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。
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.
其中，速度表示星系后退的速度，H0为哈勃常数，也即宇宙膨胀速率的参数，而距离指的是星系与相比较星系之间的距离。
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。
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.
因此，通过对畸变的观测，可以确定富星系团内电子的密度和温度以及哈勃常数h_0。
