Hubble constant
The Universe is expanding nine per cent faster than expected, Hubble data suggests
New findings indicate that the Universe is growing at a faster rate today than in the Universe's early days
Astronomers probe quasars from just after the Big Bang to calculate the expansion rate of the Universe
They found that the Universe is actually expanding faster than predicted by the standard model of cosmology
New estimate of Hubble constant derived using a doubly imaged quasar
The Hubble constant is a number that relates distances in the universe to the redshifts of galaxies
'Very accurate' understanding of Universe's expansion will take scientists 5-10 years to calculate
Are pinning down the exact rate of expansion of the Hubble constant
