes within Earth’s umbra (shadow). As the eclipse begins, Earth’s shadow first darkens the Moon slightly. Then, the Earth’s shadow begins to “cover” part of the Moon, turning it a dark red-brown color (typically – the color can vary based on atmospheric conditions). The Moon appears to be reddish because of Rayleigh scattering (the same effect that causes sunsets to appear reddish) and the refraction of that light by Earth’s atmosphere into its umbra. The Moon’s brightness is exaggerated within the umbral shadow.
