Research suggests that the germanium isotope really does have a half-life of 11 days

by

Relevant parts of the spectra obtained on day 20 from the three measurements performed. Credit: Physical assessment C (2024). DOI: 10.1103/PhysRevC.109.055501 The search for the elusive neutrino takes many forms. Detectors consisting of many tons of gallium are used in various experiments because neutrino interactions can occur on the stable gallium-71 (71Ga) nucleus and transform … Read more

Towards testing the quantum behavior of gravity: a photonic quantum simulation

by

Artist’s representation of the implemented photonic experiment in which entanglement between the polarizations of individual photons is mediated by the independent degree of freedom of the photon path. In particular, mediated entanglement represents a core principle of future experiments with massive particles, aiming to explore the quantumness of gravity for the first time.

Martian meteorites found on Earth provide unprecedented insight into the Red Planet

by

Chassigny meteorite in cross-polarized light – Scripps Institution of Oceanography at UC San Diego When a meteorite hit Mars eleven million years ago, pieces of the Red Planet flew into space – and some of them landed on Earth in the form of meteorites, providing unprecedented evidence about the planet’s composition. Now scientists at UC … Read more

The hunt for ultralight dark matter

by

If or when SLAC’s planned project, the Light Dark Matter Experiment (LDMX), receives funding — a decision from the Department of Energy is expected within about a year — it will scan for light, dark matter. The experiment is designed to accelerate electrons toward a target made of tungsten in terminal A. In the vast … Read more

Webb telescope once again finds the most distant galaxy ever observed

by

The galaxy JADES-GS-z14-0, as seen by the James Webb Space Telescope, existed 290 million years after the Big Bang. The James Webb Space Telescope has discovered what appears to be a new record holder for the farthest known galaxy, a remarkably bright galaxy that existed just 290 million years after the Big Bang, NASA said … Read more

How galaxies grew in the early universe

by

JWST recently caught three of the earliest galaxies in the universe as they were contracting from a giant, dark cloud of hydrogen gas. The three faint spots of red light in a recent set of JWST data traveled more than 13 billion light-years through space to reach the telescope’s mirrors. That ancient light provides a … Read more

Did galaxies or supermassive black holes form first? – Interesting technology

by

Galaxies consist of various astronomical objects, including black holes, planets and stars. At the core of a galaxy lies a supermassive black hole (SMBH), one of the most powerful and dangerous entities in the universe. A puzzling question for scientists was whether SMBHs produced galaxies or whether galaxies formed SMBHs. Events in the early universe … Read more

Combining theory and experiment to shed new light on proton spin

by

A global analysis of experimental data and Quantum Chromodynamics calculations of the lattice provides insight into the role of the gluons (purple coils) that contribute to the spin of the nucleon. Gluons are manifestations of the. Credit: Jefferson Lab Nuclear physicists have long been working to reveal how the proton gets its spin. Now, a … Read more
