Quick Answer: What is responsible for making stars shine?

What is responsible for making stars shine quizlet?

Stars shine because hydrogen fusion takes place inside their core which creates energy.

What is responsible for making stars shine Brainly?

The light energy emitted at the core of stars is carried by photons. Thus, we can say that photons is responsible for making stars shine.

What is responsible for making stars shine protons the sun the moon photons?

What is responsible for making stars shine protons the sun the moon photons? The simple answer is that deep inside the core of the Sun, enough protons can collide into each other with enough speed that they stick together to form a helium nucleus and generate a tremendous amount of energy at the same time.

What causes a star to shine brighter?

A star’s brightness also depends on its proximity to us. The more distant an object is, the dimmer it appears. Therefore, if two stars have the same level of brightness, but one is farther away, the closer star will appear brighter than the more distant star – even though they are equally bright!

What force is responsible for crushing or collapsing stars?

Gravity constantly works to try and cause the star to collapse. The star’s core, however is very hot which creates pressure within the gas. This pressure counteracts the force of gravity, putting the star into what is called hydrostatic equilibrium.

What is the name of Red Star?

Antares: Red Star at the End of Its Life.

What color is the hottest star?

White stars are hotter than red and yellow. Blue stars are the hottest stars of all. Stars are not really star-shaped.

What happens when a star begins to run out of fuel?

When a main sequence star begins to run out of hydrogen fuel, the star becomes a red giant or a red super giant. THE DEATH OF A LOW OR MEDIUM MASS STAR After a low or medium mass or star has become a red giant the outer parts grow bigger and drift into space, forming a cloud of gas called a planetary nebula.

What happens first when a star begins to run out of fuel?

Explanation: When a star starts running out of fuel the pressure in the core becomes very high which pushes the outer layers of the star. A sun like star becomes a red giant and after throwing away the mass, the core contracts to becomes a white dwarf.

What causes the sun to shine?

The Sun shines by turning hydrogen into helium in its core. This process is called nuclear fusion. Fusion happens when lighter elements are forced together to become heavier elements. When this happens, a tremendous amount of energy is created.

At what temperature does nuclear fusion begin?

The collisions which occur between the hydrogen atoms starts to heat the gas in the cloud. Once the temperature reaches 15,000,000 degrees Celsius, nuclear fusion takes place in the center, or core, of the cloud.

Why do stars shine only at night?

Stars are present in the sky at both day and night. During the day, the light of the Sun makes our sky so bright that we cannot see the much dimmer stars. At night, in the absence of the Sun, the sky becomes dark and the light of the stars can be seen. That is why, we are able to see the stars clearly only at night.

Do stars shine on their own?

Stars make their own light, just like our sun (the sun is a star — the closest star to Earth). They reflect the light of the sun in the same way our moon reflects sunlight. SpaceKids on SPACE.com provides simple, straightforward answers to really big cosmic questions.

What is the brightest star?

Sirius, also known as the Dog Star or Sirius A, is the brightest star in Earth’s night sky. The name means “glowing” in Greek — a fitting description, as only a few planets, the full moon and the International Space Station outshine this star.

Are hotter stars brighter?

Stars on the Main Sequence that are hotter than the Sun are also larger than the Sun. So hot blue stars are more luminous (and therefore appear higher in this diagram) for two reasons: they are hotter, and hot objects are more luminous than cool objects, but they are also larger.
