SOHO (ESA & NASA)
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.
