When You Wish upon a Star

play music pause music
mute music

Written by Leigh Harline |  Lyrics by Ned Washington

When you wish upon a star, makes no difference who you are
Anything your heart desires will come to you

If your heart is in your dreams, no request is too extreme
When you wish upon a star as dreamers do

(Fate is kind, she brings to those who love
The sweet fulfillment of their secret longing)

Like a bolt out of the blue, fate steps in and sees you thru
When you wish upon a star, your dreams come true

Is there life on other planets? How large is our galaxy? How is a star formed? When your kids ask you questions like these, you need to be prepared! NASA can help you explain to them what scientists do and do not know about big questions like these.
For kids
What’s out in the sky when you look up at night? People have wondered that for millennia! By learning about space, scientists also learn about Earth’s environment and how it contributes to your and your family’s health and welfare.
