The Surprising Reason Behind Earth's Summer Solstice
The summer solstice, marking the beginning of astronomical summer in the Northern Hemisphere, occurs on June 21 at 4:25 a.m. ET. This day is characterized by the most hours of daylight of the year, with the Sun at its highest point in the sky. Although it may have felt like summer for several weeks in parts of the US, the peak temperatures are yet to come, typically lagging behind the solstice due to the time required for ground and water to heat up.
The Earth's seasons are caused by the tilt of its axis, which remains constant as the planet orbits the Sun. The summer solstice occurs when the Northern Hemisphere is tilted towards the Sun, receiving the most direct and intense sunlight of the year. This tilt is believed to be the result of collisions with protoplanets and massive objects during the solar system's formation.
Solstices, occurring in June and December, mark the beginning of astronomical summer and winter, while equinoxes in March and September signal the start of spring and autumn. The summer solstice is distinct from the winter solstice, which occurs when the Sun is at its lowest point in the sky. According to NASA, NOAA, and other scientific sources, the Earth's tilt is responsible for the changing seasons, with the summer solstice marking the beginning of the warmest period of the year.
