What will happen to the sun after it dies?

When it starts to die, the Sun will expand into a red giant star, becoming so large that it will engulf Mercury and Venus, and possibly Earth as well. Scientists predict the Sun is a little less than halfway through its lifetime and will last another 5 billion years or so before it becomes a white dwarf.

How do stars and planets form and evolve?

The Sun is the closest star to Earth, and the single most important influence on the worlds of the Solar System in terms of the light and particles it emits. Studying the Sun, in other words, helps us understand the habitability of Earth, but also other stars elsewhere in the universe. One important solar observatory is the Japanese Aerospace

Are All Stars Suns? A Mystery Uncovered

Stars were first known to be suns around 450 B.C., when the ancient philosopher Anaxagoras proposed the idea that stars and the Sun are the same thing, just at diferent distances. This started a debate among philosophers and scientists of the time, with Aristarchus making a similar suggestion about 220 B.C.

Ask a Solar Physicist

Anaxagoras, who lived in Athens, Greece, around 450 BC (about 2450 years ago), thought that the Sun and stars were fiery stones, that the stars were too far away for their heat to be felt, and that the Sun was perhaps more than a few hundred miles in size. With that Anaxagoras was, as far as we know, the first one to suggest that the Sun is a star.

Stars and Nebulas

Smaller stars like our sun end their lives by ejecting their outer layers of gas into space over the course of about 10,000 years, leaving behind the star''s hot core — a white dwarf. Radiation from the white dwarf causes the gas to glow, creating a unique and beautiful formation called a planetary nebula. The name comes from the early days

Our own sun is a star. Fortunately, we are far enough away from it that the gravity of the gas can''t pull us in. It would be rather unpleasant inside of a star. The gravity is strong enough that it squeezes the gas together so tight that nuclear fusion occurs. That means that the nuclei (centers) of the atoms get stuck together and ''fuse''.
