Before Hubble was launched in 1990, the estimates of the Hubble constant varied by a factor of two.───哈勃望远镜1990年发射前，哈勃常数的估值受计算因子该取1还是2的影响而各不相同。
For the measured value of the Hubble constant, this distance is about 14 billion light - years .───由量测到的哈伯常数值来推断, 这个距离大约是140亿 光年 远.
The most widely accepted value for the Hubble constant right now is 72 kilometers per second per megaparsec, obtained by the Hubble Space Telescope.───目前哈勃常数最被广泛认可的值是每秒每百万秒差距72千米，这个值是由哈勃空间望远镜测出的。
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.───但是，没有人因为坚持了错误的哈勃常数而被送进监狱，永远都允许建立在数据之上的讨论。
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.
Measuring the Hubble constant was one of the three major goals for NASA's Hubble Space Telescope before it was launched in 1990.
It indicates that the Hubble constant is large – and therein lies a big problem.
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.
The most widely accepted value for the Hubble constant right now is 72 kilometers per second per megaparsec, obtained by the Hubble Space Telescope.
For the measured value of the Hubble constant, this distance is about 14 billion light - years .
The Virgo Cluster distance has been used to give an important determination of the Hubble Constant and the scale of the Universe.
A Hubble constant of is obtained fromobservati 0 ns of a distant Type II SN 1992 am.
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.
