The US Department of Energy's SLAC National Accelerator Laboratory has developed a compact antenna that can transmit radio signals not only over long distances through the air, but also underwater, ...

NASA is launching a suborbital sounding rocket to study how radio waves escaping the Earth's ionosphere may be affecting orbital satellites. Scheduled for launch from the Wallops Island Flight ...

Breakthroughs, discoveries, and DIY tips sent six days a week. Terms of Service and Privacy Policy. When the Navy wants to send a message to an underwater submarine ...

A group of five Talawanda high school seniors are building a VLF space antenna to monitor changes in ion activity in the atmosphere during the solar eclipse of August 21. Energy from the sun creates a ...

Earth is surrounded by a radio field caused by very low-frequency waves. This field pushes away the Van Allen Belts, a radiation swim-floaty that surrounds Earth's middle. Van Allen radiation hinders ...

NASA’s Van Allen Probes have discovered some strange radio wave activity in the space around Earth. On Wednesday, NASA Goddard Space Center announced that the two probes had helped scientists identify ...

When it comes to the impact humans have had on the Earth, the evidence spans much further than just the surface, but also the outer space surrounding our lovely planet. Not only have we sent so much ...

If you need to generate a radio frequency electrical signal, you will make some form of electronic oscillator. We’ll probably all be used to oscillators using transistors, tubes, logic gates or a host ...

In California, a retired electrical engineer has revived an out-of-production sonar device that uses very low frequency, or VLF, radio waves to locate underground water, and, as recently as Feb. 15, ...

Scientists say NASA's Van Allen Probes have spotted a man- made barrier around the Earth that prevents high-energy space radiation from reaching the planet Exciting, sharp and clear analysis of the ...
