The Sun is now in the quietest phase of
its 11-year activity cycle, the solar minimum - in fact, it has been
unusually quiet this year - with over 200 days so far with no observed
sunspots. The solar wind has also dropped to its lowest levels in 50
years. Scientists are unsure of the significance of this unusual calm,
but are continually monitoring our closest star with an array of
telescopes and satellites. Seen below are some recent images of the Sun
in more active times.
