The earth is undoubtedly the most magical planet in the solar system. It is absolutely a miracle that not only life has evolved on the surface of the earth, but also highly intelligent human beings have been born. The sky above the earth is a magical area. It looks extremely empty here. There seems to be no other objects except air and clouds. However, various natural wonders appear frequently, which makes people never tire of seeing them, such as the meteor shower that appears as scheduled every year, the northern lights that are frequently staged, the rare red elves, mysterious spherical lightning and so on.

Many natural wonders seem very mysterious, but they have been revealed by scientists. However, some natural wonders have not been solved so far, such as ball lightning and Steve, and the reasons for their formation are still a mystery. Recently, there have been many natural wonders on the earth. There are "three suns" in the sky of Xuanwu Gate in Xicheng District of Beijing, a pillar of fire in the sky of West Virginia in Siberia, and dozens of "pillars" perpendicular to the earth suddenly appear in the midnight sky. An imaginary lake appeared in the sky of Kumutage Desert in the hinterland of Xinjiang Library.

Now, a new report published in Nature describes another natural wonder-the cone-shaped blue jets, which was not discovered by us in the past because it only appeared above the dense thunderstorm clouds. It was not until the human space station appeared in low earth orbit that scientists inadvertently discovered a new phenomenon. 2065438+On February 26th, 2009, when the International Space Station passed 400km over the Pacific Ocean, the camera captured a cone-shaped blue jets over the thunderstorm near Nauru Island. A bright cone-shaped blue light appears from above the thunderstorm cloud, which is even rarer than the red elf.

So far, the camera of the International Space Station has recorded five intense blue flashes, each lasting about 10 to 20 milliseconds. The lens shows that the cone-shaped blue jets starts from above the thunderstorm cloud, starts with a narrow cone, and then spreads upward, extending to the stratosphere at a height of 50 kilometers. According to scientists, this is a kind of lightning that is different from ordinary lightning. When the upper part of the cloud is positively charged and the air above the cloud is negatively charged, they may interact to produce a cone-shaped blue jets, so this phenomenon should be the result of air "electrical breakdown", that is, dozens of kilometers of air is electrically broken.

According to the report, on the contrary, it is a natural phenomenon that charges are exchanged and temporarily balanced in the cloud, releasing static electricity. Known by scientists as "elves", it is similar to the phenomenon of red elves. It represents the light emission and extremely low frequency disturbance caused by electromagnetic pulse source, which is a kind of light emission that expands rapidly in the ionosphere. Because we know very little about it now, and the cone-shaped blue jets rarely appears, it is still unknown how high it can extend above the clouds, so researchers need to do further research on it.
