How Physicists Measured the Rarest Event Ever Directly Observed

This past week, scientists announced that they’d made an incredible physics observation using a vat of liquid xenon. It’s officially the rarest nuclear decay—and really, the rarest event of any kind—ever directly measured. Read More >>

Dark Matter Detector Makes Incredible Neutrino Observation

A detector designed to hunt for dark matter has made a particle physics observation that will hopefully help physicists establish important truths about our Universe. No, it didn’t spot dark matter, but the new result proves that these ultra-sensitive detectors are valuable to scientists for multiple reasons. Read More >>

Fermilab Breaks Ground on a New Particle Accelerator to Solve the Mysteries of Neutrinos

Construction began last week on a new particle accelerator at Fermi National Accelerator Laboratory in the US. The new project will power Fermilab’s flagship neutrino-studying accelerator experiment. Read More >>

Scientists Weighed the Earth Using Ghostly Particles From Space

Scientists have to use some roundabout methods to weigh the Earth and measure what’s inside it—typically, they’ve used sound waves and the strength of gravity to make their calculations. But one team has weighed the Earth in a whole new way: by measuring mysterious cosmic particles that pass through it. Read More >>

Astronomers Propose Huge New Telescope System to Understand the Most Energetic Particles Ever Detected

Astronomers have proposed a truly enormous telescope consisting of 200,000 radio receivers around the world, which added together would cover an area the size of Nebraska. They hope to spot incredibly energetic but difficult to detect neutrinos coming from distant astrophysical sources. Read More >>

New Particle Could Explain ‘Unusual’ Antarctic Weather Balloon Detection

A weather balloon in Antarctica spotted what looked like a high-energy particle from outer space striking the ice back in 2006. Except the particle didn’t hit from above—it somehow travelled all the way through the planet. Eight years later, it happened again. Read More >>

See the South Pole Message That Alerted Astronomers to the Cosmic-Ray-Spewing Blazar

On Thursday, scientists made a huge announcement: Telescopes around the world recorded a source of mysterious, ultra-high-energy cosmic rays, the highest-energy particles that hit the Earth. It all started with a text message. Read More >>

Cosmic Ray Mystery Finally Cracked Thanks to Supermassive Black Hole Beaming Energy Straight at Earth

Every so often, protons and even entire atomic nuclei strike the Earth with extremely high energies—much higher than what scientists can produce in their most powerful physics experiments. Since the discovery of “cosmic rays” a hundred years ago, no one knew for sure where the most energetic of these particles came from—until now. Read More >>

Physicists Are Excited About Fresh Evidence for a New ‘Sterile’ Fundamental Particle

Neutrinos are ghostly, mysterious shape-shifters. New evidence bolsters the existence of an even ghostlier, “sterile” version of this strange particle. Read More >>

Shuttered Experiment Shares New View of Ghostly Neutrinos’ Shape-Shifting Behaviour

Can we take a minute to appreciate just how weird neutrinos are? The second most abundant known particle in the universe passes right through most regular matter like a ghost—you get hit with around a quadrillion of them from the Sun every second. Not only that, but neutrinos can even change between three different identities. They are spooky as hell. Read More >>

Ghost Particles Detected on Far Side of Earth Bolsters Crucial Physics Theory

If we’re ever going to truly understand how our Universe works, we’ll need to take lots of different measurements, but measuring can be one of science’s most difficult tasks. How, for example, do scientists measure an invisible thing that passes directly through solid matter without stopping? The inventions scientists come up with to make this possible are often truly incredible—even if the measurements made are totally expected. Read More >>

Scientists Are Getting Closer to Understanding Where All the Antimatter Has Gone

You and me, we’re matter. Everyone you know is matter. Everything on Earth, spare a few particles, is matter. Most of the things in space are matter. But we don’t have convincing reasons why there should be so much more matter than antimatter. So where’s all the antimatter? Read More >>

South Pole Experiment’s Hunt for Exotic Neutrino Comes Up Empty

It’s been a rough few weeks of null results for physicists. First, a promising underground experiment failed to find evidence of dark matter. Then news broke that the Large Hadron Collider hadn’t discovered an exciting new particle after all. Read More >>

Scientists at Fermilab Are About to Start Shooting Neutrinos Through the Earth

Fermilab outside Chicago will soon begin its Deep Underground Neutrino Experiment (DUNE), and what it hopes to accomplish is as brilliant and confusing as the book of its namesake. Read More >>
