Essay On Parker Space Challenger

The Aurora Australis is created by solar winds—continuously emitted stream of charged particles originating from the face of the sun. With periods of high solar activity, sunspots

On the other hand, the geomagnetic storms have been intensified and enhanced in their frequency as magnetic fields of coronal mass ejections indulges with that of the earth that causes change of direction and leave more radiation and magnetic energy into the environment of the planet earth. Solar Hemispheric Observatory and Solar

The history of our solar system is one topic that scientists were able to gain information on due to the Philae mission. “A Success in Space”, an article that reveals the story of the Philae one mission, states, “Researchers consider comets the remains of the ancient solar system.” (Keady 5) This quote shows that comets can be a key to finding more about the remains of the solar system from long ago. Ashley Yeager, the author of the article “Comet probe may shed light on Earth’s past” wrote, “By studying these hunks of rock, dust and ice, scientists hope to better understand the early history of the solar system—including Earth’s early years.” (8) This example proves that scientists hope that comets can help them assimilate more information on the history of our

In 2012 a solar storm nearly hit us and if it had hit us we probably wouldn’t be here. However, it completely missed us. Therefore, it is very important for us to understand the sun because it can put our society to its knees and cripple us for a very long

For this evaluation essay, I chose four sources for it. The first two material are a journal and one news about the definition of the Pluto. For the third one is a book of introduction of Astronomy, while the last one is a professional source for solar system. All of these resource are written by experts, but not all of them can be cited as an academic source in a research paper.

Sunspots are generated by strong and dense magnetic fields, and these magnetic fields are caused by flowing plasma that gets tangled and moves through the photosphere. [1] However, it is not actually sunspot activity that effects the Earth’s power grid and satellite communications, [2] but rather the solar flares and coronal mass ejections (CMEs) that can be caused by sunspots that cause problems. [3]

Solarwinds, a “stream of charged particles from the sun’s upper part of the atmosphere, called Corona”. They said to be made out of hydrogens protons and electrons. Also having a traces of atomic nuclei and alpha particles. The Astrophysicist who first discovered this amazing thing, formerly known as Eugene Parker. It wasn't until 1958 when notice,“stiff

Scared, worried and stress were some of the things that I felt at the time. My friends were doing all they could do to fix the problem. One was listening to whatever the engineers said while the other was trying to build a oxygen tank from spare parts we had in the shuttle. It had been roughly fifty six hours, and we had travelled two hundred thousand miles away from Earth. There is nothing or no one around us; just a empty, cold, dark void that surrounded us.

The purpose of this lab was to analyze data from the Sun at different layers of the atmosphere and gain knowledge about sunspots over time. The Sun is the largest object and the center of our universe and is composed of 75% Hydrogen, 23% Helium, and about 2% metals. Galileo was the first to observe darker regions on the sun with a telescope. These darker regions are called sunspots. Sunspots are “spots” on the Sun that appear dark then the surrounding areas due to their cooler temperature. The number of sunspots changes over an eleven year cycle.

Hydrogen and oxygen are the two elements that make up water – with the same observed ratio of two to one. Therefore, it has been concluded that water is taken off a planet’s atmosphere when solar winds approach it. Planets such as Venus and Mars are swept dry (hence their lack of water in their atmospheres) by the solar winds, due to the planets’ absence of magnetic shields powerful enough to “protect” them. The Aurora Borealis is a byproduct of Earth’s defense mechanism against the solar winds – the reason why Earth is not as dehydrated as its sister planets. This research paper will concentrate on the explanation as to why Aurora Borealis is formed.

This consists of two transponders that are responsible for radiofrequency on the planet. They detect signals from NASA’s DSN (space network of antennas and communication spaces) signals and immediately send signals back. Small changes in signal frequency show how much Juno’s speed changes due to variations in Jupiter’s gravity. This provides data that can be interpreted to understand the internal structure of Jupiter’s gas. The second portion of this goal’s methodology requires insight into Juno’s Magnetometer.

The solar wind containing these hot gases races toward the edges of the solar system, and smash in to the magnetosphere. The magnetosphere protects the earth by deflecting most of the solar wind around the planet. Trillions of these charged particles mange to get through and project from the North and South poles. Energy released in this fashion excites atoms of nitrogen and oxygen, which in turn emit pulses of colored light. These formations are called an aurora. The aurora borealis, which are visible in Alaska, are a result of this sort of space storm.

Sobral et al (2006) examined ionospheric response to high intensity long duration aurora electrojet activities. Using the equatorial, sub-equatorial and low latitude regions to observe their responses to High Intensity Long Duration Aurora ElectroJet Activity (HILDAA) between 2000 and 2001 on solar wind and interplanetary magnetic and electric field. The result provided a clear evidence of thermospheric wind and dynamo electric field perturbation in the F layer. The solar wind speed varies between ~350km/s - ~480km/s while the Dst index has a steady amplitude of －50nT. Sustained high intensity AE activity during HILDAA generate more disturbance equator-ward which is quite close or resembles that of the geomagnetic storm. Concluding that

Plasmasphere is a highly dynamics region which can expand and shrink within hours or less during geomagnetic active times. Previous studies showed that the plasmasphere plays an important role in energization and/or loss mechanism for electrons in the radiation belt. Therefore, constructing a plasmapause (the outermost region of plasmasphere) model is key to study the correlation between radiation belts and plasmasphere in details. This study aims to conduct a comprehensive analysis for plasmapause modelling by comparing the performances of different machine-learning techniques using different parameter sets. Particularly, this study examines techniques like bagging, boost, support vector machine, and neural networks and trained the models

Solar activity ejects solar wind or a cloud of gas called a coronal mass ejection. It takes 2 or 3 days for a coronal mass ejection to reach earth. The earth’s magnetic field gives earth a long magnetic ‘tail’ stretching a million miles behind earth in the opposite direction of the sun. If a coronal mass ejection reaches earth, it collides with with magnetic field and causes complex changes in the magnetic tail region (Lui, 103). The changes generate currents of charged particles. These particles flow along lines of magnetic force, converging towards the magnetic poles from all directions and resulting in an oval ring around each pole. Then, they are boosted in energy in earth’s upper atmosphere. Finally, they collide with oxygen and nitrogen atoms to produce auroral light. Colors and patterns seen in the lights are produced from the types of ions or atoms being energized as they collide with the atmosphere and are affected by lines of magnetic force. Altitude also greatly impacts colors. Blue violet/reds occur below 60 miles, bright greens are strongest between 60-150 miles and above 150 miles, ruby reds
