1. A Hubble constant of is obtained fromobservati 0 ns of a distant Type II SN 1992 am.

2. It indicates that the Hubble constant is large – and therein lies a big problem.

3. H0 is the Hubble constant, or parameter that indicates the rate at which the universe is expanding; and distance is the galaxy's distance from the one with which it's being compared.

4. Combining the Hubble constant measurement with estimates for the density of the universe, the team determined that the universe is approximately 12 billion years old - similar to the oldest stars.

5. Measuring the Hubble constant was one of the three major goals for NASA's Hubble Space Telescope before it was launched in 1990.

6. The most widely accepted value for the Hubble constant right now is 72 kilometers per second per megaparsec, obtained by the Hubble Space Telescope.

7. For the measured value of the Hubble constant, this distance is about 14 billion light - years .

8. The Virgo Cluster distance has been used to give an important determination of the Hubble Constant and the scale of the Universe.

9. Hence it is proposed that the temperature and the density of electrons in a rich cluster and the Hubble constant H0 may be determined from the observations of the IR-background distortion.

10. The formula for this is pretty tried and tested, unfortunately it relies on one of sciences only variable constant, the Hubble Constant.

10. Wish you can benefit from sentencedict.com and make progress everyday!

11. Before Hubble was launched in 1990, the estimates of the Hubble constant varied by a factor of two.

12. But nobody was ever sent to prison for espousing the wrong value for the Hubble constant. There is always room for more data to argue over.

13. The team's precise measurements are the key to learning about the expansion rate of the universe, called the Hubble constant.
