Oneto reported in early 2021 that a giant bubble of VLF radio frequencies - entirely created by human activities - is not only surrounding the Earth, but is creating weather-like effects in space.  According to NASA, the bubble was first detected in 2017, and is the result of very low-frequency radio communications, often used for coded or long-distance messaging - such as contacting submarines deep underwater. These frequencies have been "leaking" into space, and have created a barrier of sorts around Earth.

As turns out, this giant bubble is keeping charged, radioactive particles from entering Earth's atmosphere. Various nuclear blasts over the years have resulted in belts of radioactivity around Earth, which this barrier has pushed further away than they were in the 1960s. “A number of experiments and observations have figured out that, under the right conditions, radio communications signals in the VLF frequency range can in fact affect the properties of the high-energy radiation environment around the Earth,” Phil Erickson, assistant director at the MIT Haystack Observatory, said, according to NASA. 

In effect, VLF frequencies are creating human-induced 'space weather'. Unfortunately, according to a new article from Science Alert, the barrier doesn't solve the problem with the radioactive particles damaging Earth's satellites.

NASA says that tests are underway to see if VLF transmissions can be used to remove the excess radiation surrounding Earth.
