People also ask

Did you know about stars?

The average star is between 1 and 10 billion years old, although some stars are older than this. Large stars live shorter lives compared to smaller stars, because large stars burn through their fuel much faster. Giant stars explode into a bright supernova when they die.

What are stars made of facts?

Nearly all stars are made up mostly of a gas called hydrogen. A star's core is very hot. Great pressure squeezes the core, causing some of the hydrogen to change into a gas called helium. This process produces huge amounts of energy and makes the star shine.

How old is a star?

According to our best available estimates, stars having about 90 percent of the sun's mass are just now starting to die in the globulars. These stars are most probably around 15 billion years old, but they could conceivably be as young as 12 billion years or as old as 18 billion years.

How old can stars get?

Some will exhaust their available hydrogen within a few million years. On the other hand, the least massive stars that we know are so parsimonious in their fuel consumption that they can live to ages older than that of the universe itself--about 15 billion years.

How is a star born?

A star is born when atoms of light elements are squeezed under enough pressure for their nuclei to undergo fusion. All stars are the result of a balance of forces: the force of gravity compresses atoms in interstellar gas until the fusion reactions begin.
