Douglas Adams told us the answer to life, the universe and everything is 42. If only cosmology were so straightforward. Astronomers have been arguing for years about a number every bit as fundamental, ...
Cousins says he is “hopeful” that the findings of gravitational-wave cosmology will be able shed more light on the Hubble ...
Astronomers have made new measurements of the Hubble Constant, a measure of how quickly the Universe is expanding, by combining data from the Hubble Space Telescope and the James Webb Space Telescope.

For decades, astronomers have been trying to nail down the value of the Hubble constant—a measure of how fast the universe is expanding. But some cosmologists say there’s evidence that the universe is ...
Whatever dark energy is, explanations for it have less wiggle room following a Hubble Space Telescope observation that has refined the measurement of the universe’s ...
A critically important number that specifies the expansion rate of the Universe, the so-called Hubble constant, has been independently determined using NASA’s Chandra X-ray Observatory. This new value ...
Primordial magnetic fields may help explain why measurements of the universe’s expansion do not agree. Scientists have long known that the universe is expanding, yet there is still no agreement on how ...
The idea that the universe is expanding dates from almost a century ago. It was first put forward by Belgian cosmologist Georges Lemaître (1894–1966) in 1927 and confirmed observationally by American ...
Since its launch in April 1990, the Hubble Space Telescope has been an invaluable tool for astronomers in unraveling the ...
