Will the stars in the sky shine by themselves?

Some glow, some don't. Because stars include planets, stars, comets, white dwarfs and so on. The planet itself does not shine, what we see is the sunlight it reflects. A star is a big celestial body like the sun, which will react on its own and radiate energy into space in the form of light. When the light it emits is visible to our naked eyes, we say it will shine.

Extended data:

There are two main factors that determine whether people observe the stars bright or dark: one is the luminous ability of the stars, and the other is the distance between the stars and people. Astronomers usually divide the luminous power of stars into 25 magnitudes, and the difference between the strongest luminous power and the worst luminous power is about 65.438+000 billion times. Stars close to people have strong luminous ability, so people will light up when they see them.
