Northern lights occur roughly every eleven years. Record-keeping of the sun's activity began in 1749. Since then, there have been 22 full cycles.
Particles ejected from the sun travel 93 million miles toward Earth before they are drawn toward the magnetic north and south poles. As the particles move through the Earth's magnetic shield, they mix with the oxygen, nitrogen, and other elements that result in the display of lights.

The availability of experiencing the four seasons of spring, summer, autumn, and winter depends on your location.
Those who live in the countries near the equator experience constant temperatures throughout the year where winters and summers are indiscernible due to their position on the outer curve of the earth where it receives constant light from the sun. While areas in the north and south are able to experience the changing of seasons more significantly.
The reason we experience seasons is because of the tilting of the earth towards the sun. How the planet rotates around its axis affects the way we experience the seasons. Such as the summer and winter solstice being our longest and shortest days of the year.
Moreover, other factors also affect the way we experience seasons significantly, therefore the seasons have a wide variety of what we may experience during the year and current location.

Dark Matter is a bizarre, unknown ingredient of the universe, which scientists cannot observe directly, but takes up 80 percent of the mass of the universe.
It is not seen by the naked eye ...
The way massive objects of the universe bend and distort gravity and light indicates to scientists about the existence of dark matter. The way large objects move about in the universe (velocity) also is a factor pushing towards the probability of much more mass than is visible.
Dark matter provides the gravity and weight in galaxies, which would fall apart if all they had was what is visible to scientists via their various instruments.
