Summer Solstice 2016: What Is A Strawberry Moon?

This happens once in 70 years.

The summer solstice, the longest day of the year, is upon us and this year the event is extra special.

Today coincides with the Strawberry Moon, which happens once every 70 years.

The term was coined by early Native Americans, the The Algonquian tribe, to describe the full moon that marks the start of the strawberry picking season.

Every year thousands gather at Stonehenge, Wiltshire, to celebrate the longest day of the year.

Technically, the summer solstice happens because the Earth's tilt towards sun is at its maximum.
