New radio receiver opens wider window to radio universe

Researchers have used the latest wireless technology to develop a new radio receiver for astronomy. The receiver is capable of capturing radio waves at frequencies over a range several times wider than conventional ones, ...

Method uses radio signals to image hidden and speeding objects

Researchers at the National Institute of Standards and Technology (NIST) and Wavsens LLC have developed a method for using radio signals to create real-time images and videos of hidden and moving objects, which could help ...

Unique terahertz microscope can be operated remotely

With a wave length of about half a millimeter, terahertz radiation fills the gap between visible light and radio waves. This radiation lends itself very well to the in-depth measurement of the electrical properties of new ...

NASA rocket mission studying escaping radio waves

A NASA rocket mission, launching May 26, 2021, will study radio waves that escape through the Earth's ionosphere impacting the environment surrounding GPS and geosynchronous satellites, such as those for weather monitoring ...

Greenhouse gases are shrinking the stratosphere

An international team of climate scientists has found evidence showing that human-created greenhouse gases have led to a shrinking stratosphere. In their paper published in the journal Environmental Research Letters, the ...
