Electromagnetic radiation astronomy is a research area focused on observing and interpreting astrophysical phenomena through their emission, absorption, and scattering of electromagnetic radiation across the entire spectrum, from radio waves to gamma rays. It encompasses the development and use of ground-based and space-borne telescopes, detectors, and instrumentation optimized for specific wavelength ranges, along with calibration, data reduction, and spectral, temporal, and imaging analysis techniques. The field integrates radiative transfer, plasma physics, and atomic and molecular processes to infer physical conditions, kinematics, composition, and magnetic fields in cosmic sources, and underpins multiwavelength and multi-messenger studies of the universe.
Up until recently, astronomy was reliant entirely on electromagnetic waves. While that changed with the confirmation of gravitational waves in 2016, astronomers had developed fundamental frameworks in the electromagnetic ...

Astronomers from West Virginia University and elsewhere report the detection of 18 new pulsars using the Arecibo Observatory (AO) as part of the AO 327-MHz Drift Survey. The findings were detailed in a research paper published ...
When astronomers detected the first long-predicted gravitational waves in 2015, it opened a whole new window into the universe. Before that, astronomy depended on observations of light in all its wavelengths.
