Made from over 1,100 images captured by NSF-DOE Vera C. Rubin Observatory, the video begins with a close-up of two galaxies then zooms out to reveal about 10 million galaxies. Those 10 million ...

Yesterday, at the annual Rencontres de Moriond conference taking place in La Thuile, Italy, the LHCb collaboration at CERN reported a new milestone in our understanding of the subtle yet profound ...

The Standard Model of particle physics is both fantastically successful and glaringly incomplete. Its predictions have pieced together many of the known features of the universe and guided physicists ...

The particles we meet The radioactivity born inside your body is only a fraction of the radiation you naturally (and harmlessly) come in contact with on an everyday basis. The average American ...

The hidden neutrino As we experimentally observe them now, neutrinos cannot interact with the Higgs field because they’re are missing something vital: They are not right-handed. Particles can be ...

Neutrinos are some of the most abundant particles in the universe, and they are everywhere. Every second, more than 6 trillion neutrinos cruise in between the molecules of water and caffeine in your ...

What physicists refer to as photons, other people might just call light. As quanta of light, photons are the smallest possible packets of electromagnetic energy. If you are reading this article on a ...

The particle zoo expands By the start of the 1940s, it seemed like physicists were getting a handle on the fundamental particles and their interactions. They knew about electrons, protons and neutrons ...

Getting there Before building the DUNE detectors, scientists must test and validate their technology. Scientists at European research center CERN have taken on this task by building and operating a ...

Rethinking SUSY The Standard Model is our best framework for understanding the universe at the subatomic level. First developed in the 1960s, it has been tried and tested countless times, and it has ...

Mass is a fundamental property of matter, but there’s still a lot about it we don’t understand—especially when it comes to the strangely tiny masses of neutrinos. An idea called the seesaw mechanism ...
