Our galaxy may reside in a billion-light-year-wide cosmic bubble that accelerates local expansion, potentially settling the ...

For one, scientists observe a "cosmic fossil" called the cosmic microwave background (CMB). The first light that was free to ...

From this work, the Hubble constant that the team calculated was 73 km/s/Mpc (45.4 miles), give or take just 1 km/s/Mpc (0.6 miles). That brings the uncertainty down to just 1.4 percent, far more ...

Measurements of the Hubble constant — the Universe's expansion rate — depends on where you look. A new study weighs in on one of science's great questions.

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 ...

Since 1929, scientists have known that the universe is expanding at a rate dictated by the so-called Hubble constant, or H 0, named after U.S. astronomer Edwin Hubble.He and his colleagues ...

This Hubble Telescope image shows a doubly-imaged quasar, which can be used to measure the Hubble constant. A new technique of measuring the Hubble Constant from such doubly-imaged quasar systems ...

More than 90 years ago, astronomer Edwin Hubble observed the first hint of the rate at which the universe expands, called the Hubble constant.

Day three brought two new measurements of the Hubble constant: A cosmic distance ladder calibrated with “Mira” stars gave 73.6, and galactic surface brightness fluctuations gave 76.5, both ...
