Cosmic burst probes Milky Way"s halo
Astronomers have used an intense burst of radio waves originating from a nearby galaxy to inspect the halo of gas cocooning our own Milky Way galaxy. The scientists studied the way that the light of the so-called fast radio burst, or FRB, was dispers.....»»
Airport 5G problem: Airlines now get until next year to fix it
The airport 5G problem – where some planes with older or faulty radio altimeters could be confused by strong 5G signals – has resulted in a further compromise. Carriers wanted airlines to have to promptly bring their equipment up-to-date, while.....»»

An experiment to bounce a radio signal off an asteroid on Dec. 27 will serve as a test for probing a larger asteroid that in 2029 will pass closer to Earth than the many geostationary satellites that orbit our planet......»»
Astronomers scanned 12 planets for alien signals while they were in front of their stars
The Robert C. Byrd Green Bank Telescope (GBT), part of the Green Bank Observatory in West Virginia, is the world's premiere single-dish radio telescope. Between its 100-meter dish (328-foot), unblocked aperture, and excellent surface accuracy, the GB.....»»
Single-pulse behavior of rotating radio transient PSR J0628+0909 explored with FAST
Using the Five-hundred-meter Aperture Spherical radio Telescope (FAST), Chinese astronomers have inspected single-pulse behavior of a rotating radio transient (RRAT) known as PSR J0628+0909. Results of the study, published November 22 in Monthly Noti.....»»
High-speed, high-sensitivity terahertz detection using graphene transistor
On the electromagnetic spectrum, which comprises everything from radio waves to X-rays and gamma rays, there exists a deadzone where conventional electronic devices can hardly operate. This deadzone is occupied by terahertz waves......»»
