Our understanding of the true nature of the cosmos relies on measurements of its expansion, but cosmologists have been ...

For much of the twentieth century, scientists expected the expanding universe to slow over time. The opposite turned out to ...

Scientists are testing a novel way to measure cosmic expansion using time delays in gravitationally lensed quasars. Their ...

NASA has released a huge new report that astronomers are calling Hubble’s magnum opus. Analyzing 30 years of data from the famous space telescope, the new study makes the most precise measurement yet ...

The Hubble Space Telescope might be best known by the public for the beautiful images of space it captures, but it is most famous among astronomers for producing groundbreaking insights into the ...

Until just a century ago, our galaxy was thought to be the lone family of stars occupying the Cosmos. Philosophers, notably Immanuel Kant in the 18th Century, postulated the existence of other ...

With the combined power of two space telescopes, astronomers have made the most precise measurement to date of the Hubble Constant, the rate at which the universe is expanding. But the results provide ...

To many cosmologists, the best thing about neutron-star mergers is that these events scream into space an otherwise close-kept secret of the universe. Scientists combined the gravitational and ...

A team of astronomers using a variety of ground and space-based telescopes including the W. M. Keck Observatory on Maunakea, Hawaiʻi Island, have made one of the most precise independent measurements ...
