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 ...

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 ...

Once the most popular framework for physics beyond the Standard Model, supersymmetry is facing a reckoning—but many researchers are not giving up on it yet. The Standard Model of particle physics is ...

The average banana produces a particle of antimatter roughly once every 75 minutes. US-based scientists and students working on research and experiments with the Large Hadron Collider contribute to a ...

In 2023, the ALICE experiment was ready for their best year yet, until a mysterious signal threatened everything. As the LHC wraps up its 2025 lead-ion run, physicists recall how they worked together ...

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 ...

Documenting the work of building the world’s largest neutrino experiment presents photographers with a unique set of challenges. Discussing her decades-spanning career, photographer Annie Leibovitz ...

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 ...

In the 1900s, Albert Einstein unified the concepts of space and time, giving us a useful new way to picture the universe. At the start of the 20th century, physicists had a problem: The speed of light ...

In addition to revealing characteristics of mysterious particles called neutrinos, the massive DUNE experiment could help astronomers find a supernova right as it begins. At this very moment, ...

Not only are we made of fundamental particles, we also produce them and are constantly bombarded by them throughout the day. Fourteen billion years ago, when the hot, dense speck that was our universe ...

Neutrinos don’t seem to get their mass in the same way as other particles in the Standard Model. In 1998, researchers made a discovery that challenged their understanding of particle physics and ...
