The whole sun, showing sunspot groups

Sunspots follow an 11-year cycle, building up numbers to a maximum and then they become fewer until there are none visible at the solar minimum.
Although we are now past tha latest minimum, hardly any sunspots have been seen, which has caused debate among astronomers as to why this is so. |

A staggering view of Saturn, not taken from the Hubble Space Telescope, but by Simon Kidd from his back garden in Welwyn!

For a short time, Jupiter and Neptune were close enough in the sky to be seen in the same field of view in a tlesecope. Dale captured this amazingly rare event.
