| At the meeting, Freedman reported a Hubble constant of about 73 kilometers per second per megaparsec, which corresponds to a universe between 9 and 12 billion years old. |
| The Milky Way Galaxy is one of the Local Group of galaxies, which contains more than three dozen members and extends over a volume about one megaparsec in diameter. |
| From this measurement, they calculated a Hubble constant of 80 kilometers per second per megaparsec. |
| Using four different ways to measure distances in the cosmos, the astronomers find a Hubble constant of 70 kilometers per second per megaparsec. |
| The average value of Hubble's constant derived from these many different measurements was about 50 km per second per megaparsec. |
