Why is the universe expanding at an ever-increasing rate? This is one of the most exciting yet unresolved questions in modern ...

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 ...

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 ...

A new study led by University of Minnesota astrophysicists shows that high-energy light from small galaxies may have played a key role in the early evolution of the Universe. The research gives ...

Researchers from the Flatiron Institute and collaborators have developed an innovative method that uses artificial intelligence (AI) to estimate the universe's cosmological parameters with ...

A new suggestion that complexity increases over time, not just in living organisms but in the nonliving world, promises to rewrite notions of time and evolution. In 1950 the Italian physicist Enrico ...

NASA and the European Space Agency have released an image captured by the Hubble Space Telescope of a dwarf irregular galaxy that they admit looked "unexciting" at first glance. However, there's more ...

Published in Physics Letters B, the study provides a new perspective for exploring the evolution of matter in the early universe. About 13.8 billion years ago, within a millionth of a second after the ...
