What makes a star a star?

Every star has a story. Through every phase of their existence, stars release the energy that powers the universe. Join Mike Likes Science on a musical adventure about one of our sky’s greatest wonders.

Let’s Think…

What new words did you learn?

What’s the difference between stars and planets?

Why do scientists study the stars?

Are all stars the same or are there different types of stars?

What’s the Science?

Stars are giant spheres of superhot gas made up mostly of hydrogen and helium. Stars get so hot by burning hydrogen into helium in a process called nuclear fusion. This is what makes them so hot and bright. As the hydrogen gas in a star is squeezed due to gravity, it produces huge amounts of energy, which make it glow.

The size, temperature, brightness, and color of stars vary. The color of a star is determined by its temperature. Red stars are cooler in temperature, blue stars are hottest, and other stars like ours (which is yellow) are an in-between temperature.

Our star, the sun, is average in terms of size and brightness. However, our star is extraordinarily important! Earth is the perfect distance from the sun. The sun provides heat and light to our planet, supporting life on Earth.
