AM, or amplitude modulation, was the earliest way of sending voice over radio waves. That makes sense because it is easy to modulate a signal and easy to demodulate it, as well. A carbon ...

Astronomers have traced two mysterious fast radio bursts from space to wildly different places, which suggests the phenomenon may originate in diverse ways.

our current theories say a pulsar spinning only once every 18 minutes should not produce radio waves. So we thought our 2022 discovery could point to new and exciting physics – or help explain ...

At the border between infrared and radio waves lie electromagnetic ripples measured in millimeters. They are now made in the laboratory, where they are used to study the properties of atoms and ...

At double the width of our Milky Way galaxy, this jet of radio waves is the biggest ever detected so early in the universe's ...

Here’s everything you need to know. Like all cellular wireless technologies, 5G works through radio waves. Radio waves are essentially electromagnetic waves that radiate a certain number of ...

When astronomers detected the first long-predicted gravitational waves in 2015, it opened a whole new window into the ...

At double the width of our Milky Way galaxy, this jet of radio waves is the biggest ever detected so early in the history of the universe, astronomers reported Thursday. Radio jets like this are ...
