Cousins says he is “hopeful” that the findings of gravitational-wave cosmology will be able shed more light on the Hubble ...

A team of cosmologists in China has introduced a mathematical framework that investigates two of the deepest mysteries in ...

Astronomers working with the Dark Energy Spectroscopic Instrument, known as DESI, have found growing hints that dark energy, ...

To turn that distance into a Hubble constant, you also need the event’s redshift, which is tied to how fast the source is receding due to cosmic expansion. Standard approaches get the redshift by ...

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 ...

Hubble’s measurements of today’s expansion rate do not match the rate that was expected based on how the Universe appeared shortly after the Big Bang over 13 billion years ago. Using new data from the ...
