NASA Just Found the Sun's Secret Warning Before Massive Solar Outbursts

This discovery could help NASA and other organizations protect astronauts, satellites, and technologies on the ground from the potentially harmful effects of space weather.
The European Space Agency's (ESA) groundbreaking Prova-3 mission has successfully begun its formation flight phase, with two satellites now maintaining a precise 150-metre separation in orbit. This precision will enable the creation of artificial solar eclipses, providing unprecedented views of the Sun's corona. Credit: ESA-P. Carril

"These interactions between the Sun's coronal mass ejections and interplanetary dust were theorized twenty years ago, but were not observed until the Parker Solar Probe saw that the coronal ejection acts like a vacuum cleaner.

These dark spots on the Sun, visible in ultraviolet light, are called coronal holes and are areas where fast solar wind bursts out into space. By chance, they managed to take a photo that looked like the sun was smiling.
