Learn how Hubble is measuring the expansion rate of the Universe in this new explainer from NASA's Goddard Space Flight ...
Two ways of measuring how fast the universe is expanding disagree, a puzzle known as the Hubble tension. Tiny magnetic fields from the Big Bang may offer a solution.
The Hubble Space Telescope, a cornerstone of modern astronomy, has been providing breathtaking images and invaluable data for over three decades. As a collaboration between NASA and the European Space ...
Scientists are testing a novel way to measure cosmic expansion using time delays in gravitationally lensed quasars. Their results match “local” measurements but clash with early-universe estimates, ...
For decades, astronomers have been trying to nail down the value of the Hubble constant—a measure of how fast the universe is expanding. But some cosmologists say there’s evidence that the universe is ...
The venerable Hubble observatory is going strong despite its decades in space and the advent of next-generation successors ...
Adam Riess was 27 years old when he began the work that earned him the Nobel Prize in Physics, and just 41 when he received it. Earlier this year, Riess, who is now 55, pulled a graph-paper notebook ...
A Simon Fraser University cosmologist believes his team’s new research may bring them a step closer to cracking one of science’s biggest questions – the Hubble tension. The quest to determine how fast ...
