Our universe is known to be remarkably homogeneous and isotropic. This essentially means that matter is distributed evenly ...

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 University of Queensland researcher has developed a new mathematical model to explain the evolution of the universe which, for the first time, includes collapsing regions of matter and expanding ...

Earlier this year, Euclid—a European telescope tasked to create the largest 3D map of the universe—sent back troves of cosmic data from deep space. Astronomers have since been hard at work picking ...

Astronomers have observed a massive and extremely active barred spiral galaxy in the early Universe and found that it has important similarities and differences with modern galaxies. This improves our ...

A novel theory suggests that the current expansion rate of the universe is not fixed, but was in fact quite different in the early universe—and that the universe could start contracting at some point.

Scientists are shining a brighter light on dark matter thanks to a new high-resolution map, unveiling the invisible material that shapes everything we see. Using James Webb Space Telescope’s (JWST) ...

Preface : A meditation on the origins of science and the science of origins -- Overture : The greatest story ever told -- pt. 1. The origin of the universe. In the beginning -- Antimatter matters -- ...

A group of scientists, including a class of undergraduate students at the University of Chicago, has discovered the most chemically pristine star yet known in the universe. This star dates back to the ...
