| These three detectors allow Herschel to see far-infrared and sub-millimetre (radio) wavelengths of light, allowing it to peer through clouds of dust and gas and to see stars as they are born. | These three detectors allow Herschel to see far-infrared and sub-millimetre (radio) wavelengths of light, allowing it to peer through clouds of dust and gas and to see stars as they are born. |
| This infrared capability also enables Herschel to look deep into space, to look at galaxies that thrived when the Universe was roughly a half to a fifth of its present age. This is a period in cosmic history when it is thought star formation was at its most prolific. | This infrared capability also enables Herschel to look deep into space, to look at galaxies that thrived when the Universe was roughly a half to a fifth of its present age.

| Astronomers will continue to study the images, which have already shown that the mechanisms of the cosmos may be more diverse and complex than current theory suggests. | Astronomers will continue to study the images, which have already shown that the mechanisms of the cosmos may be more diverse and complex than current theory suggests. |
