Stars Explanation

Why are stars only visible after sunset?

Where do the stars go during the day? Has that question ever crossed your mind? Stars are luminous points in the sky which are large balls of gas made of Hydrogen and Helium, the two lightest elements in the universe.

During the day the stars are still there, we just can’t see them because when our part of the Earth faces the sun, giving us daytime; the sun’s rays scatter across the atmosphere making the sky blue and the stars invisible to the naked human eye. For example: When you light a candle, it’s easier to see the glow in the dark than in the light.

According to global information, when the temperature of a cloud’s center reaches many millions of degrees centigrade (Celsius), Hydrogen Nuclei within the clouds start to collide with one another, they form Helium Nuclei. This is called Nuclear Fusion (Nuclear reaction), and huge amounts of energy are released; mostly heat.

Next, the center of the of the cloud starts to ‘burn’ and a star is born. After a new star is formed, energy produced by the Nuclear Fusion causes it to swell like a balloon. As long as this energy is balanced by gravity, the star will remain stable because just as the fusion causes the star to expand, gravitational energy tries to compress it. The stability can last for millions of years.

Did you know that the surface temperature of a star can range from 3,000 to over 50,000 Celsius? The surface temperature of a star will determine its colour; the cooler stars are red and the hotter stars are blue. The temperature also affects the brightness of a star, the hotter the star is, the brighter it will be.

Many minds never realize that the stars are still there, but they truly are. They’re not visible due to the rays received from the  sun making the sky blue. This causes the sky to be too bright for the stars to outshine the sky. Take into recognition that at night, we can see the stars because the sky isn’t bright, just a dull black canvas awaiting to be known of its existence behind the superior blue cloak.

This is my explanation about why stars aren't visible during the day.
