Animation of the findings by researchers who used time-delay cosmography to independently confirm that the universe’s current ...

Astronomers are closing in on a result so statistically secure that, in their language, it borders on certainty: a 99.9999999 ...

NASA’s Hubble Space Telescope has made a significant breakthrough in the field of astronomy by refining the age of the Methuselah Star, also known as HD 140283. This star, first identified in 1908, ...

Keck Observatory reports that spectroscopy from its Keck Cosmic Web Imager, combined with data from NASA’s James Webb and ...

Current physics is speeding toward a breaking point, as astronomers confirm that the Hubble tension in new data.

New gravitational lensing measurements by the TDCOSMO Collaboration support the Hubble Tension, confirming differences between Early and Late Universe Hubble Constant values using updated ...

The new study used the known distance to a galaxy called M106/NGC 4258 — a spiral galaxy in the constellation Canes Venatici — as a reference point. The universe is expanding faster than astronomers ...

New measurements using gravitational lensing suggest the universe’s current expansion rate does not agree with signals from ...

For the past decade, scientists have been trying to get to the bottom of what seemed like a major inconsistency in the universe. The universe expands over time, but how fast it’s expanding seemed to ...

"The discrepancy between the observed expansion rate of the universe and the predictions of the standard model suggests that our understanding of the universe may be incomplete. " When you purchase ...

For humans, the most important star in the universe is our Sun. The second-most important star is nestled inside the Andromeda galaxy. Don't go looking for it -- the flickering star is 2.2 million ...

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 ...
