Winter Solstice 2023 The big global moment comes at 10:27 p.m. Eastern time on Thursday, December 21, 2023, the sun shines in the Tropic of Capricorn in the southern hemisphere’s constellation of Capricorn. The winter solstice officially marks the beginning of a new season north of the equator, and the summer solstice south of the equator.

Confused? No way. It’s all a simple story about living on a planet whose axis is tilted. And it’s an opportunity to think about how and why the Sun’s strength increases and decreases throughout the year, how the seasons change, and how celestial mechanics sets the tone for life on Earth.

Winter Solstice 2023

Here’s everything you need to know about this week’s summer solstice and why it’s important.

Summer Solstice Explanation: Winter Solstice 2023

Winter Solstice 2023: Astronomically speaking, it is the beginning of winter in the Northern Hemisphere and the beginning of summer in the Southern Hemisphere. The north has the shortest days and longest nights of the year, while the south has the longest days and shortest nights of the year.

This is the only story about how our planet rotates. The Earth’s axis of rotation is tilted 23.5 degrees, so different parts of the Earth receive sunlight for different amounts of time during one revolution a year around the Sun. It was probably caused by a collision billions of years ago.

During this week’s summer solstice, the Northern Hemisphere is tilted away from the Sun, so the Sun is at its lowest point in the sky. Meanwhile, in the southern hemisphere, the sun is above the Tropic of Capricorn, an imaginary line 23.5 degrees south of the equator, giving that hemisphere enough light to stay in the sky for a long time.

Decisive Moment

The summer solstice marks a decisive moment in the apparent movement of the Sun. “On this day, the sun’s orbit appears to stop and change direction. This phenomenon is where the term ‘solstice’ comes from,” he said. Min-jae Kim, a research fellow in the Department of Physics at the University of Warwick, UK, said in an email. The word comes from the Latin solstitium,'' meaningthe sun standing still.” “This apparent cessation occurs when the sun reaches its southernmost point against the background of stars,” Kim said.

Now the days are getting longer in the Northern Hemisphere, and on the March equinox (same day and night) there are 12 hours of daylight and 12 hours of darkness. At the vernal equinox, the Earth’s axis is next to the sun.

On the June solstice, the situation is reversed and the Sun is above the Tropic of Capricorn at 23.5 degrees north of the equator. Summer is guaranteed in the northern hemisphere and winter is guaranteed in the southern hemisphere.

Effects of Summer Solstice

“The tilt of the Earth’s axis is the main cause of these seasonal variations,” Kim said. “Not only does it affect temperature differences between seasons, but it also changes the length of day and night throughout the year.”

The sun rises and sets at different places on the horizon throughout the year. People who watch sunsets and sunrises instinctively know this, but most of us don’t. The summer solstice represents the pole. For example, on the winter solstice in the Northern Hemisphere, the sun rises in the southeast and sets in the southwest.

These are the farthest points from where you can see sunrise and sunset throughout the year. Wait six months for the summer solstice in June, when the sun rises in the northeast and sets in the northwest in the northern hemisphere. Midterm refers to the vernal equinoxes, which occur, as you might have guessed, in both September and March. During the spring equinox, the sun rises due east and sets due east.

How to Observe the Summer Solstice: Winter Solstice 2023

The Winter Solstice 2023 is an important marker in Earth’s orbit around the sun, but not many people celebrate it, especially since the winter solstice is so close to other festivals.

Of course, a good way to commemorate this event is to watch the sunrise or sunset on the summer solstice. This seems to be commemorated by ancient sites such as Stonehenge, but there are other options as well. One is to go outside after dark and do a little stargazing. This year, you’ll get a great view of the extremely bright Jupiter high in the night sky in the southeast. As a bonus, it can be seen just after sunset.
