Humans change every environment we inhabit on Earth, building cities, clearing forests, growing crops, and living in even the most remote parts of our world.
But now we have evidence that we also affect the vacuum of space around us.
According to new findings, a type of radio communication actually produces something like a bubble of radiation protection around our planet. The study also includes insights from research into how Cold War-era nuclear tests changed the space environment around Earth.
“A number of experiments and observations have figured out that, under the right conditions, radio communications signals in the VLF [very low frequency] frequency range can in fact affect the properties of the high-energy radiation environment around the Earth,” Phil Erickson, a co-author of the new study appearing the journal Space Science Reviews, said in a statement.
