Peak Sunshine has arrived in the Northern Hemisphere – Summer Solstice.
Friday is the longest day north of the equator, and bliss marks the beginning of an astronomical summer. It is the opposite of the Southern Hemisphere, where it is the shortest day of the year and winter begins.
The word “bliss” comes from the Latin word “sol” for the sun and the “sol” in “stitium,” meaning “stop” or “stop.” Bliss is the end of the Sun’s annual march, drawing the longest and best arc in the sky. Bad news for sun lovers: it begins to retreat, and every day is a little shorter each day until late December.
People have been celebrating the solstice for many years, including celebrations and monuments including Stonehenge, designed to align with the solar path of sontice. But what is happening in heaven? This is what you need to know about Earth’s orbit.
Bliss is when day and night are at their most extremes
When the Earth moves around the Sun, it does so at an angle relative to the Sun. For most of the year, the Earth’s axis tilts towards or away from the Sun. It means that the warmth and light of the sun falls unequally into the northern and southern half of the planet.
Bliss marks an era of the year in which this slope is at its most extreme, with day and night being the most unequal.
During the summer solstice in the Northern Hemisphere, the upper half of the Earth tilts towards the sun, creating the longest and shortest nights of the year. This bliss falls between June 20th and 22nd.
Meanwhile, on the winter solstice, the Northern Hemisphere is fleeing the sun. The winter solstice will fall from December 20th to 23rd.
The equinox is when there is an equal amount of day and night
During the equinox, the Earth’s axis and its orbit are lined up, so both hemispheres get equal amounts of sunlight.
The word equinox comes from two Latin words, meaning equal and night. This is because on equinox, day and night are roughly the same time.
Spring in the Northern Hemisphere, or Spring, can land between March 19th and 21st, depending on the year. That fall, or in autumn – equinox can land between September 21st and 24th.
At the equator, the sun goes directly overhead at noon. The equinox is the only time both the Arctic and Antarctic are illuminated simultaneously by sunlight.
The seasons are changing, so please mark your calendar! This is something you need to know about equinox and solutes.
What is the difference between weather and astronomy seasons?
These are two different ways to carve out the year.
Astronomical seasons depend on how the Earth moves around the Sun, but weather seasons are defined by weather. They break down the year into three months of seasons based on the annual temperature cycle. By that calendar, spring begins in the summer of March 1st and June 1st, followed by winter on September 1st and December 1st.
