Every year, the Northern Hemisphere experiences the arrival of winter on the winter solstice, which marks the shortest day and longest night due to the Earth's tilt on its axis. As the North Pole is furthest from the sun, it receives the least amount of sunlight, resulting in a gradual lengthening of days towards the arrival of spring. This year, the winter solstice falls on December 21 and will be celebrated by people worldwide in various ways to mark the significant celestial event.
Winter Solstice: The Shortest Day of the Year
The winter solstice is an astronomical event that occurs annually when the Sun reaches its lowest point in the sky as seen from Earth's Northern Hemisphere. This results in the shortest day and longest night of the year.
Background

During the winter solstice, the North Pole is tilted away from the Sun, receiving the least amount of sunlight. As a result, the Northern Hemisphere experiences its shortest day and longest night.
The winter solstice typically occurs around December 21 or 22 in the Northern Hemisphere. This year, the winter solstice will occur on December 21, 2023.

Russian scientists have developed a vaccine that may be able to treat cancer, offering hope to patients who previously had no guaranteed cure. The vaccine is currently in testing and is expected to be available in early 2025. While there is still more testing to be done, pre-clinical trials have shown promising results in slowing the growth and spread of cancer. It will be available for free in Russia, but there is no information yet on which types of cancer it will treat or what the name of the vaccine will be. Similar treatments are also being developed in other countries, such as the UK.
