Astronomers have identified the source of strange radio flashes: a binary system containing a white dwarf, the remnant of a ...

By analyzing the data from Leahy's atlas of double radio-sources and NASA/IPAC Extragalactic Database (NED), Serbian ...

A mysterious and powerful burst of radio waves reached Earth after traveling through space for 8 billion years dubbed FRB ...

Scientists have gotten the best-ever view of 'space tornadoes' howling near the Milky Way's black hole. The cosmic twisters ...

The black hole examined by the team is no small cosmic object. It is more than a billion times the mass of our Sun. Despite ...

Electromagnetic radiation is the general term for the more familiar light and radio waves, but also includes gamma rays, x rays, ultraviolet rays, and infrared. All of these forms of electromagnetic ...

So, instead of using ultrasound, radio waves are used as they travel at 300,000,000 m/s. It works in the same way as sonar but with radio waves in place of ultrasound. A short pulse of radio waves ...

Different types of electromagnetic wave have different uses and dangers. Radio waves are used for sending radio and television signals. They are also used to control radio-controlled toys ...

Back to our radio signal. The electrons in our wire are moving, but not in one direction. These electrons are moving back and forth. Actually, the wave displayed in the activity is a ...

The first steps toward inventing radio involved discovering electromagnetic waves and their potential. Hans Christian Oersted was the first to proclaim, in 1820, that a magnetic field is created ...

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 ...
