Why are stars are not visible during daytime? Fine & Yvette

Have you ever wondered why stars aren’t visible during daytime? Majority of people believe that stars have disappeared as the sunset rises, but stars are still there, just hiding. Stars are hidden behind the bright blue rays that are received from the Sun.


Stars are luminous points in the night sky. They are produced when a nebulae (spinning tornado of gases, dust and cloud) creates a ball of helium and hydrogen. Soon, this sphere flames up and creates a star. When the helium and hydrogen gases interact with each other, they form an explosion or scientifically known as a ‘Nuclear fusion’. The more nuclear reactions that occur on this star, the brighter the star becomes.

As the Earth is spinning on its own axis, it absorbs darkness from the moon and light from the Sun. This is because one side of the Earth is facing the bright light from the Sun, while the other is facing the dark moon. It’s like when a person is facing the light, and the back of their body is dark. This creates the illusion of day and night. Due to the Suns bright blue light, we are not able to see the stars that are actually still there. Luckily as night falls, the stars shine brightly and are visible to the human naked eye.


Isn’t it amazing how we aren’t able to see stars at daytime, when they’re actually still there? Inside the storage of many minds, you will not discover information about why we aren’t able to see stars in sunlight. The world of astronomy may be big, but its a triumph to know we both have learnt just a small amount of knowledge about it.
