Black hole 'bullets' fired at Mars could reveal more about dark matter

Tiny black hole "bullets" left over from the Big Bang could be passing through Mars at speeds in excess of 7,000 times the speed of sound, causing the Red Planet to "wobble."

Astronomers can’t agree on how fast the universe is expanding. New approaches are aiming to break the impasse

It is almost 100 years since scientists discovered the universe is expanding. In the decades that followed, the accuracy of the measurements, and interpretations and implications of this discovery, were a source of fierce debate. We now know the universe emerged dramatically from a highly compressed state in an event…

James Webb telescope confirms the earliest galaxy in the universe is bursting with way more stars than we thought possible

The light from the most distant galaxy in the known universe suggests that there's something off about our current cosmological models, a new James Webb Space Telescope study finds. The explanations remain elusive.

The Higgs particle could have ended the universe by now – here’s why we’re still here

Although our universe may seem stable, having existed for a whopping 13.7 billion years, several experiments suggest that it is at risk – walking on the edge of a very dangerous cliff. And it’s all down to the instability of a single fundamental particle: the Higgs boson.

Can the James Webb Space Telescope see galaxies over the universe's horizon?

The James Webb Space Telescope has revolutionized astronomy in just two years of operations, but how can it see a galaxy 33.8 billion light-years away in a universe that is only 13.8 billion years old?
