Astronomy Essays

The paper "The Hubble Deep Field: The Most Important Image Ever Taken" is a great example of a movie review on astronomy. The video entitled “The Hubble Deep Field: The Most Important Image Ever Taken” proffered pertinent issues relative to the magnanimous expanse of the universe. Each minute element is intricately related as part and parcel of what the universe is composed of.

Erosional activity on planets is affected by weather-driven conditions such as wind, rain, ice, snow, etc., geological activity such as movements of the crust, earthquakes, and volcanoes, the flow of liquids. Significant erosion, therefore, occurs if there is an atmosphere, geological or tectonic activity, presence of liquids on the surface and if life forms are present on the planet.

Astronomical artifacts including the Egyptian monument have been left by the prehistoric cultures to performed night sky observation. Before astronomy was able to undergo development into modern science, telescope invention was required. Historically, astronomy included disciplines that were diverse as astrometry, celestial navigation, observational astronomy and calendar making.

Theories that explain origin of the moon Distinct characteristics of the moon. Physical characteristics of the moon (Reid 161-163) In conclusion, we shall focus on differences between the moon and the sun regarding Physical characters Theories that explain their origin

We owe a lot to Galileo Galilei, Tycho de Brahe, Johannes Kepler and Isaac Newton for the acceptance of heliocentric concept. Galilei made this theory widely known. Tycho Brache’s observations of the planetary movements and Kepler’s works on the same subject contrasted with geocentric theory held by the majority of scientists and the Church of that time.

According to Russ Rowlett of the University of North Carolina, 99942 Apophis Asteroid has reached the highest level on this scale with level 4 only for a brief period in December 2004. Initial observations of the asteroid suggested a small chance that the asteroid may strike earth probably on 13th April 2029.  

The same way a planet which revolves around the sun in fixed orbits also has energies which are the sum of the Kinetic and potential energies. The kinetic energy of a planet is the energy processed by it due to its orbital motion which can be calculated using the formula KE = 1/2 mv2 where’ is the mass of the planet and ‘v’ is the velocity.

Famous personalities that contributed to the science of astronomy include Pythagoras, Aristotle, Aristarchus, Eratosthenes, Ptolemy, Galileo, Kepler and Isaac Newton amongst others. Modern astronomy began about 1300 AD in Europe. Almost all galaxies appear to be moving away from the world according to Edwin Hubble. 

In nuclear propulsion methods, it can be seen that nuclear radiations are being used as an effective energy reservoir but here again the radiation can cause a real threat to the survival of human beings on the earth. As proved by the relativity theory it can also be noted that an object can never have a faster speed than that of the light.

The author states that the travelers want to take the moon because they want it to place in their land that does not have a moon, as well as to bring it to their magistrate and eventually give light to the entire land. The travelers planned to get the moon during the daytime and will tie a rope in the oak tree.

Observations have been made to indicate a micro-world underneath all matter, a world of components of quanta. After the development of quantum theory, many scientists have a devolved mind on accepting the atomic nature of the electromagnetic spectrum. The subject of quantum theory is speculated upon and studies have been adopted to indicate a strong view.

In 3rd century BC, Aristarchus of Samos anticipated this and later it was supported with the mathematical model by the great mathematician and astronomer Nicolaus Copernicus. This was further sustained, intricate and lengthened by J. Kepler and Galilio Galilei who discovered telescope to prove that Earth and other planets revolve around the Sun.

Astronomy is among the oldest science. Astronomical artifacts including the Egyptian monument have been left by the prehistoric cultures to performed night sky observation (Renner et al., pg. 617). Astrometry is the term used to refer to the most ancient form of astronomy. It includes the measure of the moon, planets, and sun.

The author states that with the marking of the SN 185 the record was kept in the book of the Roman literature. RCW 86 proofed to be a remnant which appeared in correspondence to the latest years. The guest star also appeared that recorder the latest constellation of the Scorpius. The information was recorded over 20 ideas of events.

As the paper outlines, Titan is known to be composed of 50% ice and 50% half rocky material. Titan is similar to other moons of Saturn. Unlike other moons, Titan is dense due to its higher gravity and large size. The atmosphere of Titan is composed of double cloud layers of 200km and 300km, which is equivalent to 125 miles and 186 miles respectively above the surface.

Callisto is a moon found in planet Jupiter. It is termed as Jupiter’s dead moon. Callisto is the oldest landscape as well as the most greatly cratered body in the whole of the solar system and also has the. It is called Jupiter’s dead moon because it is thought to be long dead with no geologic movement on its entire surface (Zimmermann).

The question of what to do after finding evidence of life elsewhere fascinates many. This may include many benefits, some of which are also identified by Hurowitz, like once life gets detected on some other planet, that may include a solution to high gas prices or in my personal opinion, that may also include solutions to many problems on Earth.  

The solar system is made up of eight planets with the exception of Pluto. These planets are classified as either terrestrial or Jovian planets. Terrestrial planets comprise of Mercury, Venus, Earth, and Mars. Jupiter, Saturn, Uranus, and Neptune make up the Jovian planets. Atmosphere involves the gases that surround the surface of any given planet.

Elongation: From Mercury to Venus is 24 0. (The first two blanks are for the names of the two objects, planets) between which you’re measuring the elongation.)

Venus, moon, and mercury don’t have or comparatively negligible erosion because of the absence of atmosphere and also their closeness towards the sun. Wind may not be as prominent as that of the earth in these planets and hence the erosion process also may not be there. The extreme heat makes the erosion process almost impossible in these planets.  

The adoption of renewable energy is an appropriate way of reducing carbon dioxide accumulation in the atmosphere. One of the best sources of renewable energy is the use of solar energy. Solar energy is free, clean to use and affable to the environment hence if all people adopt the use of solar energy for both commercial and domestic purposes.

Certain factors like wind, changes in the climate, as well as surface liquid must be present to cause glacial movements. However, the atmosphere must also be matched with the right weather conditions that may cause a stirring on the surface thereby resulting in erosion. The heat emitted within the planet also contributes to erosion.   

The author points out that the internal heat that makes the earth’s lithosphere comparatively thin, core melted, and attribute to the consistency of its magnetic field. In addition to this geological source of heat, the earth is affected by the solar heat which makes the environment biologically active.

Kepler introduced the law of motion and described how satellites revolving the sun and how the moon orbiting the earth. Galileo invented telescope and made star observation rather easy. However, the Catholic Church which was the emerging political and religious power of the age opposed and persecuted Galileo for his theory.

It's pointed out that Earth’s atmosphere allows for wind and rain and such, causing erosion, and yet Mercury and the Moon do not have the appropriate atmosphere. Venus, however, has a small amount of erosion, but because the atmosphere is dense and sluggish, the erosion process is very slow and hardly noticeable.

Starlight is made up of radio, visible light, Ultra Violet, X-ray, infrared and gamma rays. Astronomers observe and utilize all kinds of rays. On earth, Astronomers utilize radio telescopes and visible-light telescopes whereas in orbits depending upon the reality and need astronomers utilize IR, UV, X-ray and Gamma-ray "telescopes" or detectors.

The author states that there are factors that play their role in eliminating erosion on other planets other than winds and rain. These factors include and are not limited to the composition of those planets, their internal chemistry, and their interaction with the environment and other planets.

The author states that Pisces is located between Aries and Aquarius on the southeast of Pegasus. In this space, it occupies an area of approximately 889 square degrees, and it is characterized by five stars with known planets. While in a clear, dark site at night, it is possible to locate Pisces at latitudes between -90o and -65o.

The caves can be estimated in depth and width, but such estimates are only a guess.  These skylights are holes in the roofs of caves.  Dennis Mitchell’s 7th-grade science class at Evergreen Middle School in Cottonwood, CA discovered these openings on the red planet.  There were a total of 16 students in the class (Moskowitz 2010). 

It simply defines changes in the surface of the planets caused by diverse factors such as water, wind, or ice (Pearson Education, Inc. 18) More specifically, it is a “blanket term for weather-driven processes that break down or transport rock. The processes that cause erosion are glaciers, rivers, wind.” (Pearson Education, Inc. (PEI) 25)

Plato presents his perception of the universe in the Timaeus. According to him, the universe is the handiwork of a divine Craftsman. Mathematical order has to be imposed on this universe, which is besieged with pre-existing chaos and this generates an ordered universe.According to Plato, the universe is unchanging and the true knowledge remains same in every place at every time, education too should be unchanging like the true knowledge.

Copernicus’ contributions to astronomy can be properly characterized as revolutionary on the basis of the principles of Thomas Kuhn’s structure of a scientific revolution.  Kuhn, a respected American philosopher, defined a scientific revolution as something in which a new paradigm or model takes over an older one.

Everything is attracted to everything else in the cosmos. When an object is orbiting around another object it falls around the object. That’s right. It’s perpetually falling, but never actually hitting it. Over some time, gravity takes its toll and little by little distance between the orbiter and orbited decreases until they finally meet.

Some of the instruments that will be used in Neptune’s moon Triton exploration may be basically the same as the instruments used in the previous explorations of the planet. On the other hand, there needs to innovate more of these instruments in order to adapt to the extremely low atmospheric temperature of the moon.

According to the author of the text, stars appear as twinkling to us because they are at a far off place from our earth and the atmospheric conditions, diffractions etc. lead to the phenomenon of twinkling. Actually, light is an electromagnetic wave that can be ‘seen’ by us. Reportedly, there was much discussion over whether light is composed of particles or waves.

Zooniverse is made to involve the public in observing and analyzing the data from different missions. The main project on the site is to analyze the radio signals from external planets already discovered by Kepler Mission since they provide a higher probability of receiving a signal by concentrating radio efforts at a particular area.
