Visible light is just one part of the electromagnetic spectrum that astronomers use to study the Universe. The James Webb Space Telescope was built to see infrared light, other space telescopes ...

Marguerite Reardon started as a CNET News reporter in 2004, covering cellphone services, broadband, citywide Wi-Fi, the Net neutrality debate and the consolidation of the phone companies. Your brand ...

Observations with the LOFAR (Low Frequency Array) radio telescope last year showed that first generation Starlink satellites emit unintended radio waves that can hinder astronomical observations. New ...

Associate Professor of Physics Jonathan Pober has spent the past 20 years detecting faint astronomical signals in radio waves that can provide information about the early universe. This task can be ...

Radio observatories like the Green Bank Telescope are in radio quiet zones that protect them from interference. NRAO/AUI/NSF, CC BY Radio telescopes are facing a problem. All satellites, whatever ...

Radio frequency interference (RFI) arises when man-made or natural radio emissions intrude upon the faint celestial signals sought by radio telescopes. As radio astronomy advances towards greater ...

To meet an increased demand for canceling radio frequency (RF) signal interference, L3 has built a system that can do just that and is planning to expand it into a software capability. L3 is already ...

Q: My 2-year-old HP running Windows 11 began locking up intermittently. I had it in a shop twice, and it worked perfectly at the shop. At home, it began locking up after working for several hours. The ...

Amateur radio operators and shortwave listeners have a common enemy: QRM, which is ham-speak for radio frequency interference caused by man-made sources. Indiscriminate, often broadband in nature, and ...

Re “AM radio in your car? Don’t let Congress decide.” by Jeff Jacoby (Opinion, May 31): Electric motors and other electronic equipment in electric vehicles can be a major source of radio frequency ...

Lately I’ve seen a number of discussions about adding a frequency offset to an ATSC 1 signal to reduce interference. The issue came to light when it was discovered that at least one major manufacturer ...
