Northrop Grumman has written a new line in the history books, the company's Mission Extension Vehicle 1 (MEV-1) executing the first undocking of two commercial satellites in geosynchronous earth orbit (GEO) – heralding a new age of commercial space operations.

In just the first 259 days of data collection, KATRIN, a beta-decay-based detector in Germany, has set the smallest upper limit yet on the mass of the neutrino—the universe's lightest massive particle

No, it is not the Larger Hadron Collider. It's the Future Circular Collider.

Supersymmetry, long considered the golden child of theoretical physics, has officially lost its luster at the world's reigning particle accelerator

The Earth sits inside a 300 pc-wide void that was carved by a series of supernova explosions that went off tens of millions of years ago, pushing away interstellar gas and creating a bubble-like structure. The 60 Fe peak deposits found in the deep-sea crust have been interpreted by the imprints left by the ejecta of supernova explosions occurring about 2–3 and 5–6 Myr ago. It is likely that the 60 Fe peak at about…

The device was only half-finished at the time. Imagine its full potential.

A "ghost particle" discovered by a detector in the Mediterranean carried 30 times more energy than any neutrino observed to date

Most powerful cosmic radiation ever detected approaches Earth. Atmosphere shields planet from 40 trillion electron volt particles.

Axion dark matter should be produced and converted to gamma rays during a supernova. Will we be lucky enough to see them?

MIT assistant professor of nuclear science and engineering Ethan Peterson is addressing some of the practical, overlooked issues that need to be worked out for viable fusion power plants, including neutron transfer and the handling of neutrons produced in the fusion reaction.

The newly-discovered isotope, plutonium-227, has a half-life of 0.78 seconds, according to a team of physicists from China.

After decades of work, physicists have finally broken into the atom to build the first nuclear clock

The Large High Altitude Air Shower Observatory (LHAASO) officially released the precise measurements of high-energy gamma radiation from the W51 complex, confirming it as a cosmic-ray accelerator boosting particles up to so-called ultra-high energies (UHE, above 1014 electronvolts). The results also provide key evidence about the cosmic-ray acceleration limit in this complex.

Dark matter has turned out to be more elusive than physicists had hoped

The Large Hadron Collider (LHC) is the largest, most powerful particle accelerator ever built on Earth. Accelerating protons up to energies of ~7 TeV apiece — to energies about 7000 times greater…

Right now, the Large Hadron Collider (LHC) is the most powerful particle accelerator/collider ever built. Accelerating protons up to 299,792,455 m/s, just 3 m/s shy of the speed of light, they smash…

Chance that first detected emission line is a noise fluctuation is one in half a billion.

Quantum electrodynamics (QED) atoms are composed of unstructured and point-like lepton pairs bound together by the electromagnetic force.

Interface engineering has been proven to be effective in discovering new quantum states, such as topological states, superconductivity, charge density waves, magnetism, etc., which require atomic-scale heterostructure fabrication. Monolayer FeSe on SrTiO3 substrates has attracted intense interest owing to its remarkable interface-enhanced superconductivity.

Last week, at the annual Rencontres de Moriond conference, the CMS collaboration presented a measurement of the effective leptonic electroweak mixing angle. The result is the most precise measurement performed at a hadron collider to date and is in good agreement with the prediction from the Standard Model.
