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 ...
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 ...
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 ...
In the last decades, our understanding of the Universe has made tremendous progress. Not long ago, “precision astronomy” was thought to be an oxymoron. Nowadays, satellite experiments and powerful ...
Learn how Hubble is measuring the expansion rate of the Universe in this new explainer from NASA's Goddard Space Flight ...
Using known distances of 50 galaxies from Earth to refine calculations in Hubble's constant, astronomers estimates the age of the universe at 12.6 billion years. Using known distances of 50 galaxies ...

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.

Astronomers have proposed a new way to solve the so-called “Hubble tension,” but the approach ultimately raises more questions than it answers. By way of background, cosmologists are in a bit of a ...
