Simple and fun learning activities to share with children.
Clues from Ancient Light—With the GALEX space telescope, astronomers know the age of a source's light by its degree of red shift. In this learning-by-analogy activity, kids arrange pictures of familiar objects by judging which is older.
Paint by Pixels—Make a picture using a technique similar to that used by many NASA spacecraft to record and send pictures back to Earth.
