Light is one of the most amazing and important aspects of the universe. There are two types of light sources, namely natural and artificial light sources.
One real example of a natural light source that can be enjoyed is the sun.
Every day, its rays provide the light and heat that make life on Earth possible.
Not only the sun, it turns out there are various other natural light sources that have various benefits for everyday human life.
Are you curious about examples of natural light sources? If yes, see the explanation below.

Explanation of Natural Light Sources

Natural light sources are anything or natural phenomena that produce light without human intervention.
This natural light comes from natural sources that do not require combustion or artificial lighting.
Natural light sources have an important role in ecosystems, human life, and also have great artistic and scientific value.
This source plays an important role in maintaining human circadian rhythms, supporting ecosystems, and providing inspiration for art and scientific research.
By understanding and appreciating natural light sources, Moms can benefit from each source.

Natural Light Source
As mentioned previously, one of the sources of light present on the face is natural.
Quoting from Byjhere are some natural light sources that Moms can teach your little one.
1. Sun

The sun is the most important and dominant natural light source in our solar system.
It is the central star of our solar system, and plays a huge role in maintaining life on Earth.
The sun is a huge, hot fireball giant at the center of the solar system.
In its core, nuclear reactions occur that produce enormous energy.
This energy is emitted in various forms, including light and heat.
The light emitted by the sun is the main source of natural light in our solar system.
Sunlight is essential for life on Earth.
Plants use sunlight in the process of photosynthesis to produce their own food, and herbivorous animals consume these plants.
In other words, the sun is the primary energy source for all living things on Earth. Sunlight also influences our planet’s climate, weather and seasons.
Apart from light, the sun also produces enormous heat.
This heat influences Earth’s climate and allows life to survive.
There are various technologies, such as solar panels, that convert the sun’s heat into energy used in various applications, such as electricity generation and water heating.
2. Bintang

Stars are amazing sources of natural light in the universe.
Although the sun is our closest star and the main source of light in our solar system, stars also play an important role as natural light sources.
Stars are celestial bodies that produce light and heat through nuclear reactions in their cores.
This is what causes the stars to sparkle in the night sky. This light reaches the Earth and gives us the beautiful illumination of the night sky.
At night the stars provide natural lighting when the sun has set below the horizon.
Then, stars also give us a view of the sky full of sparkling light, and star patterns that change over time.
Until now, the stars are also used by humans as directions and navigation on sea or land.

3. Moon

The moon is an example of a natural light source in the sky and has an important role in night lighting.
However, it is important to note that the Moon itself does not produce light.
Instead, it reflects light from the sun.
Moonlight is natural light that is visible in the night sky when the moon rises and is in the sky.
This makes the night brighter and allows us to see outdoors without the help of artificial light.
Moonlight also provides a beautiful and calming appearance in the night sky.
One of the interesting characteristics about moonlight is that the moon experiences different phases, such as full moon, half moon and crescent moon.
These phases are caused by changes in the relative positions of the Moon, Earth, and sun.
Moonlight not only provides useful nighttime lighting, but also has an influence on the Earth’s geology.
For example, ocean tides are caused by the moon’s gravitational pull.
Then the moon has also been a source of inspiration in art, mythology and human culture throughout history.
4. Living Organisms That Are Capable of Emitting Light

Living organisms that have the ability to produce natural light are known as bioluminescent organisms.
Bioluminescence is the ability of living organisms to produce light through chemical reactions in their bodies.
This reaction involves a chemical called luciferin, the enzyme luciferase, oxygen, and calcium ions.
When luciferin and oxygen react in the presence of luciferase, it produces light that is cold (without heat).
The result is natural light emanating from the organism’s body.
There are a wide variety of bioluminescent organisms in nature, including:
DragonflyJellyfishGlow wormBioluminescent plankton
5. Lightning

Lightning is a natural phenomenon that produces very dramatic and spectacular natural light.
Although lightning itself is not a natural light source like the sun or stars, the light produced by lightning is very powerful.
Lightning is formed as a result of the movement of electric charges in clouds.
When the particles in a cloud move and interact, different electrical charges separate, creating a positive charge at the top and a negative charge at the bottom.
So this creates electrical tension within the cloud.
Lightning light can have a variety of colors, including white, blue, red, or purple.
This color depends on the chemical composition of the atmosphere at the time of release. The shape of lightning can also vary, from straight flashes to complex branching flashes.
Then the light produced by lightning is very bright, it can even exceed the brightness of the sun when it occurs at a very close distance.
This brightness is caused by the very high temperatures in the lightning light channel, which can reach around 30,000 degrees Celsius.
