The expansion of the Universe is not constant. Recent measurements have shown that the rate of the Universe's expansion is increasing. The evidence for this area of physics comes from observations ...

The latest findings, published in The Astrophysical Journal on December 9, offer a high-precision measurement of the Hubble constant. And these numbers, as precise as they are, just don’t line ...

Building on earlier data from the Hubble Space Telescope, it confirms that unknown forces are driving the universe’s accelerated expansion. It means there's a glaring gap in what astronomers ...

The motion of objects can be analysed using equations and graphs. These tools allow ... radiation as evidence for the Big Bang and expansion of the Universe.

The expansion of the universe is, in some ways, similar. But this analogy gets one thing wrong – while the dough expands into the baking pan, the universe doesn’t have anything to expand into.

Two years of data from NASA's James Webb Space Telescope have now validated the Hubble Space Telescope's earlier finding that the rate of the universe's expansion is faster - by about 8% - than ...

Physicists have been puzzling over conflicting observational results pertaining to the accelerating expansion rate of our Universe—a major discovery recognized by the 2011 Nobel Prize in Physics.

JWST measured the distances between stars and galaxies, which confirmed earlier measurements made by the Hubble Space Telescope. "The discrepancy between the observed expansion rate of the universe ...
