Although we have never seen it, the Earth’s magnetic field is one of the factors that allow life to thrive on Earth,media reported. It protects us from some of the adverse factors that affect the way stars such as the sun operate, and researchers have been monitoring their state and doing their best to understand what is affecting it.
So when a ripple passes through the Earth’s magnetic field, the researchers initially suspected that the sun was firing something in our direction. To do this, they examined the solar wind — because its changes can cause similar ripples, but found no anomalies. In this case, it seems that the sun is so quiet that scientists can “hear” things they don’t usually hear.
The sun has different cycles. During the high-activity period, the star emits a large number of charged particles. Solar storms are super-explosive stakes made up of such particles that affect the Earth’s communications networks and disrupt satellites and other spacecraft. However, the sun is now in a period of extremely low activity, which may be why researchers were able to detect this new ripple.
The type of ripple found is called continuous pulsation (PC). Although these waves have been observed in the past, they are often difficult to observe because solar activity interacts with the Earth’s magnetic field and produces a lot of noise. The dragonfly disappeared in all activities.
Naturally occurring ripples are easier to see when external forces are low. This particular wave is thought to be related to the particles released by the halo of charged particles formed by the Earth’s own magnetic field. When these particles disengage, they cause a small disturbance to the magnetic field that is never detected during the sun’s high activity.
Scientists already know that the sun’s solar activity will be particularly quiet this time, meaning it may be easier than ever to detect subtle changes in the Earth’s magnetic field. This is a surprise for researchers focused on the inner workings of the Earth, giving new insights into how the Earth’s magnetic field works and giving scientists an idea of what was missing during the sun’s high activity.
