A new type of gravitational antenna will be built in Antarctica. It will capture low-frequency space vibrations that are inaccessible to current detectors, allowing us to hear the cosmic symphony in previously unheard notes.

Earth's internal structure is traditionally studied using seismic methods and gravimetry. But neutrinos—particles that barely interact with matter—offer a fundamentally different, gentle probe. The IceCube collaboration analyzed 10.7 years of muon neutrino observations with energies from 500 GeV to
