Through the lens of the Hubble and James Webb Space Telescopes, scientists are zeroing in on the Hubble Constant, a vital ...

Is it possible to understand the universe without understanding the largest structures that reside in it? In principle, not ...

This tells us that the velocity at which a galaxy is being carried away from us by the expansion of space is equal to its ...

For decades, scientists have worked to map the universe’s large-scale structure, testing cosmological models and ...

There's two main tactics for measuring the Hubble constant. One is directly, by observing 'standard candles' — that is, objects with predictable luminosities such as Cepheid variables ...

Quipu, Hercules, Serpens–Corona Borealis and Sculptor–Pegasus are all larger than the fifth and final superstructure ...

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.

Dark energy is still a mystery, but powerful new telescopes are set to uncover clues. With NASA and ESA leading the charge, ...

The rate of cosmic expansion is now known as the Hubble Constant. Ironically, Hubble himself never fully accepted the runaway universe as an interpretation of the redshift data. He suspected that ...
