A forthcoming upgrade to the IceCube detector will provide deeper insights into the elusive particles. Underneath the vast, frozen landscape of the South Pole lies IceCube, a gigantic observatory ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

Just over 40 years ago, a new theory about the early universe provided a way to tackle multiple cosmological conundrums at once. For Alan Guth, insight into the origins of the universe started in a ...

For decades scientists have tried to find a way to measure the mass of the lightest matter particle known to exist. Three new approaches now have a chance to succeed. In 1980, Hamish Robertson was a ...

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 ...

Over time, particle physics and astrophysics and computing have built upon one another’s successes. That coevolution continues today. In the mid-twentieth century, particle physicists were peering ...
