NASA has recently discovered that humans influenced not only the environment on Earth, but also that in the outer space. They found an electron bubble which surrounds our planet. It seems like it formed as a direct cause of our activity on Earth.
So far, we have thought that certain man-made actions had an impact on our ecosystems. Now, the effect of these activities has expanded and reached beyond the atmosphere, into space. NASA declared that the Van Allen Probe detected this peculiar bubble around Earth.
Communication waves formed a protective bubble around Earth
They explained this was a direct effect of VLF, representing some type of communication waves. These are used by stations on the ground to reach submarines or other remote bases and send messages to them. Now, these waves have extended into space.
After performing several experiments, scientists discovered that, under certain conditions, VLF waves might have an impact on the radiation surrounding Earth. Also, they saw how the outer edge of this protective bubble corresponds to the inner layer of radiation of the Van Allen Probe.
Less radiation now reaches our planet
Therefore, Phil Erickson, scientists at the MIT Haystack Observatory, explained the conclusion they reached. It seems that this bubble is protecting our planet from the extreme radiation issued by particles in space.
Dan Baker, Director of the Laboratory for Atmospheric and Space Physics, University of Colorado, admitted that the radiation would have gotten closer to Earth if the impenetrable VLF bubble was not there. In fact, images from 1960s prove that the radiation coming from Van Allen was much closer to our planet than it is now.
Scientists can use this knowledge to know how to protect satellites from extreme radiation in space. Also, they can learn how to use VLF waves to keep all excessive radiation away from the environment surrounding Earth.
