SYDNEY, Oct. 11 (Xinhua) -- Australian researchers on Thursday said they have detected a record number of mysterious radio waves from space, including the closest and fastest of such bursts ever found, that may help shed more light on the matter between galaxies. "We've found 20 fast radio...

Fast radio bursts, or FRBs, are brief, powerful pulses of radio waves detected from space. Some can last up to three seconds long, while others appear and disappear in a fraction of a millisecond. However, their origin is a ...

While conventional optical methods for tracking space debris are only possible at night and without cloud cover, radio waves can be used at all times of day and regardless of weather. By utilizing FM signals which are already there, the method saves money and acts as an early warning system ...
Now, radio waves can be detected.For example, very low frequency radio waves can be detected with a special type of radio receiver called a very low frequency, radio, or VLF radio. Which can pick up radio waves with very low frequencies , from 3 to 30 kilohertz, which aren't really pi...
Female Student: Oh, so our radio waves here, on Earth, interfere with the waves from space?Male Professor: Yes, signals from radios, cell phones, TV stations, remote controls—you name it.All these things cause interference.We don’t think about that as often as we think about light ...
These sunspot radio bursts also have other characteristics – such as their spectra (or intensity at different wavelengths) and their polarization (the angle or direction of the radio waves) – that are much more like radio emissions produced in the polar regions of Earth and other planets with...
