Summer Solstice: The Longest Day

The summer solstice, occurring between June 20 and 22 in the Northern Hemisphere, marks the zenith of the sun's annual journey across the sky. This astronomical event signifies the longest day and shortest night of the year, as the Earth's axis is tilted most directly towards the sun.

The term 'solstice' derives from the Latin words 'sol' (sun) and 'stitium' (standing still), aptly describing the sun's apparent pause before it begins its southward retreat. This celestial phenomenon has been revered throughout history, with ancient civilizations constructing monumental structures like Stonehenge to align with the solstice sun.

Astronomically, the solstice represents the moment when the sun reaches its northernmost point from the celestial equator. This occurs due to the Earth's 23.5-degree axial tilt and its elliptical orbit around the sun. Following the summer solstice, the days progressively shorten until the winter solstice in December, completing the annual cycle of seasons.

It's important to note the distinction between astronomical and meteorological seasons. While astronomical seasons are determined by the Earth's position relative to the sun, meteorological seasons are based on annual temperature cycles, with summer beginning on June 1 in the Northern Hemisphere.
