Introduction:
Astronomy is derived from infancy of human culture--- ancient age. People pay more attention to observe sun, moon and star by positioning their location and making calendar in order to indicate direction, ensure time and season. In some point of view, astronomy is one of the most old subjects in Neurology. Sun, as one of the most vital origins that providing light and ultraviolet rays, is actually an very huge galaxy, its cycle was found by a amateur astronomer, Henry Schwab. In 2010, America SDO detector has foretasted the influence the movement of Sun to Earth. Moon is a solid satellite encircled Earth. The one is the closest celestial body and have a profound relationship with Earth, its age has already been 4.6 billion years.

The mean thickness of outermost lunar shell is nearly 60-65 kilometers. 100 depth under the shell is lunar mantle, which occupied most volume of Moon. Afterwards, lunar core hides under its mantle, which has very high temperature of 1000 degrees. The average diameter of Moon is about 3476 kilometers, which is 3/11 of Earth and 1/400 of Sun. When it comes to its volume, it only account for 1/49 and the quality is also 1/81 of Earth, which is 7350 tonnes.
Temperature:
Due to the fact that lack of air in Moon with low thermal capacity and conductivity of lunar substance, the temperature between day and night has change a lot. In day, the temperature can be positive 127 degrees centigrade when sunlight irradiate with vertical. However, it is probably minus 183 degrees centigrade in the evening. Those statistics only show the temperature of lunar surface. Therefore, lunar soil temperature can be measured by radio detectors, it proves that there are little changes in soil, that is why the themal conductivity is so low.

When the sun is acute, especially the solar flare, sensitive X rays, ultraviolet rays and so on from sun make the ionosphere’s D level be more thicker, which enhancing long wave, however, the short wave reflected by E and F level has attenuated because of strong absorption by D level. Time later, the energetic particle solar flare produces arrives the earth, it towards geomagnetic poles because of earth magnetic field, therefore, it influences ionosphere and causes interference of radar and radio communication in high latitude
Ancient Pueblo Indians had a great understanding of astronomy. All of the pueblos in the canyon were aligned to match the movements of the sun and moon. Also, they marked their complexes with daggers and spirals to keep up with the moon cycles and sun movements. The film explains that the moon moves north for nearly ten years and then south for about ten years. To fully understand this cycle of the moon, Pueblo people had to study it for years in order to build their Pueblos in relations to it. The sun however, was different because it set and rose in the same position. The concept of building structures in an astronomical pattern this complex cannot be found anywhere else.
Little to no change observed in an hour. The distance between the Earth and the Moon is 11 squidgits.
the moon exerts a much stronger gravitational effect on the Earth than the Sun, dominating the ebb and flow of
What is astronomy? Astronomy consist of a lot of things that make up our solar system such as: the nine planets, asteroids, meteorites, the moon and the sun. Astronomy is also a fascinating hobby that can be followed by anyone. You do not need to be, as some people seem to imagine, ‘mathematically-minded’ , in order to start, or even to become a very experienced observer. Yet astronomy is one of the few hobbies where not only can you gain great enjoyment, but if you feel want to can very easily make observations of great scientific value.
The Earth’s moon is a rare body and there are very few similar to it. NASA has sent many manned and unmanned missions to Earth’s moon in order to answer the many questions they have about its composition and how it got there. The data that these missions yielded helped astronomers to develop these five theories:
Especially as there is practically no evidence left on the Earth from when it was initially created. Most of the evidence, long gone due to the Earths extremely rocky start though constant meteoric attacks, different life inhabitants, etc. The fact that the moon is essentially a fingerprint of the Earth holds many answers to the mystery and allows science to further go in depth to what things were like for planet Earth billions of years ago. It has been found that the creation of the moon itself was caused by high impact into the planet, the moon has also been determined to be moving further and further away from the Earth which slows down the Earth’s rotation, and lastly that because of the moon the Earth has stable seasons which prevents the planet from either being a big burning wreck which is inhabitable to humanity, or a giant ice ball which is also inhabitable to humanity. All in all, as discovered in the film “Origins, fourteen billion years of cosmic evolution: Earth is Born” the moon is a necessary part of our planet and one of the many keys to unlocking its many
Because the Sun is so influential, imperfections of the Sun, such as sunspots will continue to impact life on Earth. The discovery of sunspots is correlated with the invention of the telescope in 1608, although there are earlier recordings of sunspot like activity from China (Schaefer 35). Galileo was one of the astronomers who decided to publish his findings and use sunspots in one of his theories of Chief World Systems (Schaefer 35-6).
Astronomy is a very important field in science. Ancient Greece, China, and India all contributed to our everyday ideas and uses of astronomy. Ancient Greece was the most influential because the Indian’s based most of their astronomy off of Greece. The Greeks created calendars that were based off of the eclipse cycle, which they called by two different names, Hellenic Calendars and Lunisolar Calendars. Because of Ancient Greece, we now have calendars to keep us on track every day. The Greeks observed a celestial object passing through the eastern and western morning sky. After a long time of observations, they came to a realization that it was a planet and now that is the planet is well known as Venus. (Sarton, 75) Plato and Aristotle’s theories were incredible contributions on us today. Both of their theories were all about the behavior and life of the planets, such as their theory that the earth is spherical. (Sarton, 421). Ancient Greece als...

The moon is probably the most noticeable object outside of earth atmosphere besides the sun. There are a great number of facts about the moon. Most of these facts include size and distance of the moon compared to the Earth. Our moon's proper name is "Luna". Luna is 238,900 miles away from earth, and 27% smaller than earth. The moon is the most studied object outside of earths atmosphere. Luna is the only naturally made object that humans have set foot on besides earth.
The moon is a wondrous thing. Every night it's outside, up high in the sky, giving light to the world. Most people take advantage of the moon's light, because they don't know why or how the moon shines. Scientists today are busy proving theories and studying the moon, which will hopefully help society to understand the moon more. They know a lot about the moon, but there is still much more to learn.
Analysis and Conclusion The moon was observed during the time period of July 21 – July 31. As we already know, the moon travels around earth at contestant speed going from east to west. During observation we noticed moon changing location in the night sky from night to night. Also when looking at the moon in same location, the moon appeared to be moving from west to east.
One thing us humans have never been able to fully understand is astronomy. Always an unexplained mystery, astronomy also serves as a way to keep time and predict the future. The word “astronomy” is defined as the study of heavenly bodies, meaning anything in the sky such as stars, galaxies, comets, planets, nebulae, and so on. Many people, if not everyone, are amazed by the night sky on a clear, moonless night. Astronomy dates back to ancient times when peoples such as the Babylonians, Egyptians, and Chinese kept written records of astronomical events and occurrences.
The moon is much smaller than the earth is, in fact the earth is more than one quarter of the size of the earth. The fact that the moon much smaller means that there is much less gravity on the moon than we have on earth, though, there is still gravity on the moon. The amount of gravity on the moon is one sixth of the amount of gravity we have here on earth. On the moon, there are only two types of regions, however, despite the fact that there are just two regions, there is much more to the moon than just those two regions. Many things can be found on the moon, such as, craters, lava plains, and mountains.
When a solar flare occurs, vast amount of magnetic energy get released and turned into electromagnetic radiation. (NASA 2015) Traveling at light-speed, the resulting radiation containing X-ray, extreme ultraviolet rays, gamma rays and radio waves would arrive at Earth after only 8 minutes. The x-rays may interact with the atoms in the ionosphere of Earth and cause a sudden increase in ionization, which could interfere radar and shortwave radio communication. The ultraviolet rays can heat the upper atmosphere, causing the atmosphere shell to expand, which may drag low orbiting satellites and spacecraft, leading to unexpected orbital changes (Marusek 2007). For instance, the premature demise of the Solar Maximum Mission in 1990 and Skylab in 1979 are due to this phenomenon (Odenwald
