What other type of weather besides what happens on the sun occurs in space?
Space weather is caused only by the sun and the solar wind, as described below: The weather in space comes from the sun. The sun’s atmosphere is very hot, millions of degrees, and is constantly blown away from the sun. This wind is called the solar wind. It can be very fast or very slow, very dense or not very dense. The very fast, very dense solar wind has the most effect on the planets. Space weather is term which generally means the effect of the solar wind on the planets and the regions around the planets. For example, if a large solar flare (bright spot) occurs on the sun, the flare is like an explosion on the sun and pushes even more of the solar atmosphere into the solar wind. If that part of the solar wind strikes the earth, it causes changes on the earth and in space above the earth. For example, auroras are caused in the high latitudes of the earth. At the same time huge currents (one million amperes or more!) are set up in the ionosphere above the aurora. These currents caus
