>The team used Hubble to observe the light from six faraway quasars. The telescope observed how the light from each quasar was multiplied into four images by the gravity of a massive foreground galaxy. The galaxies studied are 3 billion to 6.5 billion light-years away. The quasars' average distance is 5.5 billion light-years from Earth.

>The results show that for every additional 3.3 million light-years away a galaxy is from Earth, it appears to be moving 73 kilometers per second faster
