Sample Astronomy Essay on Your guide to the moon

Your guide to the moon

The moon just like other components of the solar system is very important especially to life on earth. In most cases people tend to think that the moon is in constant motion due to the fact that when just viewed literally it seems to be moving. However, the scientific evidence over the same totally disapproves this idea. Actually it is the earth that rotation and the revolution of the moon around the earth that bring about the different phases of the moon. The article your guide to the moon tries to bring out a lot of understanding on the nature of the moon in different phases in comparison with the normal theoretical approach that most people have. The article describes the texture of the moon in different phases indicating that, even in the moon there are some land forming process that take place just like on earth. This is supported by a clear indication of some land forming features described within the article in various phases of the moon such as volcanic activities, the crater floor and the scattering of dark cinders.

Overview of the article

Major themes of the article focus on the characteristics of the different phases of the moon such as the crescent moon, first quarter moon, the waxing gibbous moon, the full moon, the waning gibbous moon and the last quarter moon. The article also focuses on various events of these phases of the moon and the methods that can be used such as the use of the telescope to view all these phases of the moon. For instance, characteristically, the last quarter of the moon is marked by the dark larva while the waning gibbous moon is marked by the shading off of the bright rays. The story line of the article is supported by various pictorial presentations to ascertain some of the facts within the article. These act as strong supporting evidences to the information contained in this article.

Evaluation and analysis of the article

At the beginning, the article highlights a number of facts on the new moon which is also described as the crescent moon. The crescent moon is seen four days after the new moon and mostly occurs when the moon passes between the sun and the earth. During this time a bigger portion of the moon experiences partial darkness. This is a phenomenon described by some articles as the umbra and the penumbra. According to this article, this time is referred to as the lunar cycle, a time when the portion of the moon illuminated by the sun’s rays is very small and it is experienced at the beginning of every month. At this point of time, two seas are observed; the Mare Crisium and Mare Fecunditatis which is described to look as sea bed. The formation of lunar crater is seen to be as a result of impact by the gigantic meteorite. As described in other articles by various scholars, the lunar surface is seen to be rough and with a lot of depressions. These are referred in this article as crater which is generally light in tone.

According to the article, the older surface of the moon can be identified by the number of craters it bears. This fact has been proved by the rule of thumb showed by many scientists who studied the moon before. In relation to this article, it is evident that one can easily identify the ages of various craters of the moon simply by having a glance at two different areas.  The pictorial presentation of the article indicates clearly the differences between the two. In this case, the youngest lunar craters are seen to be small than the oldest crater simply because of first collision of the largest debris with moon and other planets. Basically, it is always difficult to observe this phase of the moon since at this stage the characteristic features are not clearly visible. A technique given in the article best explains how this can be possible simply by placing the telescope outside for half an hour to ensure that the tube cools to avoid distortion of the image by the air current inside the tube.

In most cases, it is always difficult to differentiate between the crescent moon and the first quarter moon. Most people often confuse the two phases. However, according to this article, it is the time the moon is seen to have completed the first quarter of the monthly orbit and it is usually on the seventh day after the new moon. It is the best time to explore on some of the features of the moons eastern hemisphere. Telescopic examination of this phase reveals that there are flooded fracastorius which indicates mare larva flows. In fact, this is the time Nectaris are seen to be showing the structure of the basin clearly. In this phase, most geologists describe the land scape as saturated with craters. This is supported within the article by pictures of the land which are actually seen to be having a number of craters in page four of the article.

Nine days after the new moon, another phase is seen. This is referred to as the waxing gibbous moon according to the article. In most cases it is the time that most features in the moon are seen to be diminishing. This is due to the power of the sun as it climbs up over these features with the rays of the sun flattening the terrain. Generally, the moon at this point is brighter than the previous phase. As the article describes, the prime features at this phase is the Mare Imbrium and the related features that surround it. Most scientists describe this phase of the moon as magnificent. This is evident from the article based on a number of magnificent features highlighted from the north to south, east to west. For instance, the dark straight line seen on Mare Nubium that is running roughly from north to south is very outstanding. These features are well indicated in pictorial form within the article for example the black line and the hidden highlands among other features.

 

The full moon appears 14 days after the new moon is seen. Most people tend to think that it is the best time to see almost every feature of the moon but according to the article, this depends on the features to be observed. For instance, features like craters and mountains cannot be seen at this time. The only features according to this article that are visible at this time are the rays and the lava flows. Several people tend to think that the moon generates its own rays but according to this article it is evident that the rays are just a reflection of the suns rays which hit the craters and then are reflected on the earth’s surface. The Tycho is seen to be surrounded by a dark ring which studies from other sources show to be the glassy impact of melted rocks. The images shown by the articles indicate how the Aristarchus appears bright and how magnificent the ring around the crater appears and it is often advisable to observe the moon at this time using sunglasses.

When the bright rays of the moon disappear, it is likely that the waning gibbous moon will be seen. According to the article, it is observed on the 20th day after the new moon and it is marked by the fading of the bright rays and the emergence of the relief features that disappeared when the sun was high. This phase is marked with the dark splotches, valleys and sculpture around Mare Vaporum. Analysis of the article indicates that this is the time the low angle of the sunlight in a very beautiful way reveals the Theophillus, Catharina and the Cyrillus and the terraces found within their walls and central peak. Towards the end, the article describes the last bit of the moons cycle as the last quarter moon which begins 22 days after the appearance of the new moon. Many people fail to notice this quarter of the moon but the article describes it as the perfect moment to explore number of features in the southern highlands that appear to have been washed out in the cycle earlier. The low sun angle in this quarter is seen to reveal details of Aristarchus and the surrounding. The larva is seen to darken as evident by the picture in page 13 of the article. It is described as the lunar sunset characterized by the growth of shadows that hides the moons awesome starkness.

 

Comparison with academic and popular magazines

Based on the analysis of this article, it emerges that there are a number of issues that have not been addressed by most articles, magazines and even books. Most articles focus only on the three phases of the moon which are the new moon, the full moon and the final crescent moon. However, the article reveals that there are almost six phases of the moon with each phase characterized with a particular event. The mode of presentation on a number of activities taking place within the moon has never been exploited by other articles as compared to this. For example it is true as per other articles that the moon does not produce its own light but reflects the light from the sun to earth surface. However, in others articles it has never been clear how the reflection takes place. But the findings from this article reveal that the reflection is actually from the melted larva within the craters that bounces back the suns rays on the earth surface. Another finding from this article is that just like other planets, the moon also has a rugged terrain, volcanic activities and relief features such as mountains and valleys among others. However, the absence of gravitational force in the moon and the effect of the same on various activities in the moon is still a subject of discussion.
