By the redshift of the galaxies. In general, the farther away a galaxy is from us, the faster it moves away from us.
The age of the universe is inversely proportional to the Hubble constant. A smaller Hubble constant would imply a younger universe, while a larger Hubble constant would suggest an older universe. This relationship is based on the assumption that the expansion rate of the universe has been constant over time.
As proven by Edwin Hubble, the universe is expanding.

Hubble's Amazing Universe - 2008 TV was released on: USA: 5 October 2008
Hubble did not conclude that the Universe is expanding. Hubble thought the red shift indicated a unrecognized principle of nature. Hubble's constant actually shows the universe is bounded at R=150kMpc/31 and H= c/R = 62km/s/Mpc. The increase red shift velocity indicates a decreasing universe.

The inverse of Hubble's constant provides an estimate of the age of the universe.
The furthest Hubble as ever gazed into the universe is the Hubble Ultra Deep Field. Search that in google and check it out.
No, because it will be impossible for the Hubble Space Telescope to map out all 100 billion galaxies in the observable universe.
The Hubble Space Telescope was named after Edwin Hubble. He was not an astronaut. Edwin Hubble was an astronomer, not an astronaut, who discovered the expansion of the universe.
The universe is expanding!
