Antarctic Offworld Analog: Aurora Australis Over Concordia Station
This dazzling light show appears when charged particles from the Sun are guided by Earth’s magnetic field towards the polar regions, where they collide with gases in the upper atmosphere […]
![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)
