"The KBC supervoid is a region that is about 20% less dense than the cosmic average, centered roughly where we are and extending out to about a billion light years," Banik said. "Typically, when ...

The Hubble tension is one of the most hotly debated discrepancies in all of astronomy. It centers around a number called the Hubble constant, which is functionally the rate at which our universe is ...

A controversial new theory is presenting challenges to the long-theorized existence of mysterious dark energy throughout our ...

The rate of expansion of the universe today is a figure known as the Hubble constant, which is typically measured in units of kilometers per second per megaparsec (km/s/Mpc), where a megaparsec (Mpc) ...

Now, to the dismay of researchers, a new study designed to double-check the calculated rate of the universe's expansion – ...

The James Webb space telescope had several stunning findings this year that changed how we understand the universe.

Just how long has the universe been around? Scientists estimate the universe is 13.8 billion years old, with an uncertainty ...

Known as the Hubble tension, the discrepancy remains unexplained even by the best cosmology models. "The discrepancy between the observed expansion rate of the universe and the predictions of the ...

A new study in published in Physical Review Letters analyzes the most complete set of galaxy clustering data to test the ΛCDM ...

The discrepancy is called the Hubble Tension. The observations by Webb, the most capable space telescope ever deployed, appear to rule out the notion that the data from its forerunner Hubble was ...

employing both Webb and Hubble to show that the so-called Hubble Tension may be real. If that's true, the missing piece of the puzzle could be profound indeed. For decades after astronomers came ...
