Radio astronomy is a branch of astronomy that studies celestial objects and phenomena through the detection of radio waves emitted by stars, galaxies, and other cosmic sources. Using advanced radio telescopes, scientists explore the universe beyond visible light, uncovering insights into black holes, pulsars, interstellar gases, and cosmic microwave background radiation. Radio astronomy plays a pivotal role in understanding the universe's origin, structure, and dynamics, revealing the hidden and energetic processes shaping the cosmos.
