The moon is partially covered by the earth's shadow and shrouded in orange light over beautiful coastal scenery.

Partial Lunar Eclipse over southern Portugal

image

Légende : The image shows a partial lunar eclipse from the 16th of July 2019, taken in southern Portugal. A lunar eclipse happens at full moon so without the eclipse we would see the full lunar disk. Earth’s curved shadow is clearly visible on the left side of the lunar disk. The remaining surface of the Moon is dipped into a deep orange color due. This is because at a lunar eclipse the Earth is positioned between the Moon and the Sun. While the solid part of the Earth creates the shadow we see on the left side of the Moon, sunlight also shines through Earth’s atmosphere. This scatters blue sunlight allowing most red sunlight through, the same process which turns the evening sun into a beautiful and colorful sunset.

Lunar rainbow and lunar Brocken spectre, by Kouji Ohnishi, Japan

Lunar rainbow and lunar Brocken spectre, by Kouji Ohnishi, Japan

image
Créé pour l'OAE

Légende : Third place in the 2021 IAU OAE Astrophotography Contest, category Sun/Moon haloes. This stunning photograph of the lunar rainbow and the lunar Brocken Spectre amidst the night sky was captured from Mount Tsubakuro located in Japan’s Hida Mountains in Nagano. Both these atmospheric occurrences are due to the moon’s light being reflected and refracted from water droplets. A lunar rainbow or a moonbow is a rare phenomenon that occurs with the right settings of a bright full moon which is less than 42° high, rain on the opposite side of the moon and a dark night sky. The Brocken Spectre is named after the highest peak of the Harz mountain range in Germany, where it was first recorded. Here it is seen from the summit as a magnified shadow of the observer cast onto the cloud surrounded by a glory consisting of concentric circles centered at the point directly opposite the bright moon in the background.

The eclipsed Moon sets near the Rochetta di Prendera, Dolomiti Unesco, by Alessandra Masi, Italy

Créé pour l'OAE

Légende : First place in the 2021 IAU OAE Astrophotography Contest, category Total lunar eclipse. A lunar eclipse occurs when the full moon moves into the Earth`s shadow. This is the case when the Sun, Earth and Moon are exactly or very closely aligned. The reddish light reflected from the lunar surface is caused by sunlight that has been refracted on its way through Earth´s atmosphere in the direction of the Moon. It appears reddish because of the Rayleigh scattering of bluer light. The round shape of the Earth's shadow visible on the lunar surface was a proof for Aristotle that the Earth must be a sphere. This photo shows the eclipsed Moon that sets near the Rochetta di Prendera, Dolomiti Unesco, Italy, on 21 January 2019.
