Let's set the record straight: NASA has not found a parallel universe. The claims making the rounds on social media are not ...
The Hubble tension is one of the most hotly debated discrepancies in all of astronomy. It centers around a number called the ...
It centers around the Hubble constant—the measurement of how fast our universe is expanding—which comes out as two different numbers when calculated two different ways, even though those ...
The rate at which the universe is expanding is expressed as a value called the Hubble Constant, generally abbreviated as “H 0 ...
The universe doesn't have an outer perimeter, and nothing exists outside it, because there isn't an outside. As an analogy, consider the shape of our galaxy, the Milky Way. We can infer that it is ...
For years, scientists have been troubled by an unusual feature of our universe. It appears to be expanding faster today than it did in the past – and researchers are not sure why. Now the Webb ...
From mass fluctuations, to Little Red Dots, to new galaxies captured by the James Webb telescope—astronomy has learned a lot ...
But from where Earth sits in the observable universe, our view extends more than 13 billion years into the past. Far outside our Local Group, astronomers have found galaxies so metal-poor and so ...
Hubble was right!' The largest cosmic survey from the James Webb Space Telescope indicates scientists may need another ...
"The discrepancy between the observed expansion rate of the universe and the predictions of the standard model suggests that our understanding of the universe may be incomplete. " New observations ...
