Astronomers discover new supernova remnant

Astronomers from Curtin University in Australia and elsewhere report the detection of a new supernova remnant (SNR) located some 3,300 light years away. The newfound SNR, designated G321.3-3.9, has an elliptical shape and ...

NASA's new experimental antenna tracks deep space laser

An experimental antenna has received both radio frequency and near-infrared laser signals from NASA's Psyche spacecraft as it travels through deep space. This shows it's possible for the giant dish antennas of NASA's Deep ...

NASA to study effects of radio noise on lunar science

In February 2024, Intuitive Machines' IM-1 mission will launch to the moon's South Polar region, as part of NASA's Commercial Lunar Payload Services (CLPS) initiative. This mission is part of the CLPS ongoing effort to bring ...

Radio frequency

Radio frequency (RF) is a frequency or rate of oscillation within the range of about 3 Hz to 300 GHz. This range corresponds to frequency of alternating current electrical signals used to produce and detect radio waves. Since most of this range is beyond the vibration rate that most mechanical systems can respond to, RF usually refers to oscillations in electrical circuits.
