A 'boom' of light that appears when a particle exceeds the speed of light set by a medium could, in other contexts, signal a kind of quantum instability that could trigger what's known as vacuum decay ...

Like stretch marks left on skin that expanded too quickly or cracks embedded in freezing ice, cosmic strings are artifacts of ...

As physicists search for a theory of quantum gravity, new results show that classical gravity can still interact with quantum fields to allow matter to become entangled. When you purchase through ...

In spring 2002, Chelsey Bryant Krug flew to Colorado in search of a job. She had just enrolled as a graduate student in aerospace engineering sciences at the University of Colorado Boulder. She found ...

Solar cells face significant challenges when deployed in outer space, where extremes in the environment decrease the efficiency and longevity they enjoy back on Earth. University of Toledo physicists ...

"Precision in these measurements is critical, as even subtle discrepancies could signal deviations from the model — potentially revealing new physics." When you purchase through links on our site, we ...

The head of the Trump administration's Golden Dome program says the technologies needed to create an ambitious space-based missile defense system are already in existence. U.S. Space Force General ...

Space plasma physics examines the behaviour of ionised gases in planetary and astrophysical environments where electromagnetic forces dominate over collisional interactions. This field explores ...

Five years after the collapse of the Arecibo Observatory telescope — the world’s largest single-dish radio telescope until 2016, when China completed a larger one — space physicist Qihou Zhou is ...

One of the most awkward parts of writing a book is that, eventually, authors have to ask people for “blurbs” – the endorsements that you see on the cover of a book, encouraging you to buy it. I am now ...

When scientists sent bacteria-infecting viruses to the International Space Station, the microbes did not behave the same way they do on Earth. In microgravity, infections still occurred, but both ...
