Berkeley, CA — Weak gravitational lensing is a uniquely promising way to learn how much dark matter there is in the Universe and how its distribution has evolved since the distant past. New work by a ...

“The cosmological principle is like an ultimate kind of statement of humility,” explains James Adam, astrophysicist at the University of the Western Cape, Cape Town, South Africa, and lead author of ...

A series of recent observations is bringing the large-scale dark matter scaffolding of the cosmos into sharper observational focus, using techniques that range from gravitational lensing to radio ...

NSF–DOE Vera C. Rubin Observatory, funded by the US National Science Foundation and US Department of Energy's Office of Science, will add an unprecedented amount of cosmological data to the study of ...

Astronomers used subtle warps in galaxy shapes to map the invisible forces shaping the universe. By reanalyzing years of telescope images, they studied more than 100 million galaxies across an ...

In the leading model of cosmology, most of the universe is invisible: a combined 95 percent is made of dark matter and dark energy. Exactly what these dark components are remains a mystery, but they ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

Astronomy is, in essence, an exercise in inference. We cannot touch the stars, nor scoop up galaxies in a lab. Instead, we decipher the universe through its light — its color, intensity, rhythm and ...

It’s one of the most memorable moments of my career – and not in a good way. I was giving a talk to a room packed full of eminent astrophysicists, but there had been a bit of a childcare crisis, so ...
