In the news
The article uses 'magnetospheric' to distinguish between the actual physical processes occurring in Earth's magnetic environment and the statistical artifacts that previously made it appear as if that environment had a set limit to its response.
For decades, scientists thought Earth’s geomagnetic response would hit a ceiling as solar storms intensified. A NASA-led Nature study published in July 2026 found that apparent limit was probably a measurement artefact: once the uncertainty was corrected,
