Low-frequency radio telescopes

Telescope Name Location Frequency Range Number of Antennas Key Scientific Objectives Notable Features
LOFAR (Low Frequency Array) Primarily Netherlands, with stations across Europe 10–240 MHz ~50 stations Cosmic magnetism, Epoch of Reionization, solar and space weather studies Network of dipole antennas with digital beamforming, wide field of view
MWA (Murchison Widefield Array) Murchison Radio-astronomy Observatory, Western Australia 80–300 MHz 128 tiles (each with 16 dipoles) Epoch of Reionization, solar physics, transient events Precursor to the SKA, large field of view, rapid surveys
NenuFAR (New Extension in Nançay Upgrading LOFAR) Nançay, France 10–85 MHz 1,938 antennas (planned) Exoplanet detection, Cosmic Dawn, pulsars Functions autonomously and as a LOFAR “superstation” for enhanced sensitivity
SKA-Low (Square Kilometre Array – Low Frequency) Murchison Radio-astronomy Observatory, Western Australia 50–350 MHz ~131,072 antennas (planned) Early Universe studies, cosmic magnetism, galaxy evolution World’s largest planned radio telescope, high sensitivity and survey speed
GO-LoW (Great Observatory for Long Wavelengths) Proposed space-based array (L5) 100 kHz–15 MHz Thousands of SmallSats (planned) Exoplanet magnetic fields, interstellar medium Overcomes Earth’s ionospheric limitations, SmallSat constellation interferometry
GMRT (Giant Metrewave Radio Telescope) Pune, India 150–1420 MHz 30 antennas Galactic and extragalactic observations, pulsars, hydrogen mapping Widely used for surveys and studies of hydrogen line emissions
