Astronomers have made new measurements of the Hubble Constant, a measure of how quickly the Universe is expanding, by combining data from the Hubble Space Telescope and the James Webb Space Telescope.

Planck's constant is one of the fundamental constants that sets up all the "rules" for how things work in our universe. (It’s named after the theoretical physicist Max Planck, who is best known for ...

A discrepancy between different measurements of the Hubble constant makes scientists question whether something is amiss in our understanding of the universe. Few numbers have gotten under astronomers ...

From the moment it burst into existence more than 13 billion years ago, the universe has been expanding, with galaxies visibly flying apart from each other. To make sense of the physical laws ...

Using known distances of 50 galaxies from Earth to refine calculations in Hubble's constant, a research team led by a University of Oregon astronomer estimates the age of the universe at 12.6 billion ...

Researchers have redetermined the gravitational constant G using a new measurement technique. Although there is still a large degree of uncertainty regarding this value, the new method offers great ...
