For once, this means that the weather forecast is good. It promises a nice weather until Friday night – so you'll be able to see what's spectacular in the sky. It is a total lunar eclipse, in the vicinity of which there is a brightly luminous Mars. More the planet Saturn. Extraordinary this lunar eclipse is because it will take longer than an hour and 43 minutes in this still young age. However – it's the downer – when it's dark, it's already booming.
A lunar eclipse occurs when the moon wanders through the shadow of the earth, so that the earth enters the sun and the moon. This can only happen when the sun is directly opposite to the moon, ie to the full moon. The fact that each full moon does not cause a lunar eclipse is due to the fact that the lunar orbit – its orbit – is a little twisted. Thus, only a maximum of three total lunar eclipses can be observed per year. The moon becomes reddish. The air envelope of the Earth scatters sunlight and filter. The red part (long wave) of the light passes through the atmosphere better, the blue is more strongly diffused on the molecules of the air.
The Moon – An Explanation from A to Z
He has always engaged people. But what do we know about the moon that is obscured by the Earth's shadow tonight?
Apollo 11 : On July 20, 1969, the first man stepped on the lunar surface. The landing is preceded by an ambitious race between the United States and the Soviet Union. At 4:35 pm Central European time, Neil Armstrong opens the hatch and goes down. Edwin Aldrin follows him.
Bahn : Since Apollo astronauts installed laser reflectors on the moon, the distance to the Earth can be measured accurately. It shows: The moon is moving away from the earth, in a hundred years of 38 meters. Today, the large half axis of the ellipse of the lunar orbit measures 384400 kilometers.
Genesis : 4.5 billion years ago, the moon formed from a cloud of debris.
Spots : The biggest riddles for humans have always been the spots that can be seen at the naked eye. Is it a face? Or a living thing? In fact, the high plateaus strewn with Terrae craters (Crater) and the dark Maria (seas) are washing-off grounds – and all dry.
Tides : The gravitational force of the Moon is responsible for the appearance of tides, tides. The moon produces two flood plains, one on the side facing the moon and one on the back. The two plains of flood brake the earth in rotation
Inner Life : The volume of the moon is one fiftieth of the volume of the Earth, while the mass of the Moon is only one and eighty-one. This means that the moon is lighter than the earth, probably because it does not have an iron-nickel core as big as the earth.
Crater : In the first billion years after its creation, the moon was subjected to a violent cosmic bombardment. This left deep marks on its surface.
Mood : In the past, sight prevailed that the moon influenced time and the spirit. The word "mood" comes from the Latin "luna" for moon. The "crazy" English means crazy.
Retour : Because the earth has a strong attraction, the moon always turns towards us on the same side. What does the back look like? Response from two Soviet space probes: There are less dark plains.
Temperature : Because neither the atmosphere nor the water absorb heat radiation, the moon cools to minus 130 degrees Celsius overnight and heats up to # At 120 degrees Celsius during the day.
Origin : There are several theories about the origin of the moon. Since 1975, the explanation is favored that the moon is a part of the land separated from a collision with a body of about the size of Mars.
Cycle : On Earth, the moon is illuminated in different ways. The extremes form the new moon and the full moon, the whole cycle lasts 27.3 days.
