NASA has released a huge new report that astronomers are calling Hubble’s magnum opus. Analyzing 30 years of data from the famous space telescope, the new study makes the most precise measurement yet ...

A striking reality faces modern cosmology: two of the most advanced telescopes ever built now agree on a result that the standard cosmological model cannot explain. Webb’s confirmation of the Hubble ...

NASA announced Thursday that its Hubble Space Telescope (HST) has calibrated more than 40 "milepost markers" of space and time. The mile markers help scientists measure the expansion rate of the ...

Until just a century ago, our galaxy was thought to be the lone family of stars occupying the Cosmos. Philosophers, notably Immanuel Kant in the 18th Century, postulated the existence of other ...

Last time I wrote about new data that overturns the standard cosmological model. Before anyone starts dusting off their ...

Pasadena, CA— In the early part of the 20th Century, Carnegie astronomer Edwin Hubble discovered that the universe is expanding. The rate of expansion is known as the Hubble constant. Its precise ...

Astronomers have been arguing about the rate of the universe’s expansion for nearly a century. A new independent method to measure that rate could help cast the deciding vote. For the first time, ...

The Hubble Space Telescope might be best known by the public for the beautiful images of space it captures, but it is most famous among astronomers for producing groundbreaking insights into the ...

The rate of the universe’s expansion has vexed astronomers for decades. Called the Hubble constant, the figure is quite different depending on how you get to it—fittingly, a source of constant ...

The question of how fast the universe is expanding continues to confound scientists. Although it might seem like a fairly straightforward issue, the reality is that it has been perplexing the best ...

Whatever dark energy is, explanations for it have less wiggle room following a Hubble Space Telescope observation that has refined the measurement of the universe’s ...
