The staggering abundance of stars in the universe is a truly breathtaking phenomenon. Just within our own galaxy, the Milky Way, there exist over 100 billion stars. But how many are there in the entire universe? Scientific research indicates that the number of stars surpasses even the number of grains of sand on Earth.

Stars that twinkle in the night sky do not twinkle on their own; rather, it is an illusion created by the Earth’s atmosphere. Different layers of the atmosphere, with their specific characteristics, affect our perception of starlight. The atmosphere refracts and scatters light, creating the flickering effect. To mitigate the impact of the atmosphere, astronomers employ various systems in their telescopes.

Another illusion created by the atmosphere is our perception of the color of the Sun. Although we see it as yellow, the Sun actually has a white color. Our atmosphere scatters shorter wavelengths, such as blue light, while longer wavelengths, including yellow and orange, directly reach our eyes, giving the Sun its distinctive brightness.

It is not possible to accurately count all the stars in the universe, but according to NASA’s estimates, their number exceeds the number of grains of sand on Earth. It is estimated that there are around 1 quadrillion stars, while the number of grains of sand is estimated to be around 7.5 trillion.

Unfortunately, the number of visible stars in the night sky is decreasing year by year. Increased “light pollution” due to population growth, urban expansion, and widespread use of LED lighting leads to reduced visibility of stars. We need to be aware of this trend and make efforts to preserve the natural darkness of the night sky.
