CME – Coronal mass ejection – Eruptions on the Sun

CME – Coronal mass ejection – Every second the Sun emits around two million tons of particulate matter – or at least that’s usually the case. In the atmosphere, however, sometimes there are enormous eruptions from the corona (Coronal Mass Eruptions, CME). These types of hurricanes are among the most spectacular phenomena in our part universe . In the process, the Sun loses much more weight than usual. The speed of winds reaches even 10 million / h. CME is a cloud of gas built of electrically charged particles (physicists call it plasma gas). Plasma hurricanes can reach Earth and call the so-called geomagnetic storms that affect electronic devices, causing short circuits and equipment damage.

It is impossible to predict how dangerous it can be for satellites. The Internet and computer-controlled objects, such as nuclear power plants. The last really strong solar storm took place in the telegraph age, i.e. long before the appearance of PCs. Although astronomers are constantly observing the behavior of the Sun, they can anticipate it only slightly ahead of time. This means that in the future we will have at least 24 hours to disable all sensitive systems (even those in nuclear power plants) and secure computers. But geomagnetic storms are not the only problem facing us by the most important star …
