![Maximum predicted emission frequency and radio flux density for known exoplanets (triangle symbols; data from [8]). The uncertainties on the predictions are estimated to one order of magnitude for the flux density and a factor of 2-3 for the emission frequency12. The sensitivities for the ground-based (UTR-2, LOFAR, NenuFAR, SKA-Low, VLA, GMRT) and space-based (FARSIDE, LCRT, FARVIEW ) radio telescopes are labeled (for 10 min of integration time and a bandwidth of 24 MHz). The FARVIEW and LCRT sensitivity curves are taken from [19] and [2], respectively. The LuSEE-Night sensitivity curve is averaged over the entire two-year mission and includes post-processing using a LombScargle periodogram (see text for details). The possible detection of τ Boo b from LOFAR23 is shown as a red star. This figure is adapted from [9]. -- astro-ph.IM](https://i0.wp.com/astrobiology.com/wp-content/uploads/2025/08/Studying-Exoplanets-in.png?resize=1200%2C720&ssl=1)
Exoplanets with and without a magnetic field are predicted to form, behave, and evolve very differently.

Can A Convecting Magma Ocean Offer A Solution To The Puzzling Case Of Core Convection In Early Earth?
Convective flow in Earth’s iron-rich liquid core drives self-sustained dynamo action, generating Earth’s magnetic field, which is strongest among all terrestrial planets of the solar system.
