Radio astronomy - Wikipedia
Radio astronomy is a subfield of astronomy that studies celestial objects at radio frequencies. The first detection of radio waves from an astronomical object was in 1933, when Karl Jansky at Bell Telephone Laboratories reported radiation coming from the Milky Way.
radio and radar astronomy - Encyclopedia Britannica
Radio and radar astronomy, study of celestial bodies by examination of the radio-frequency energy they emit or reflect. Radio waves penetrate much of the gas and dust in space, as well as the clouds of planetary atmospheres, and pass through Earth’s atmosphere with little distortion.
The Science of Radio Astronomy
Radio astronomers study emissions from gas giant planets, blasts from the hearts of galaxies, or even precisely ticking signals from a dying star. Today, radio astronomy is a major branch of astronomy and reveals otherwise-hidden characteristics of everything in the …

MIT scientists pin down the origins of a fast radio burst
2025年1月1日 · The radio telescope array comprises four large, stationary receivers, each shaped like a half-pipe, that are tuned to detect radio emissions within a range that is highly sensitive to fast radio bursts. Since 2020, CHIME has detected thousands of FRBs from all over the universe. While scientists generally agree that the bursts arise from ...
