What did the Explorer 1 discover in October 1 1958?
Once in orbit, the cosmic ray equipment of Explorer-I indicated a much lower cosmic ray count than had been anticipated. Dr. Van Allen theorized that the equipment may have been saturated by very strong caused by the existence of a belt of charged particles trapped in space by the earth's magnetic field. The existence of these Van Allen Belts, discovered by Explorer-I, was confirmed by Explorer-III, which was launched by a Jupiter-C on 26 March 1958.
Where are the Auroras?
The constituent particles of the solar wind are trapped by the earth's magnetic field and enter the earth's upper atmosphere as aurora. It is described as aurora borealis in the northern hemisphere.
Why are the northern and southern lights found primarily at the poles?
Streams of solar particles are ejected in space during solar flares which are seen as Aurora Borealis (Northern lights) and Aurora Australis(Southern lights) because the solar particles are trapped in the concentrated earth's magnetic field which is the strongest at the two poles of the earth only and not at the equator where the magnetic field is the least.
What problems do solar winds cause for some technologies?
Solar wind is a stream of energetic charged particles emitted from the sun. Their energies are many times stronger than X-rays, the common man-made radiation on earth. The earth surface is mainly protected with the earth's magnetic field. Most harmful particles are trapped or deflected away from the earth when they are approaching the earth's magnetic field. Above the atmosphere where the earth's magnetic field is weak, the satellites or astronauts will be bombarded with lethal particles and can suffer irreversible damage. Integrated circuits (IC's) on a satellite cannot survive solar winds for long. Once a critical IC is fried, the satellite may become inoperable. IC's and humans don't survive without heavy protection out there. Satellites closer to earth will have a lesser chance of being hit, but their brains (IC's) still need protection from prolonged radiation. On the ground, unless the earth's magnetic field has an anomaly, humans and IC's are both quite safe from the effects of solar winds -- no extra protection needed. ===========================
What is the difference between atmosphere and magnetosphere?
Atmosphere is the gaseous mass or envelope surrounding a celestial body, especially the one surrounding the earth, and retained by the celestial body's gravitational field. The air or climate in a specific place. While the magnetosphere is an asymmetrical region surrounding the earth, extending from about one hundred to several thousand kilometers above the surface, in which charged particles are trapped.
Why do charged particles from the sun (the solar wind) get trapped in the van Allen radiation belts?
The Van Allen belts are caused by Earth's magnetic field. Charged particles are deflected in the presence of a magnetic field.
How does the suns magnet field affect the Earth?
The sun produces energetic and charged particles and blasts them in all directions (solar winds). These charged particles can get trapped when they are near the earth's magnetic field. With the grace of this magnetic field, we are all shielded from being irreversible harmed. See the picture in the related link for a visualization of how the magnetic field gets distorted by solar winds. ============================
What are the earths two kind of protection against solar winds?
Earth itself is largely protected from the solar wind by its magnetic field, which deflects most of the charged particles; however some of the charged particles are trapped in the Van Allen radiation belt. XxBaby Dee
When the solar wind reaches earth charged particles are deflected from earth and trapped in two huge rings in earths magnetic field called what?
Those are the Van Allen belts.
What are the bands of Solar particles trapped in the magnetic shield called?
Van Allen Belt
Is the Aurora created by the thermosphere?
No. it is created by the Earth's magnetic field, and particles trapped in it from the Solar wind.

Particle accelerators use electromagnets to change a direction in which charged particles travel How does a charged particle move within a magnetic field?
The full motion is F=qvB where v and and B are vectors and the full motion is F= -qv.B + qvxb = qvB(-cos(angle) + vxBsin(angle)) there will be a scalar parallel to the field and the vector motion perpendicular to the field. This scalar field and motion is the real cause of so-called trapped particles. The vector motion is that of a mass spectrograph. The charged particle moves in a circle when perpendicular to the magnetic field.
How do the northern and southern lights form?
The northern and southern lights, also known as auroras, are created by solar wind particles interacting with gases in Earth's atmosphere. When these charged particles collide with gases such as oxygen and nitrogen, they emit light, creating the colorful displays we see in the sky. The Earth's magnetic field guides these particles towards the polar regions, which is why auroras are most commonly visible near the North and South Poles.
Where are the Auroras?
The constituent particles of the solar wind are trapped by the earth's magnetic field and enter the earth's upper atmosphere as aurora. It is described as aurora borealis in the northern hemisphere.
How does the sun affect the earth's magnetic field?
Well, imagine the Earth's magnetic field is an umbrella, its a fairly sturdy umbrella so most of the Solar Wind is deflected off and around the Earth. But some of the Solar Wind gets past the magnetic field at our poles which is what causes Auroras. Solar Wind tends to rip at Earths magnetic field, it acts sort of like a flag on a windy day. Blasting and flailing in different directions as the Solar Wind rushes past it. There are a few good videos on utube if you want to check it out.
What causes sunspots to be colder than the surrounding areas?
Sunspots are areas on the surface of the sun where strong magnetic fields keep charged particles trapped. Matter on the surface convects (gets heated, rises to the surface, cools, and sinks down only to be reheated and continue the cycle) but not the matter trapped in these magnetic fields. It can't sink back down once it cools off, which is why it looks black from Earth. These spots are still 3000 degrees kelvin (essentially Celsius) which is really hot but colder than the surrounding 5800 kelvin surface.
