The idea that the universe is expanding was first proposed by Edwin Hubble in the late 1920s and has been repeatedly backed ...

The "theory method" gives a value for the Hubble constant of about 152,000 miles per hour per megaparsec (68 kilometers per second per megaparsec, or Mpc), ...

This new round of measurements from the JWST seems to cement the idea that that there’s something wrong with the theory.Able to basically re-run Hubble’s observations with a higher resolution ...

Astro Brief is a collaboration between KSMU, the Missouri Space Grant, and MSU's Department of Physics, Astronomy and ...

In recent years, trouble has been brewing in attempts to measure the universe's expansion, which is governed by the Hubble–Lemaître law.This tells us that the velocity at which a galaxy is ...

The original version of this story appeared in Quanta Magazine. Nearly a century ago, Edwin Hubble discovered that the universe is getting larger. Modern measurements of how fast it is expanding ...

Now, a new theory that suggests our galaxy could be surrounded by a void could help better explain the acceleration, and some are calling it a “Hubble Bubble.” ...

The Hubble constant is one of the most important numbers in cosmology because it tells us how fast the universe is expanding, which can be used to determine the age of the universe and its history. It ...

A new theory of quantum gravity, which attempts to unite quantum physics with Einstein's relativity, could help solve the puzzle of the universe's expansion, a theoretical paper suggests.

A strange phenomenon on Saturn’s rings can only be spotted during its equinox. For the first time in 15 years, it’s back. And scientists are hoping Hubble can finally unlock the mystery.

IN 1936, Einstein predicted a cosmic optical illusion — but he thought we'd never be able to see it. Since, astronomers have bore witness to several of these rare tricks.
