Lighter auroras
01/09/2008 | Elhuyar
The Auroras are caused by a series of explosions that take place in the Earth's magnetic field, as reported by NASA's THEMIS satellite set. These explosions are produced by the solar wind (jet of charged particles coming out of the Sun) modifying the shape of the Earth's magnetic field, that is, extending more and more the zone not oriented to the Sun. Suddenly, as it happens when we have too much a rubber band, the magnetic field is released and it surrounds the Earth again. In this form change occurs a violent explosion and a great release of energy. This energy excites the atmospheric gas molecules. The auroras are luminous waves emitted by the gas molecules excited by releasing the received energy.
