In news- Summer Solstice, the Longest Day of the Year, falls on June 21.
- Solstice means “sun stands still” in Latin.
- It is an astronomical event that occurs twice in a year, once in summer (June) and once in winter (December).
- Summer solstice refers to the longest day and the shortest night of the year in the Northern Hemisphere.
- The longest day does not necessarily mean that it brings the earliest sunrise or latest sunset and depends on the latitudinal location of the country.
- Technically, the solstice occurs when the sun is directly over the imaginary Tropic of Cancer or 23.5°N latitude.
- The other names of Summer Solstice are Estival solstice or midsummer. .
- The Northern Hemisphere gets more direct sunlight and heat from the Sun owing to the earth’s axis’ maximum inclination towards the Sun between March and September.
- During the solstice, the Earth’s axis is tilted in a way that the North Pole is tipped towards the sun and the South Pole is away from it.
- According to NASA, the amount of incoming energy the Earth received from the sun on this day is 30 percent higher at the North Pole than at the Equator.
- In contrast, the Southern Hemisphere receives most sunlight on December 21, 22 or 23 when the northern hemisphere has its longest nights– or the winter solstice.
