A new three-volume study explores how quantum physics, gravitation and cosmology may be understood within a unified ...

A unique technique allowed astronomers to see the early universe as a "sea of light" and explore the effects of gravity and ...

A new study has estimated the universe’s possible age by using precise data on stars.

The discovery of the universe’s oldest stars, identified within our own Milky Way galaxy, marks a significant leap forward in our understanding of cosmic history. These ancient stars, formed shortly ...

A systematic search for the first bright galaxies to form in the early universe has revealed a dramatic jump in the number of such galaxies around 13 billion years ago. These observations of the ...

"Birth of the Universe" at Manfred Olson Planetarium will explore clues that astronomers have used to understand the evolution of the universe. Scientists trace the origins of the cosmos to the Big ...

The plot represents the new model with the x-axis and the y-axis showing the minimum sizes of collapsing and expanding regions that can impact cosmological measurements. The contours are independent ...

Astronomers tallying up all the normal matter—stars, galaxies and gas—in the universe today have come up embarrassingly short of the total matter produced in the Big Bang 13.6 billion years ago. In ...

Physicists who work with a concept called string theory envision our universe as an eerie place with at least nine spatial dimensions, six of them hidden from us, perhaps curled up in some way so they ...
