Sun in different filters

To the unaided eye, space appears to be a vast, dark void, and the Sun a tranquil sphere of light. But in fact, space is not empty because Earth’s orbit lies within the atmosphere of our dynamic Sun. Our Solar System has the cosmic equivalent of wind, clouds, storms, and hurricanes called space weather. It’s one of the consequences of living with a star.
