Learn how Hubble is measuring the expansion rate of the Universe in this new explainer ... Kornmesser (ESA/Hubble) Dark Energy Expansion Graph Credit: NASA's Goddard Space Flight Center Dark ...

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 ...

Since the universe is still expanding, with each passing year a galaxy is a bit more distant, and that means its redshift should become slightly larger. In other words, cosmic expansion means that ...

New research suggests that dark energy isn't needed to explain the acceleration in the expansion of the universe — instead suggesting giant voids in space are creating an illusion. When you ...

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.

Now, results provide even stronger support to the faster rate of expansion. A new measurement confirms what previous -- and highly debated -- results had shown: The Universe is expanding faster ...

Determining the expansion rate of the universe—known as the Hubble constant—has been a major scientific pursuit ever since 1929, when Edwin Hubble first discovered that the universe was expanding.
