Using telescopes tuned into wavelengths of the electromagnetic spectrum other than visible light, astronomers are able to see the universe in greater detail. The Spitzer Space Telescope studies stars and planetary systems in infrared wavelengths. This interactive feature describes how infrared light can help us better understand the the formation of stars and planets, oddities such as brown dwarfs (stars which lack sufficient mass to 'ignite'), and the deaths of stars in which they become white dwarfs or supernovae. A background essay and list of discussion questions are also provided.
