Star Fall

Do you have freckles on your face? Are they all round and brown? Look closely. Stars are like freckles. They appear to be white and star-shaped. But let's look closer.

You can tell a lot about a star by its color. You can tell the temperature of the star. Red stars are the coolest. Yellow stars are hotter than red stars. White stars are hotter than red and yellow. Blue stars are the hottest stars of all.

Stars are not really star-shaped. They are round like our sun. Most stars are so much farther from us that they are not as bright as the sun. Many stars are bigger and hotter than the sun.

The light from a star moves through Earth's air. Air is always moving and changing. The air makes the starlight bend and scatter. This makes the star appear to twinkle.

There are more stars in the sky than freckles on your face. Just like freckles, each star is different. Go outside and look at the stars at night. They are freckles in the sky!
