Learn how Hubble is measuring the expansion rate of the Universe in this new explainer from NASA's Goddard Space Flight ...
A novel theory suggests that the current expansion rate of the universe is not fixed, but was in fact quite different in the ...
The expansion rate, called the Hubble constant, ought to come out the same no matter how you measure it. Yet it does not. Measurements tied to the early universe, using relic signals like the cosmic ...
Our galaxy may reside in a billion-light-year-wide cosmic bubble that accelerates local expansion, potentially settling the long-running Hubble tension. Galaxy counts reveal a sparsely populated ...
