According to Metropolis Express, Zhang Baolin, a former meteorite expert at the Beijing Planetarium, said, "From visual observation, this big fireball should be a fireball. But it is actually very difficult to find the exact falling position." The fireball phenomenon is a meteor phenomenon produced when a larger meteoroid falls. The fire phenomenon should occur at an altitude of 12 to 120 kilometers above the ground, and meteoroids will shine in this space. It enters the atmosphere very quickly, and the heat generated by friction will heat the surrounding air to tens of thousands of degrees Celsius. Its surface temperature can reach 4000 degrees Celsius, at which time it will glow. Bright fireballs can illuminate a large area like a moonlit night or even as bright as day. When the meteor trail in the sky is obscured, a dust trail like a smoke column will appear and can last for several hours. Zhang Baolin cited a fireball incident: At around 7:44:13 in the morning on January 15 last year, a fireball flew rapidly from southwest to northeast in Xinjiang. Image source: Metropolis Express Although it lasted only a few seconds, the light was extremely strong, an airburst occurred during the period, and some people heard a thunderous rumbling sound. After the airburst, the fireball's light dims and eventually disappears. Image source: Metropolis Express This incident quickly alarmed many meteorite hunters and meteorite enthusiasts, and they all rushed to the site to visit, but found no useful information. Teacher Zhang introduced that "some people speculated that the fireball should have fallen in the northeast of the Junggar Basin, in the area of Qitai County and Mulei County. Later, the meteorite was found, and the final location was in Shanshan area." Source: Science and Technology Daily, Jimu News, Metropolis Express, etc. |
