Solar Wind

Decent Essays
The Sun, the closest star to Earth, and a life-sustaining necessity. It is also the center of space and solar weather, which powers and affects much of the solar system’s activities and life on Earth. Space weather goes hand in hand with the Sun’s constant gaseous activities, which depend on the Sun’s natural occurrences. This paper discusses the important topics of solar plasma, solar wind, as well as solar flares and coronal mass ejections. It also looks at human abilities to capture and use solar wind energy to further space exploration and travel in more efficient techniques and methods. Space weather produces different types of solar activities that affect our Earth and those in space. Most inherently, the interactions between solar wind …show more content…
Similar to the process of solar flares, solar wind is created by pushing energy to the surface of the sun, the corona. The corona is what visible light we set of the Sun during a solar eclipse. From there the force of the flow ejects millions of tons of plasma into space every second. It creates giant streaming clouds of exhaust gas that can reach temperatures in the millions of degrees Fahrenheit. Temperatures at the surface of the Sun are so hot, that the Sun’s gravity can’t hold on to the rapidly heated particles, thus they rush away from the star. Speeds can reach up to 500 miles per second. The wind primarily consists of charged particles, composed mostly of electrons and protons. These fast moving clouds vary in shape, size, and power. As these clouds move away from the Sun they can change speeds, and carry magnetic clouds from the magnetic fields of the Sun. In the beginning, solar wind greatly affected the shape of the solar system. Its power has stripped the once water abundant Mars and turned it into the dusty red planet it is today. Each planet can be affected differently given their magnetic fields and …show more content…
About 30 CMEs hit Earth every year, but not directly enough to have a severe impact. Larger CMEs are a once-in-a-hundred year accordance based on past data. Even small CMEs could take out entire electrical grid and community communication systems. A large CME could have potentially severe effects which could wipe out entire areas of electricity or communication without restoration for decades. Human life would be set back to independent times, where business, medical, commerce, and agriculture would resort to past practices. However, it would not have effect on health for humans at Earth. Due to relatively low orbit, astronauts in space are still at little to no risk of harm. Humans traveling out of the safety of Earth, like a mission to Mars or the Moon, would be at risk for severe radiation poisoning from sun particles if unshielded at the time. Astronomers and scientists, like those Space Weather Prediction Center, are constantly monitoring the Sun from Earth as well as space laboratories and devices. Scientists can see the solar flares and CMEs ejecting from the Sun, and can possibly warn satellites to shut off their power and remain safe. A CME can not be prevented, but we have notice a few days before hand to prepare. Governments are now paying more attention to issues with possible CMEs or solar flares, and are investing in new technologies to protect power grids

    Daniel went to check the telescopes. There are several reasons that why the astronomers and the scientist chose the far side of moon to place radio telescopes. It is predicted that on the far side of the moon, there will be extremely high concentration of helium-3 because the solar wind, the stream continuously flows come from the Sun with the speed of 400 km/s, containing lots of plasma, electrons, protons and charged particles, was stopped by the Earth’ magnetic shield [14]. Therefore, it naturally forms a perfect surrounding…

    1. Introduction The tides are a regular and predictable phenomenon caused by the gravitational attraction of the moon and the sun acting on the oceans of the rotating earth. Tidal flow affects the daily dynamics of ocean. In fact, it is the largest source of causing of sea level change besides wind and barometric pressure. The purpose of…

    Solar Winds and the Martian Atmosphere The suns steadily releases charged particles from its upper atmosphere through the Solar System by solar winds. These winds have different effects depending on the properties of the planet. Earth, for example, has a very strong magnetic field as a result of a multitude of factors. Mars on the other hand does not have a strong magnetic field protecting it from the solar winds. It is believed that Ancient Mars had rivers and lakes, however it died billions of years ago after the bombardment of solar winds eventually depleted the atmosphere to create the version of mars that we know of today.…

    This new science has lead us to believe that the sun has a lot of layers. A zone of perpetual churning, a place where light takes thousands of years to cross and the center of the sun is the core which is made of plasma. This plasma is radically hotter in the sun’s core than any normal plasma, because of this activity and how hot the core gets. We as ourselves why does the sun not blow up. It is because of the pressure pushing downward as the sun is pushing outward causes a balance which allows it to not blow…

    Dangers Of Solar Winds

    The sun is the star we are orbiting, which gives us heat and more stuff. Of course, it is also potentially dangerous, it can cause skin cancer, solar winds, too much heat, and it will obviously end up destroying the earth in a few billion years. I am especially studying the solar winds, this is because I think that solar winds are more interesting than the others because they look as if they were more fun and had more things to talk about. The problem with solar winds is that they come to the earth from the sun and they are highly charged and can take down electric systems and can maybe even kill humans. Of course, we have a magnetosphere which protects us from this danger, but not completely, there are still dangers like when the solar winds…

    The greenhouse effect is a naturally occurring process within our atmosphere, it aids in heating the earths surface and atmosphere. The greenhouse affect is caused by the fact that certain atmospheric gases, gases such as carbon dioxide, water vapour and methane are able to change the energy balance of the planet by absorbing long wave radiation emitted from earth’s surface. Without the greenhouse affect our earth would be a chilly -18°C in comparison to the present average temperature of 15°C. As energy passes through the atmosphere a number of different changes take place. 26% precent of the suns energy is radiated back into space by clouds and other atmospheric partials.…

    The spark of the collapse could have been caused by a galaxy collision, or the shockwave of a neighboring supernova. This collapse causes the cloud to break into fragments. These fragments start to grow as more and more molecules start to attach creating a protostar. The new star starts to increase in temperature, because of the switch from gravitational energy to kinetic energy. The start hasn 't yet gone through nuclear fusion making the star weak and unstable.…

    The huge pressure forces caused by the air resistance as the asteroid comes through the atmosphere at very fast speeds, causes the asteroid to explode. (10) But with the Chicxulub impactor, the energy, air friction and speed in the impact would have vaporized the asteroid after it hit Earth, along with a large amount of the Earth's crust. This happened because the asteroid was much larger in diameter than most objects that collide with Earth. The impact caused a crater 185 kilometres across to be left on the Earth’s surface and all the left over rock to be thrown into the…
