The Solar was first detected in 1896 by Kristian Birkeland, who proposed that aurorae were due to particles emanating from the Sun \citep{SternDP}. In 1958 Parker demonstrated that the wind is a result of high temperature of the corona and the low density in the ISM. The solar wind is made up of plasma which mostly consists of electrons , protons ans alpha particles with energies varying between 1.5 and 10 keV. This solar wind varies in density temperature and speed over time and longitude.\\
The Solar winds originate from the Solar corona (the outermost part of the Sun's atmosphere), where the outward force on the particles due to the magnetic field is greater than the gravitational force of the sun. These are highly ionised plasma which travel from the sun at supersonic varying speeds, depending on their origin. Low dense bubbles (astrosphere) are

The solar wind is a plasma and thus exhibits plasma-like characteristics. The winds are highly electrically conductive so that the magnetic field lines from the sun are carried along by the winds themselves. The plasma in the interplanetary medium is also responsible for the strength of the Sun's magnetic field at the orbit of the Earth being over 100 times greater than originally anticipated. If space were a vacuum, then the Sun's magnetic dipole field, about 10−4 Teslas at the surface of the Sun, would reduce with the inverse cube of the distance to about 10−11 Teslas. But satellite observations show that it is about 100 times greater at around 10−9 Teslas. Magnetohydrodynamic (MHD) theory predicts that the motion of a conducting fluid (e.g. the interplanetary medium) in a magnetic field, induces electric currents which in turn generates magnetic fields, and in this respect it behaves like a MHD model. The magnetic field modifies the plasma properties of the stellar
Radiation- the emission of energy as electromagnetic waves or as moving subatomic particles, especially high-energy particles that cause ionization. 13. Sunlight is a form of radiation that is radiated through space to our planet without the aid of fluids. 14. The sun transfers heat through radiation of space.

Sherpa fire in Santa Barbara grows to 4,000 acres overnight, putting about 140 homes at risk and closing down major freeways according to federal officials. The fire started on Wednesday afternoon on coastal hills north of Santa Barbara. It had moved through overgrown hillsides and canyons that have not been burned in over 60 years because of the hot and dry weather and notorious “sundowner” winds. Sundowners, similar to Santa Ana winds, fuel many of the fires in the Santa Barbara County.
However, a rotation curve of a rigid body must have a body where the angular speed is the same. As a result, this lab will help me understand how individual stars move in a galaxy spiral. This lab will also help me understand why the stars speed in the inner part is different from the outer part of the galaxy. Procedure
Comets are sometimes jokingly called “dirty snowballs”, but in light of current information they are more like snowy dirtballs. Comets are composed of dust, ice, carbon dioxide, ammonia, methane, and other materials. Periodical comets (comets that have a 200 year or less orbit span) are thought to have originated in a place called the Kuiper Belt, beyond even the orbit of Pluto. Non-periodical comets (comets with an over 200-year orbit span) are theorized to come from a mysterious place called the Oort Cloud, and some other comets called Sun Grazers are comets that either pass close by the sun or even collide with it, usually causing the comet to burn, evaporate, or even explode. One semi-famous comet, Shoemaker-Levy 9 crashed into the planet Jupiter in 1994 causing twenty-one visible explosions, the most massive of which made a dark spot on the planet approximately the size of Earth, and generating roughly the force of twelve quadrillion pounds of TNT.
Recent scientific research presented at the 52nd annual meeting of the American Physical Society’s Division of Plasma Physics shows that CMEs (as well as solar flares and other solar phenomena) are closely related to magnetic reconnection, a process in which two oppositely directed and stressed magnetic field lines are brought together, changing their patterns of connectivity in respect to their source. The rearrangement accompanies a sudden release of energy previously stored in the stressed magnetic
A ray is a beam of light shining from the sun and that is the
The currents existence was first suggested by William Saville-Kent in 1897. It was because satellite technology created in the 70's that scientists were finally be able to confirm the existence of the current. The current is pushed along with a north-southernly pressure degree and is, at its peak of strength from May to June, which
The energy that comes from solar radiation, as well as heat transfer, create energy which in turn creates temperature. Chapter 3- Temperature : All The temperatures around the world occur because of many reasons.
Entoptic auroras are illusions that can alter what we believe is real and what is imaginary. In some ways, this can affect the way we act and interpret a situation. The distortion of vision impairs our ability to process
Global climate change is a very serious problem that we must pay close attention to. The main reason that causes climate change is that there are too many carbon dioxide in the atmosphere. If the temperature keeps getting higher and higher, there will be many problems that can cause great damage to us and the environment. If we don’t replace fossil fuels with other clean energy, our Co2 level will be as many as the time of the dinosaurs and we don’t know what will our lives be if this really happened. The best way to solve this is by using solar energy.
Benefits of Grounding I. Grounding is a way of reconnecting to the earthing energy. Also is a good reminder that we all need the earth to survive and that we eat from the earth. What grounding does in that process of walking barefoot on the ground is it gives the free electrons from the earth and brings it to the body and the surface of the red blood cells. The health benefits of daily grounding include decreasing stress, strengthening and stretching in muscles, while also decreasing anxiety and depression.
The gravitational pull of Saturn and its moons on the ring particles causes some interesting patterns to form in the rings and these patterns are so called “waves” which are really tightly-wound spirals. The gravitational pull of both Saturn and its moon form two types of waves normally on the rings which are "spiral density waves", and "spiral bending waves" (as per the location of the moon around the rings). Now scientist and researchers are focusing their study toward Saturn’s rings and its moons. This research may help to predict the presence of rings and the source of ice in the rings. This can also explain about the formation of rings around other planets like Uranus, Jupiter and Neptune, and distant asteroids Chiron and Chariklo.
Scientists have found that renewable energy is a path towards the future for a clean and safe environment. Throughout all the studies and findings, there is a continuing fret whether people should be able to use a traditional way of energy or renewable energy, solar power. Solar energy is seen to be effective since there has progressively been more places that are benefiting from solar usage; however there are also some who disagree. Solar energy sources are derived from natural sources and is implicated throughout our daily lives. From the lights in the streets to the computers we use at home.
“Renewable energy resources that is naturally regenerated over a short time scale and derived directly from the sun, indirectly from the sun or from other natural movement and mechanisms of the environment. Renewable energy does not include energy resources derived from fossil fuels, waste product from fossil sources, or waste products from inorganic sources.” There are a few types of renewable energy sources. 1) Wind Energy 2) Biomass 3)
