GORAJUARA – Astronomers estimate that the universe can accommodate up to a septillion stars.
The Milky Way as our galaxy itself contains more than 100 billion stars, including our most studied star, namely the Sun.
Stars are giant balls of hot gas formed from mostly hydrogen with some helium and a number of other small elements.

Each star has its own life cycle, which ranges from several million to trillions of years and its properties change as it ages.
However, how do stars actually form in the first place?
Check out the explanation below.

The beginning of the stars
Reporting from the science.nasa.gov site by GORAJUARA, stars form in large clouds of gas and dust called molecular clouds.
These molecular clouds range from 1,000 to 10 million times the mass of the Sun and can reach hundreds of light years.
Molecular clouds are cold which causes gas to clump and create pockets at high speed.

Some of these clumps can collide with each other or collect more material, strengthening their gravitational force as their mass increases.
