Astronomers reported on Thursday that this enormous burst of radio waves stretches twice the width of the Milky Way galaxy, making it the largest discovered at such an early stage in the universe ...

By analyzing the data from Leahy's atlas of double radio-sources and NASA/IPAC Extragalactic Database (NED), Serbian astronomers have explored an X-shaped radio galaxy designated 3C 315. Results of ...

Figure caption, Each region of the electromagnetic (EM) spectrum has a range of wavelengths associated with it. Radio waves have the longest wavelengths and gamma rays have the shortest wavelengths.

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 ...

These Radio wave Observations at the Lunar Surface of the photoElectron Sheath (ROLSES) will permit determination of the photoelectron sheath density from ~0-2 m above the lunar surface, using ...

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 ...
