Summer Solstice from the space. This NASA image is acquired on June 21, 2011.
On the “summer solstice” day (it actually occurs at the beginning of the winter in the southern hemisphere, so “June solstice is a more accurate term”) the Sun appears to reach its highest point in the sky at the northern hemisphere, at latitudes outside the tropics. Also, the longest day time and shortest night time of the year occur. Within the tropics, the Sun appears directly overhead at solar noon days to 3 months before and after the summer solstice.
