A rare hurricane that attacked the northern pole of the Earth in 2014 was filled with amazing cartoon, and scientists were thought to be a stranger.
According to a new study, this day called “space hurricanes” is usually seen only during large solar storms, despite the sun being abnormally calm on that day, usually only the effects of widespread weather are removed.
The report presented the first detailed analysis of the Eight Eight -Hour Tempests, which was Has first occurred August 20, 2014. Researchers found that it disrupted the GPS signal, shook the earth’s magnetic field, and tied the upper environment to extra electrons.
“Our studies show that space hurricanes can trigger the significant effects of the space weather, even commonly seen as extremely quiet periods,” the lead author of the Study, Sheng Lu, who was published in the Institute of Space Sciences at the University of Shandong, China, and published in his studies. Journal space weather.
A stealthy storm in space
2014 space hurricanes, first Formally described In 2021, the US Army’s DMSPF 17 satellite was initially detected, which oversees space weather conditions. According to new research, after minutes, the European Space Agency’s crowd Bettletite flew from the nearby region, collecting key data, which confirmed the storm structure and size.
Hurricane measured more than 620 miles (1,000 km) diameter and rotated on a polar hat, a high dimensional zone where EarthThe magnetic fields add solar and cosmic particles to the atmosphere. Like its environmental names, the space hurricanes included a quiet center, or “eye”, and rotating spiral arms that were clearly visible in satellite observations. But instead of winds and heavy rains, it threw the rivers of high -energy electrons into the upper environment.
Although they are hidden from the naked eyes, but with the flashing, the spiral shape, the space hurricane can be detected by satellite and sensitive devices on Earth. Orras These storms arise.
In this case, data from several spacecraft and geographical stations in the Arctic of Greenland and Canada showed obstacles to the GPS signal, the magnetic field volatility and high electron density-these sub-satellite navigation, communications and radio translations.
Researchers were allowed to rebuild the storm in extraordinary detail, which was not possible in some decades. Since the late 1960s, researchers were suspected that hurricanes could be available, so far they had a shortage of tools tools to confirm the storms.
“These days, although there were a lot of spacecraft in space, they didn’t have a device that you would really need to understand what’s happening,” John FosterA research scientist from MIT’s Steak Observatory who called back after seeing a similar incident over 50 years ago, said eos. “This event really has a wide variety of things that make up the features that were available in space to see the features of this phenomenon.”
Initially, a rare irregularities are considered, the 2014 space hurricane has helped open the door for further discoveries. Recent follow -up studies have revealed that these storms are not just More frequently than being thought of before But the two are also found in the hemisphere – usually during the summer months and possibly 10 times a year.
Despite the potential barriers to satellite planets and trash pieces in orbit, space hurricanes Don’t be a threat to life on earth.
