A signal unlike any other has reached Earth. The 3I/ATLAS project detected a unique transmission using the Fibonacci sequence ...

In 1977, astronomer Jerry Ehman discovered the mysterious “Wow! Signal” — a powerful radio burst from deep space at the hydrogen line frequency. Nearly five decades later, scientists believe the newly ...

When the clock strikes midnight on Dec. 31, it will not only be the end of 2015, it will be the end of medium wave (526.5-1606.5 kHz) broadcasting for Radio France. This will cease the broadcast of ...

FOR many years past, the mode of propagation of radio waves through the ionosphere has been studied intensively by mathematicians, physicists and radio communication engineers. It is now well known ...

When you are capturing audio from a speaker, you are rarely capturing the actual direct output of such a system. There are reflections and artifacts caused by anything and everything in the ...

At high enough flight velocities, the intense heating of the gas generates a plasma layer around the vehicle. The presence of free electrons in the flow field has been known to hinder the transmission ...
