In natural phenomena, Japan, the most famous of the eclipse can be classified as out. Even today, many religious denominations also gives the moon the color of food. For example, in India, some of the tribes that eclipse is a dragon swallowed the moon. Fortunately, there is a hero cut off the dragon's head. So the moon was soon reproduced. In our country there Tengu eat moon legend. Regardless of whether people now believe that these legends, it is not important, but it reflects on the strong concern of this natural phenomenon.
Total solar eclipse
Total solar eclipse is not a rare thing, about every year and a half on the world's first total solar eclipse occurs somewhere. When a solar eclipse occurs when the moon is running in the middle of the earth and the sun, the moon's shadow projected onto the oval-shaped surface of the earth. As the Earth and moon are in motion, so the moon's shadow swept very rapidly, the Earth's surface. Swept the region in projection, one can see the total solar eclipse. Swept this region a long strip of film total eclipse. As the total eclipse is very narrow, generally only about 200 kilometers, which is why on earth people in a particular region, the offer to 300 years to see a total solar eclipse.
During the total eclipse, people can see the sun's outer atmosphere. This layer of atmosphere called the corona, like the white color of pearls, feather-like features with fibrous material. No wonder the ancient Egyptians as a winged sun. They may be a total solar eclipse was observed in such speculations.
If you use a telescope or binoculars, you will see the corona in the wonderful scenery. Edge of the sun are likely to see pink prominences. Solar corona and prominences are an important feature. Occasionally you can still see the bright pink as the fountain-like prominences ejected from the edge of the sunspot. Solar eclipse occurred in a few minutes, these prominences appear to be immobile. Around the corona around the sun itself, the sun is the result of intense activity.
During the whole food, usually to see the corona extends to two or more parts of the radius of the sun. Another eclipse a solar eclipse and the corona seen the shape is different. We already know there is a cluster-like coronal structure from inside the sun and sunspots caused by a strong magnetic field at. The sunspot minimum period, it showed a long strip at the equator, in the shape of two very fibrous brush. Great period in sunspots, coronal almost symmetrical distribution, a bit like a dahlia petal shape.
Observing the eclipse eclipse observation in several ways. Direct observation with the naked eye is dangerous. In every solar eclipse, when there are people leaving the direct observation with the naked eye due to retinal damage. Crystal strong body of people, like the sun like a lens focusing on the retina. When look directly at the sun, it will burn the retina, damage to eyesight, severe cases can lead to blindness. In the partial eclipse phase, you can use binoculars to watch the projection method. Pinhole imaging method, dilution in the basin to put the ink method can also watch. The most common method is to use smoked glass disk plate core, photographic film or a welder's protective glass.
When a total eclipse occurs, you can watch directly with the naked eye. At this time the sun's light has been reduced to the extent of the full moon. Moon like a black plate blocking the sun's photosphere. The only visible to the sun's corona, a very nice sun's outer atmosphere.
Total eclipse, annular eclipse and partial eclipse
From the total eclipse or an annular eclipse with a nearby resident will see a partial eclipse. Partial eclipse at the poles is common, when the shadow on the near but not touching the ground. Whole Foods and annular eclipse occurs about once every 1.6 years. Partial eclipse will occur once only 1.33 years, but what it did the importance of scientific research.
Eclipse
Solar eclipse occurs when the new moon, which is lunar first day or so. Instead eclipse occurs in about 15 month's full moon. At this time, the moon into Earth's shadow. As the Moon orbits the Earth than the moon at the large projection, so the annular eclipse of the month is not going to happen. Total lunar eclipse occurs once every 13.5 months, the case of partial eclipse less, about 22 months. Although the frequency of total eclipse in less than a total solar eclipse, but living in an area for people who have the opportunity to see the total eclipse. To watch the total solar eclipse, you have to go there the narrow band to the total eclipse, and for total eclipse, as long as the half moon in the face of the earth people who can see. In eclipse, the Earth's shadow gradually eat into the lunar surface, the sky darkens. As the Earth's atmosphere on light scattering, so that the sun shines in the corner to the Earth's shadow on the moon, so the total solar eclipse of the moon's surface is not black but presents a bronze. Even if only through a small telescope to see the lunar surface is also very beautiful. For any year, will occur at least twice a solar eclipse, occurred up to 7 food: five or four times a solar eclipse solar eclipse eclipse twice three times eclipse. |
