Learn how Hubble is measuring the expansion rate of the Universe in this new explainer from NASA's Goddard Space Flight Center. Credit: NASA's Goddard Space Flight Center Producer & Director: James ...

The Universe really seems to be expanding fast. Too fast, even. A new measurement confirms what previous — and highly debated ...

Or, more precisely, astronomers have used multiple methods of estimating the Hubble constant, and the different methods are converging quite tightly on two different values! This clearly can’t ...

He announced his finding in 1929. The ratio of distance to redshift was 170 kilometers/second per light year of distance, now called Hubble's constant. The numbers were not exactly right ...

Edwin Powell Hubble is renowned for determining that there are other galaxies in the Universe beyond the Milky Way, and for observing that the universe is expanding at a constant rate. Hubble was ...

The rate of cosmic expansion is now known as the Hubble Constant. Ironically, Hubble himself never fully accepted the runaway universe as an interpretation of the redshift data. He suspected that ...
