To astronomers in the 1990s, these three facts were self-evident: The universe is expanding; all the matter in the universe is gravitationally attracting all the other matter in the universe; ...

A new study probing the structure and evolution of galaxy clusters shows good agreement with the predictions of standard cosmological models. Cosmologists have found new evidence for the standard ...

With a focus on experimental astrophysics, the Zemcov Research Group is involved in several projects in a variety of roles, ranging from technology development to the scientific interpretation of data ...

The Big Bang wasn’t always a sure bet. For several decades in the 20th century, researchers wrestled with interpreting cosmic origins, or if there even was a beginning at all. At the forefront of that ...

New observations from the James Webb Space Telescope suggest that a new feature in the universe—not a flaw in telescope measurements—may be behind the decadelong mystery of why the universe is ...

Penrose's idea of a conformal cyclic cosmology hypothesizes that our Universe arose from a pre-existing Universe that would leave imprints on our cosmos today. This is a fascinating and imaginative ...

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. When you ...

A researcher has made a puzzling discovery while analyzing observations taken by NASA’s James Webb Space Telescope. While analyzing images for the telescope’s Advanced Deep Extragalactic Survey (JADES ...

The James Webb Space Telescope, not even finished with its first full year of observations, has delivered some real stunners. But amid the breathtaking images and unprecedented findings, there was a ...
