July will see the longest total lunar eclipse of the 21st century. But that’s not all: Mars will then come extremely close to Earth.
It is a sky spectacle that happens very rarely: A total lunar eclipse – which lasts longer than one and a half hours – and besides, the red planet Mars is as close to the Earth as rarely. In good weather you can look forward to a special spectacle: the so-called blood moon.
July 27th is the day. But first things first!
At 8.24 p.m. the moon enters the umbra of the Earth, then the Earth is between the Moon and Sun. The shadow of the Earth moves over the Moon: Firs,t the shadow covers only the edge, later the whole Moon lies in the shadow – then there is a total lunar eclipse.
From 9.30 to 11.14 pm the moon is completely in the shadow of the Earth – for one hour and 44 minutes, there is a total lunar eclipse. This lunar eclipse duration is only surpassed again on 9 June 2123 – by two minutes.
The lunar eclipse will stretch across most of Europe and Asia, Australia, Africa and part of South America. North and central Americans won’t be able to see the eclipse.
The “Blood Moon” glows dark red
In the phase of total darkness, the Moon appears weak dark red shining – because not all the light of the Sun is shielded from the Earth. Experts speak of a long-wave light that bends around the Earth and makes the moon appear dark red. That is why this phenomenon is also called the blood moon.
