“The Hubble Space Telescope: Time Machine to the Galaxies” explains that, because the Hubble views galaxies that are very distant, the light it captures in its images is billions of years old. Therefore, the Hubble can help us understand the events that took place billions of years ago and how galaxies form. An accompanying educator’s guide includes discussion questions and answers as well as definitions for key terms.
