Just the other night, I grabbed my binoculars and looked up to the starry sky. At first the stars looked white, but when I looked closer I noticed some appeared more blue and red.
I was curious to find out exactly what color they were, so I visited my friend George Newman. He’s a physics and astronomy instructor at Washington State University.
He said that a star mostly emits the kinds of light that our eyes see as red or blue.
“The thing that determines which color they give off most is their temperature,” he said.
