Successfully demonstrates the origin of northern lights – June 8 CNNReport on the success of American scientists in proving the origin theory of the Aurora Boralis or Northern Lights phenomenon.
Aurora Borellis is a phenomenon of colorful light in the sky of the Northern Hemisphere. Although scientists have theorized the origin of such amazing phenomena. But this has not been proven for centuries.
Such work is the work of a team of physicists from the University of Iowa in the United States. The northern lights are caused by electromagnetic waves. Strong electromagnetic waves in geomagnetic storms
Studies indicate that this phenomenon is also known as alphen waves, a type of wave formation in plasma physics.
Alphen waves cause electrons to move faster with one direction towards the earth. As the particles move, they emit release energy in the form of light waves that can be seen in different colors. Each color represents a wave of light with different energy levels. Change the color of the sky known as Aurora Borellis
Greg Howes, an assistant professor at the University of Iowa School of Astrophysics, said that electrons oscillate faster as a result of the alpine wave electric field.
“Imagine a surfer. Electron particles are chalkboards. That wave was the Alphen wave. The symbol of the surfer wave moved up and fell down again. that’s all.”
The theory has been put forward by Russian physicist Lev Davydovich Lando since 1946. The electron theory of “surfing” or landing damping (landing vibrations) in electric fields is a major contribution to plasma physics. His work on quantum fluid theory led to him winning the 1962 Nobel Prize in Physics.
Experiment with northern lights
The report states that scientists have long understood the phenomenon of northern lights, but this latest experiment is only the first successful simulation of the phenomenon in the large plasma instrument laboratory at the Institute of Basic Plasma Sciences. California State University Los Angeles Campus or UCLA
The team used a 20-meter laboratory to simulate the Earth’s magnetic field. This creates a similar plasma near the Earth. Then, using an antenna that emits an alpha wave, the electron particles are detected to be compatible with LANA vibrations. The results of these experiments excited physicists around the world.
Although such experiments did not create the phenomenon of northern lights in the laboratory. But computer simulation of various instruments found that these electron particles could reach speeds of up to 72,420,480 kilometers per hour (45 million miles per hour), creating an aurora.
Shri. Patrick Cohen, scientist at the Solar Physics Unit. He said the results of the US National Aeronautics and Space Administration (or NASA) (heliophysics) were very exciting for them. Because no more such experiments are coming out. This proves theories and models of space conditions, mainly because space is too vast to be simulated in a laboratory.
Cohen said the results could be very useful in understanding the state of space. This is because this behavior is common in the solar system. Including a space forecasting system focused on NASA development.
There is still a long way to go
The results obtained will help prove the theory of the phenomenon of northern lights. Howes said. However, predicting the intensity of the Earth’s magnetic storm by observing the Sun’s characteristics using space probes remains an extremely challenging task.
We can know the relationship between electrons that are subjected to alphan waves. The waves were tens of thousands of miles above the earth. The next step is to understand how to predict the magnitude of the alphen wave using orbital investigation, ”Assoc. Prof. Howes said.
