The Hubble tension is one of the most hotly debated discrepancies in all of astronomy. It centers around a number called the Hubble constant, which is functionally the rate at which our universe is ...

the Hubble constant. Modern science has made many strides in setting the historical record straight. In that tradition, we suggest the International Astronomical Union (IAU) formally rename the ...

The rate of expansion of the universe today is a figure known as the Hubble constant, which is typically measured in units of kilometers per second per megaparsec (km/s/Mpc), where a megaparsec ...

New research suggests that a troubling disparity in the rate of expansion of the universe, known as the Hubble constant, may arise from the fact Earth sits in a vast underdense region of the cosmos.

Prof. Wendy Freedman, one of world’s leading cosmologists, has been awarded the National Medal of Science, the country’s ...

Dark matter, thought to comprise about 27% of the universe, is a hypothesized form of matter that is invisible but is inferred to exist based on its gravitational effects on ordinary matter - stars, ...

New observations from the James Webb Space Telescope back up previous findings from the Hubble telescope that contradict theoretical predictions, suggesting the standard model theorists work from ...

The universe's expansion rate, a figure called the Hubble constant, is measured in kilometers per second per megaparsec, a distance equal to 3.26 million light-years. A light-year is the distance ...
