The next ‘unthinkable’ – global disruption from a solar storm
... on Earth is the Sun. It produces bursts of electromagnetic radiation (called flares) and eruptions of material known as coronal mass ejections (CMEs), accompanied by solar energetic particles (SEPs). Because of the interaction of CMEs with the Earth...

Parker Solar Probe reveals major new insights on the Sun
... Space weather forecasting will need to account for these flows if we are going to be able to predict whether a coronal mass ejection will strike Earth, or astronauts heading to the moon or Mars," Kasper said. Meanwhile, the probe’s FIELDS instrument...
