Have you ever wondered what causes the Auroras in the Northern Hemisphere? Auroras are heavenly flashes of light, that can be seen with the naked eye. Scientists have been studying the auroras for many years. In fact, it is so interesting that scientists have even studied the DNA of dolphins. They have found that these animals can also display aurora.
There has long been a theory by scientists that the Auroras are caused by electrons moving around in the atmosphere. For years, they have been trying to prove if electrons are responsible for creating the light we see. It is believed by scientists that when an electron strikes the phosphor, it excites the atom and creates a light emission.
This theory was first proven in 1950, by James Clerk Maxwell, with the help of his new radio technology. Later, other scientists were able to confirm this concept. In fact, the strength of the electromagnetic waves emitted by atoms can be measured very easily.
The strength of these waves depends on the number of electrons that are excited. When these particles have no electrons to move around, they produce zero light. On the other hand, when there are a lot of electrons in the cloud, they give off more energy. So, researchers have been trying to figure out how these electrons get excited and move around the atmosphere. Over the past few years, various experiments were done. These helped researchers figure out how the atmosphere is created.
One of the experiments done showed that the strongest Auroras are produced during the spring. For years, scientists have been trying to figure out why. They have theorized that there may be a connection between the weather and the appearance of the aurora. If it is windy, there would be more storms, which would show up as more activity in the atmosphere. However, in the spring, there are fewer storms and so more energy in the air, giving off more Auroras.
Another experiment showed that there are a lot of electrons in the ionosphere as the weather warms up. This means that as the temperature rises, more electrons are released to take their place. These electrons travel through the atmosphere and then create the aurora. There is a large concentration of these electrons near the North Pole, which has been the mystery behind the presence of the Aurora Borealis for many years.
It is not a secret anymore that the Auroras we see are formed by electrically charged gases floating in the atmosphere. These particles meet up with air molecules and create a wet and glowing surface. Scientists have also discovered that the particles are sensitive to Earth’s magnetic field. This makes sense since the Earth’s magnetic field also affects the electrons. So, by altering the Earth’s magnetic field, the number of charged gases floating in the air can be decreased and this will lessen the number of electrons in the atmosphere, which will decrease the aurora.
If you want to learn more about this topic, you can visit any science-based website to read all the exciting evidence that has been accumulated over the years. You will also find some interesting articles written for your further education. In the meantime, don’t forget to take advantage of all the amazing research that scientists have performed. They have shown us why the Auroras we see are produced by natural processes, not man made pollutants (or have they).
There have been many theories that have been theorized as to what causes the Auroras. The first theory was that it was caused by solar flares and solar storms. Another theory is that it is caused by a comet or an asteroid hitting the Earth. There have also been a few scientists who have pointed out that the Earth wobbles due to its orbit around the sun and this also leads to the phenomenon.
Based on their evidence, scientists have determined that there is a very strong connection between the Aurora and magnetic fields. It has also been determined that the strongest magnetic fields are found around the North Pole. Some scientists have even pointed out that the North Pole has more magnetic energy than anywhere else in the solar system. Based on this evidence, they have concluded that our magnetism comes from the earth. Not only are we influenced by the earth’s magnetism, but also the sun’s magnetism.
There is so much evidence that backs up these beliefs. If you are still skeptical then I suggest you spend a couple of hours online collecting your own evidence. It does take a bit of effort and time but it is so rewarding when you start to see the evidence for yourself.
