"NASA and ESA Collaborate to Solve Sun's Hottest Mystery"

NASA's Parker Solar Probe, the closest spacecraft to the sun, has become the first to fly through a coronal mass ejection (CME) from the sun, capturing the event with its Wide-field Imager for Solar Probe (WISPR) instrument. The probe spent two days within the CME, which contained billions of tons of plasma, while just 5.7 million miles from the solar surface. CMEs are powerful eruptions of plasma and magnetic field from the sun that can cause geomagnetic storms on Earth, leading to aurora displays and potential damage to satellites and communication systems. The event Parker flew through was on the far side of the sun and not directed at Earth.
