A 'Hidden' Solar Outburst Just Exposed a Blind Spot in Space Weather Forecasting A recent discovery by NASA's Europa Clipper spacecraft has revealed a concerning limitation in space weather forecasting: a blind spot that could endanger future crewed missions to deep space.
On December 19, 2024, the probe detected an unusual plasma signal from a coronal mass ejection (CME) that had not been predicted by forecasters on Earth.
The CME was complex and irregularly shaped, with one part heading straight for our planet while another part veered off course.
