You can see stars fading away at dawn and appearing at dusk. During the day we do not see the stars. Explain why.
Stars fade away at dawn and appear at dusk because of the extreme brightness of the Sun.
During daytime, the Sun's brightness is so intense that it outshines all other stars, making them invisible to our eyes. The scattered sunlight in the atmosphere creates a bright blue sky that overwhelms the faint light from distant stars.
At dawn and dusk, when the Sun is below the horizon, its brightness decreases, allowing the fainter stars to become visible again.
The stars are still present in the sky during the day, but the Sun's overwhelming brightness prevents us from seeing them.
Explanation
The chapter explains on Page 10 that during daytime, due to the extreme brightness of the Sun, it is not possible to view the other stars. The Sun is much closer to us than other stars, so it appears much bigger and brighter. As stars are much farther away, they appear like points and are not visible during daytime because of the Sun's brightness.
Solution Steps
Stars fade at dawn and appear at dusk due to the extreme brightness of the Sun.
During daytime, the Sun's intense brightness outshines all other stars, making them invisible.
Scattered sunlight in the atmosphere creates a bright blue sky that overwhelms the faint light from distant stars.
At dawn and dusk, the Sun is below the horizon, reducing brightness and allowing stars to become visible.
Stars remain present in the sky during the day but are hidden by the Sun's overwhelming brightness.
