UNITED STATES – One of the most beautiful things in the world is being able to see an aurora. It has caught everyone’s attention, but in turn these phenomena keep an incredible amount of secrets. For this reason, a scientific team from the University of Iowa discovered a new feature after analyzing a video recorded almost 20 years ago, which generated great shock and arduous study. This atmospheric light show took place on March 15, 2002 in the town of Churchill, Canada. The clip shows how a diffuse section of the aurora quickly lights up, then disappears and, to everyone’s amazement, suddenly reappears after a few seconds. This phenomenon has already been called “diffuse auroral air currents” and has never been studied. For this reason, scientist David Knudsen was commissioned to capture this video a little over two decades ago. Also, he recalled that at that time the sky appeared to be in total darkness and with a special camera he was able to capture the exact moment of the low level light. In this way, the University of Iowa member detailed how things turned out and his undeniable astonishment. “When an area was lit and faded, the diffused dawn in the background was blurry. It’s gone. There was a hole in the diffuse dawn. And then that hole would fill up again after about half a minute. I’ve never seen anything like it, ”Knudsen revealed. In addition, it was stressed the importance of continuing to do the relevant studies to learn more about this incredible phenomenon. On the other hand, it should be noted that auroras occur when charged particles from the Sun interact with the Earth’s magnetic field. So, the moment some of these particles fall on the planet, the energy that is released (in a collision) generates this light from the gases in the Earth’s atmosphere, which gives rise to these beautiful scenarios.
