The Large Synoptic Survey Telescope will be named for an influential astronomer who left the field better than she found it. The Large Synoptic Survey Telescope, a flagship astronomy and astrophysics ...

Our best model of particle physics explains only about 5 percent of the universe. The Standard Model is a thing of beauty. It is the most rigorous theory of particle physics, incredibly precise and ...

A large and unexpected excess of top quark pairs has the physics community excited, but the interpretation is still up for debate. In 1995, Alexander Grohsjean cut out a story from the local German ...

The Planck scale sets the universe’s minimum limit, beyond which the laws of physics break. In the late 1890s, physicist Max Planck proposed a set of units to simplify the expression of physics laws.

Meet the world’s deepest underground physics facilities. A constant shower of energetic subatomic particles rains down on Earth’s surface. Born from cosmic ray interactions in the upper atmosphere, ...

The LHCb experiment at CERN has revealed a fundamental asymmetry in the behavior of particles called baryons. “The reason why it took longer to observe CP violation in baryons than in mesons is down ...

Three physicists share their experiences learning and communicating physics in a foreign language: English. Rose Ferreira, an astronomer and popular-science communicator who goes by the name Rose DF, ...

A possible explanation for the lightness of neutrinos could help answer some big questions about the universe. Mass is a fundamental property of matter, but there’s still a lot about it we don’t ...

Scientists around the world are testing ways to further boost the power of particle accelerators while drastically shrinking their size. At least when it comes to particle accelerators, bigger is ...

The fundamental particle of light is both ordinary and full of surprises. What physicists refer to as photons, other people might just call light. As quanta of light, photons are the smallest possible ...

Perplexed by gravity? Don’t let it get you down. Gravity: we barely ever think about it, at least until we slip on ice or stumble on the stairs. To many ancient thinkers, gravity wasn’t even a ...

Matter and antimatter behave differently. Scientists hope that investigating how might someday explain why we exist. One of the great puzzles for scientists is why there is more matter than antimatter ...
