The Atacama Cosmology Telescope in Chile has released its final batch of data after 15 years — and it proves that the Hubble ...

IN ARIZONA, AT Kitt Peak National Observatory, a telescope has spent three years building a three-dimensional map of the heavens. In examining the light from tens of millions of galaxies, the Dark ...

Light from distant galaxies reveals important information about the nature of the universe and allows scientists to develop high-precision models of the history, evolution and structure of the cosmos.

Astronomers have been confounded by recent evidence that the universe expanded at different rates throughout its life. New findings risk turning the tension into a crisis, scientists say. When you ...

The universe is undergoing an accelerated expansion, but the rate of that expansion has been a very controversial topic over the last few years. Different methods suggest slightly different numbers.

Scientists are baffled by a recent James Webb discovery. The discovery in question is detailed in a new study published in Nature. It details observations of a galaxy known as ZF-UDS-7329, which is ...

The current theoretical model for the composition of the universe is that it's made of normal matter, dark energy and dark matter. A new University of Ottawa study challenges this. A study, published ...

For measuring curvature of 3D (hyper) surface we need solid angles instead of plane angles. General relativity (GR), which explains events on the greatest cosmological scale, and quantum mechanics (QM ...

We see countless stars and galaxies sparkling in the universe today, but how much matter is actually there? The question is simple enough — its answer, however, is turning out to be quite a ...
