Look above all, because there is something special to see: a complete lunar eclipse. The moon is not invisible, but bright red. How is?
A lunar eclipse or eclipse occurs when the earth is placed exactly between the sun and the moon. "The direct sunlight on the moon is then completely stopped," explains Marlies van de Weijgaert. She works at the astronomy program of the University of Groningen
Part of the sunlight reaches the moon, she is deflected by the atmosphere of the earth towards the moon. "But the blue and green colors are curving toward the space, the red rays of light are diverted to the moon, and provide the blood-red color, even if it takes a moment before it is full power."
By 9:30 pm the earth is completely for the moon, but it is not yet dark enough. From 22:30, the lunar eclipse is at its best, says Van de Weijgaert. "Then he is also higher, which makes him more visible."
Astronomer Carl Koppeschaar explains that the planet Mars can also be seen tonight.
