HOW STARS ARE FORMED AND HOW DO THEY DIE

HOW WERE STARS FORMED ?

STARS WERE BORN WITHIN THE CLOUDS OF DUST AND SCATTERED THROUGHOUT MOST GALAXIES A familiar example of such as a dust cloud is the Orion Nebula

The Orion is a diffuse nebula situated south of the orions belt

MAIN SEQUENCE STARS A star the size of our Sun requires about 50 million years to mature from the beginning of the collapse to adulthood. Our Sun will stay in this mature phase for about 10 million years

HOW DO STARS DIE ? Most stars take millions of years to die. When a star like the Sun has burned all of its hydrogen fuel, it expands to become a red giant while the rest of the stars become white dwarfs then cools down and becomes invisible.

Tip: The larger a star, the shorter its life, although all but the most massive stars live for billions of years
