Commission B4 Radio Astronomy


Commission B4 brings together scientists and engineers who carry out observational and theoretical research in radioastronomy and who develop and operate the ground and space-based facilities that are used to explore the Universe at radio wavelengths.

The primary purpose of this Commission will be to coordinate the unique role of Radio Astronomy as part of our global multi-wavelength capability in astronomy, taking in consideration the long-term international development of this field.
