where do stars get their light

Question: "How can the light of stars billions of light years away from the earth have reached us if the earth is only thousands of years old?"

Stars are huge celestial bodies made mostly of hydrogen and helium that produce light and heat from the churning nuclear forges inside their cores. It reflects light from the sun and stars, which gives it the appearance of producing it’s own light. Stars and Their Fates. That’s a good question! Until about two hundred years ago, everyone that studied the stars thought that all stars were … Continue reading "Why are stars different colors?" The moon does not have it’s own light. How? The light that leaves the star is not coming directly from nuclear fusion. A supergiant star can be 600 million miles (1 billion km) across, but a neutron star is only the size of a city. There are about 6,000 or so stars that are visible with the naked eye, and the vast majority of them are within about 1,000 light-years of the Sun.

For example, hot blue-white stars can reach 54,000°F (30,000°C) at their surface, ten times hotter than the coolest stars. In general, the larger a star, the shorter its life, although all but the most massive stars live for billions of years. To the naked eye, most of the stars appear white. All objects in our solar system get their light from the sun. As the light from the stars comes through the earth’s atmosphere, they appear to be twinkling.

Stars can be very different from each other—in color, brightness, temperature, size, and mass.

We are actually seeing the moment that each sun released the energy that had waited and fought to get outside of the sun and was carried through the universe to us.

Aside from our sun, the dots of light … When a star has fused all the hydrogen in its core, nuclear reactions cease. Depending upon the distance, some of the light that is shining could have come from stars that gave off that light millions of years ago. A star is an astronomical object consisting of a luminous spheroid of plasma held together by its own gravity.The nearest star to Earth is the Sun.Many other stars are visible to the naked eye from Earth during the night, appearing as a multitude of fixed luminous points in the sky due to their immense distance from Earth. Deprived of the energy production needed to support it, the core begins to collapse into itself and becomes much hotter.
