The Hubble Time Machine

More

In this short documentary, astronomers explain how the orbiting telescope allows us to see deep into the past and predict the future. Since it launched 22 years ago, Hubble has sent back stunning images of the far reaches of the universe, capturing light that has traveled for billions of years to reach Earth. Measuring the colors of stars allows scientists to determine how old galaxies are, and whether they're traveling towards or away from us. This data, in turn, suggests that the age of the universe is 13-14 billion years old -- one of Hubble's most important scientific contributions. This video models the Doppler effect (the physics at work in these discoveries) with a portable stereo strapped to a remote-control rover, blasting banjo music while driving around a mini model Hubble. Check it out, and then browse more amazing Hubble images over at Alan Taylor's In Focus advent calender.
