How do light-years help astronomers to determine the ages of distant objects in space?

To calculate an object's distance from Earth in light-years, astronomers must first know the object's age in years.

Light in space travels approximately 9.5 trillion km per year. Therefore, the images that astronomers see of distant objects actually show what those objects looked like long ago.

Light in space travels approximately 9.5 trillion km per year. Therefore, an object's distance from Earth in light-years is equivalent to the object's age in years.
