Obiter Hit By A Coronal Mass Ejection

The sun-exploring Solar Orbiter spacecraft came face to face with a massive eruption of plasma from the sun, just ahead of a pivotal flyby of Venus.


An enormous coronal mass ejection (CME), a burst of charged particles from the sun's upper atmosphere, the corona, shot out from the sun on Aug. 30 in the direction of Venus. Shortly after that, the bubble of solar material reached Solar Orbiter, which was just preparing for its latest orbital flyby of the second planet of the solar system.

Fortunately, the ESA-NASA observatory is designed to measure the very kind of violent outburst it just encountered and thus could withstand the solar assault with ease.

The spacecraft carries 10 science instruments to observe the sun's surface and collect data on CMEs, the solar wind and the sun’s magnetic field. Some of these instruments were turned off during the close approach to Venus, due to the potential risk from sunlight bouncing off the highly reflective Venusian atmosphere, ESA said in a statement.  READ MORE...
