NASA | First Sightings of How a CME Forms

The video discusses coronal mass ejections (CMEs) and their potential threats to technology. It highlights NASA's Solar Dynamics Observatory (SDO) discoveries, particularly in observing flux ropes, which are crucial in understanding CMEs. The challenges of detecting these phenomena due to Earth's atmosphere are addressed, emphasizing the need for space-based telescopes. A case study of a CME event on July 19th, 2012, provides direct evidence of flux rope formation before ejection. The use of 3D imaging from different spacecraft angles offers new insights, suggesting deviations from existing models. The research opens avenues for future studies and practical applications, potentially serving as an early warning system for CMEs.
