We have accidentally created a barrier around our planet , and while it might not be a futuristic force field , it is still damn nerveless .
NASA researchers have light upon that certain tuner communications , known as VLF ( very low-spirited absolute frequency ) , are capable of interact with particles in space , strike them in certain directions . We know we can affect the infinite weather around our major planet , but this find might lead to ways that we could actually manipulate it . The discipline is published inSpace Science Reviews .
“ A act of experiments and observations have figured out that , under the right condition , radio communication signaling in the VLF absolute frequency range can in fact affect the properties of the high-pitched - muscularity radiation surroundings around the dry land , ” suppose co - author Phil Erickson , assistant director at the MIT Haystack Observatory , in astatement .
The subject area is a comprehensive review on the human effect around our satellite . It discusses the impact of gamy - ALT atomic tryout , chemical substance release experiments , and in high spirits - frequency wave heating in the ionosphere . The recap goes into the physics behind all those issue and uncover the latest analysis of the VLF interaction .
Earth is surrounded by regions filled with charge particle , known as the Van Allen Belts . It was traditionally assumed that there were two such regions , but it turns out that the picture is alot more complex . They are a consequence of Earth ’s magnetised field and represent as an almost dense barrier , keep the most industrious negatron from reach out our planet .
Using data fromNASA ’s Van Allen Probe , the researchers have discovered that the VLF - induce house of cards extends up to the interior edge of the Van Allen Belt and not further . The team speculate that the VLF bubble is pushing the Van Allen Belt outwards .
This idea is strengthened by data from the sixties , which present the Van Allen Belt to be much close to our planet than it currently is . Back then , VLF transmissions were a fortune more limited , which could explicate the difference . The research worker hypothecate that if there were no VLF , the boundary would adulterate closer to Earth .
The team suggests that with further written report , we might discover if we can remove excess particles from lower Earth ’s orbit . This might help during extreme space atmospheric condition events that might damage planet and other instruments .
There are already design in place to examine VLF from high in the atmospheric state to see on the nose what we can achieve with them .
