SUMMARY
The longest wavelength currently observable in radio astronomy is in the extremely low frequency (ELF) range, which can extend up to 100 kilometers. Instruments capable of detecting these wavelengths include ground-based observatories and space missions designed for low-frequency radio observations. Future projects may explore wavelengths beyond current capabilities, potentially utilizing advanced technologies or extraterrestrial platforms. Theoretical discussions suggest that wavelengths longer than 100 kilometers could be feasible with future advancements.
