A Lucky Spacecraft Alignment Has Recorded a Huge, Evolving Solar Eruption – ScienceAlert

Our Sun isn’t exactly a serene ball of scorching hot plasma. In fact, it belches out colossal eruptions on a somewhat frequent basis; such coronal mass ejections, when directed at Earth, are the cause of geomagnetic storms.
From near-Earth space, we can measure them pretty well with satellites and other spacecraft. But in 1998 something incredibly fortuitous occurred. Not only was a spacecraft in near-Earth space able to measure a coronal mass ejection (CME), another spacecraft out past Mars lined…
