The temperature of a star affects its color. Red= coolest Orange/Yellow= cool, but hotter than red ▪ Our sun is an orange/yellow star
White= hotter Blue-‐white=hottest!

The Corona is the gasses all around the star. Think of it like the Earth’s atmosphere.

A Red Dwarf is the second stage a star goes through.
A White Dwarf forms when a small star is near the end of its life
A supernova is when a large star explodes before going out!

Some supernovas then collapse into black holes, but only if they are large enough have a strong gravitational pull.

There are millions of galaxies in the universe!
Some can be seen without a telescope.

Constellations often change because: The Earth rotates around the sun, changing the angle and direction from which we see the stars
The stars are actually moving through space, so the distances between them will change.
