Just a week later, on October 21, there will be a solar Eclipse, which will last more than two minutes and will be of record length. To see his people from 14 us States. The American space Agency NASA reported that the sinking of the Land in darkness is not the only and not the most interesting to scientists is the effect of the Eclipse. Reportedly, the professionals in this day will pay attention primarily to the disappearance of the powerful ultraviolet radiation.
Ultraviolet radiation that reaches the Earth from the Sun, has on our planet a significant impact and, in particular, is the reason for the existence of the ionosphere is a very thin upper layer of the atmosphere saturated with ions and free electrons. It is situated at an altitude of 70 kilometers above the Earth’s surface. The study of this part of the atmosphere involves large numbers of scientists, and these studies are considered very important for understanding much of what is happening on Earth processes. The ionosphere reacts to the change of day and night, and to modify space weather, becoming thinner or thicker.
Solar Eclipse, according to representatives of NASA, is an experiment to study the ionosphere, which gives the nature itself — the moon’s shadow will allow you to figure out exactly how it responds to sudden switch between “day” and “night” condition. To determine this, experts plan to use 11 ground-based telescopes, located on the territory of the United States of America.
The last time a solar Eclipse over the United States similar to that which will happen in a week, it was recorded almost a century ago, on 8 June 1918. This time in different periods in complete darkness plunge the States of Oregon, Idaho, Wyoming, Nebraska, Kansas, Missouri, Illinois, Kentucky, Tennessee, North Carolina, Georgia, and South Carolina. The total Eclipse will last 2 minutes and 41 seconds. The inhabitants of the world who have access to the Internet will be able to observe a rare astronomical phenomenon in the online.
