Spring has sprung - at least it has for those in the northern hemisphere.
At 04:30 GMT on Sunday, the sun crossed the celestial equator heading towards its most northerly point, the Tropic of Cancer, at the summer solstice.
The spring and autumn equinoxes mark the point when hours of night and day are nearly equal right across the globe.
Sun worship was one of the main forms of religious practice among our ancestors, and there are stlll plenty of people who at least acknowledge the "other world" significance of the sun and moon.
Ancient sites such as Glastonbury and Stonehenge in the UK are thronged with sun worshippers, as well as those looking to feel the vibe of these ancient sites at significant times of the sun's cycle.
