It was an event of the century Friday night. There was nothing less to see than the "Bloodmoon," as popularly known as the earthly moon plunged into a coppery red light. And not too close: for a total of 103 minutes, the Moon plunged into the shadow of the Earth – the longest total lunar eclipse of the 21st century.
For astronomical societies scattered throughout the country, it was an opportunity for once again to secure. In the evening, at the planetarium of the Verkehrshaus Luzern, many visitors followed the simulation of a lunar eclipse every half hour. After that, a live broadcast was scheduled in the Verkehrshaus cinema
At the Lucerne wharf, the atmosphere was relaxed before the rising of the moon, as Marc Eichenberger, president of the Lucerne Astronomical Society, described the Atmosphere at the Keystone-SDA agency. Three telescopes with lenses have already been put in place. It suits everything: the event falls on a Friday night, it is hot, the view is beautiful.
Time was not perfect in Bern
More and more people were arriving at the Big Sternschanze in Bern before moonrise, according to the SDA's key photographer on the spot. Several tripods of photographers are already waiting. However, the weather was not optimal, a little foggy and slightly cloudy along the Alps.
The phenomenon "blood moon" is caused by the scattered light of the sun. Above all, the red parts of the light are broken by the Earth's atmosphere into the cone of shadow.
Also Mars was visible
Coincidentally, he wanted, that very close to the full moon the planet Mars as close to the earth is. The red planet could be seen at the width of one hand below the darkened moon disc and even surpbaded even Jupiter in brilliant.
The only uncertain factor was time. The clouds have hardly spoiled the observers. The next total lunar eclipse of the same length as July 27 is expected again for the year 2123.
Facts of the Galactic Moon:
- Water: The Dark Parts of the Moon were once filled with lava that has hardened over time.
- Distance: The Moon is 384 kilometers from us equals 60 times the Zurich-New York route.
- Animal: Wolves howl at each moon. Although the animals are nocturnal, they scream especially at night, but regardless of the phases of the moon.
- Men in the Moon: Near Neil Armstrong were eleven other astronauts on the moon. The last in December 1972.
- Time: One day on the Moon takes 29 days – it takes as long to turn around its own axis.
- Plural: The Earth has only one Moon, which has Jupiter 61.
- Brilliant: On the Moon is a mirror that was used to measure the speed of light.
- View: We still see the same side of the moon from Earth because it is in a bounded rotation with the Earth.
- Bye: The Moon drifts four centimeters further from the Earth each year.
- Light: Would we land on the moon? Libra, she only showed one-sixth of the weight of the one on Earth.
- Action: There are Moonquakes! The reason is the attraction that the Earth exerts on the opposite side of the moon.
What is a lunar eclipse?
A total lunar eclipse occurs when the moon wanders through the shadow of the Earth. It happens when the earth is between him and the sun. On its side opposite to the sun, the earth casts a base base shadow. Around this, there is a penumbral shadow that continually expands as the distance of the earth increases.
The Moon turns around the Earth once every 30 days or so. Its eccentric orbit is slightly inclined relative to the orbit on which the earth pulls around the sun. For most orbits, the moon pbades above or below the earth's shadow. You can see it as a full moon right now.
There is a lunar eclipse when the moon reaches the shadow of the Earth. This happens at a point where the two orbits intersect. The lunar eclipse can be seen wherever the moon is above the horizon right now. From central Europe, lunar eclipses can be observed once or twice a year.
