We witness a new scientific discovery every day on the planet we live in. Finally, scientists announced that they have detected a new type of magnetic wave passing through the Earth’s outer core.
Using information from the European Space Agency’s Swarm satellite mission, experts have discovered a new type of magnetic wave that sweeps Earth’s outer core every seven years. The finding from ESA’s data shows that it also opens a window to a world we will never see.
Detected by ESA’s Swarm satellites
Swarm satellites, which enable the movement of magnetic fields on Earth to be followed from space, come from the ocean, crust, ionosphere and manetosphere. measuring signals. By analyzing this collected data, experts discover new mysteries about many of the Earth’s natural processes.
According to experts, the newly detected magnetic wave oscillates every seven years, spreading westward for up to 1500 kilometers. “Geophysicists have long theorized about the existence of such waves, but they were thought to occur on much longer time scales than our research shows,” said Nicolas Gillet of the Université Grenoble Alpes. Also, experts called this wave “Magneto-Coriolis” waves.
For those who don’t know, Earth’s magnetic field is likened to a gigantic balloon carried by strong winds, escaping cosmic radiation attacks and the Sun’s gravity. Some movements in magnetic waves; Solar storms are said to damage communications networks, navigation systems and satellites.
