    "body_text": "Researchers have long described a saturation point beyond which stronger solar wind appeared unable to drive proportionally stronger electric currents in Earth's upper atmosphere. A NASA-led team argues that the plateau is an artifact of comparing Earth's response with solar-wind readings taken roughly a million miles upstream, where uncertainty grows before the same plasma reaches the magnetosphere. When the researchers analyzed more than a million measurements collected closer to Earth by missions including MMS and THEMIS, the current response remained approximately linear at the strongest observed inputs. The result does not predict a particular blackout or prove that no physical limit exists, but it removes a reassuring ceiling from a widely used picture of space-weather risk and makes better observations of extreme storms more urgent.",
