A massive human-made barrier has been detected by NASA space probes. The barrier surrounds the Earth, and tests have confirmed that it's affecting space weather.
Human activity has been influencing activities in space and Earth as well. However, the huge bubble that we created out in space is working in our favor.
Space probes were launched by NASA, back in 2012, to work in cycles with each other as they flew through Earth’s Van Allen Belts at speeds of around 3,200 km/h (2,000 mph).
Earth is surrounded by two such radiation belts and a temporary third one. The inner belt stretches from around 640 to 9,600 km (400 to 6,000 miles) above Earth's surface, while the outer belt occupies an altitude of roughly 13,500 to 58,000 km (8,400 to 36,000 miles).
The Van Allen Probes recently detected something strange as they monitored the activity of charged particles caught within Earth's magnetic field. The solar discharges were being kept at a distance by a low-frequency barrier.
After conducting investigations, researchers found out that the barrier had been actively pushing the Van Allen Belts away from Earth over the past few decades, and now the lower limits of the radiation streams are further away from us than they were in the 1960s.
The Very Low Frequency (VLF) radio communications have become more common compared to the 60s. NASA has confirmed that it has the capability to influence how and where certain particles in space move.
Anthropogenic space weather has been greatly empowered by VLF. A team member from the MIT Haystack Observatory in Massachusetts, Phil Erickson, said that several 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.
The majority of the military operations, scientific, and engineering fields rely on the VLF signals. Frequencies between 3 and 30 kilohertz are far too weak to carry audio transmissions, but they're perfect for broadcasting coded messages across long distances or deep underwater.
The most prevalent use of VLF signals is to communicate with deep-sea submarines. However, their large wavelengths can diffract around large obstacles such as mountain ranges, they're also used to achieve transmissions across tricky terrain.
