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 ...

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

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 ...

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 ...

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

Fast radio bursts (FRBs) are brief emissions of radio waves, lasting a fraction of a second but with as much energy as the ...

Last summer, astronomer Calvin Leung was excited to analyze data from a newly built radio telescope. His goal was to pinpoint ...

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