Cold hydrogen clouds discovered inside superheated Fermi bubbles at Milky Way's center

Image
Researchers have found clouds of cold gas embedded deep within larger, superheated gas clouds or Fermi bubbles at the Milky Way's center . The finding challenges current models of Fermi bubble formation and reveals that the bubbles are much younger than previously estimated. "The Fermi bubbles are enormous structures of hot gas that extend above and below the disk of the Milky Way, reaching about 25,000 light years in each direction from the galaxy's center spanning a total height of 50,000 light years." "Fermi bubbles are a relatively recent discovery they were first identified by telescopes that 'see' gamma rays in 2010 there are different theories about how it happened, but we do know that it was an extremely sudden and violent event, like a volcanic eruption but on a massive scale." Bordoloi and the research team used the U.S. National Science Foundation Green Bank Telescope (NSF GBT) to observe the Fermi bubbles and get high-resolution data abo...

Galaxies Had a “Thick Phase” – JWST Just Revealed How They Slimmed Down

Image
The James Webb Space Telescope has given astronomers a stunning new window into the history of galaxies like our own Milky Way. By analyzing 111 edge-on galaxies, researchers discovered that galaxies form in two main stages: an early, chaotic thick disk followed by a calmer, thin disk that forms inside it. This pattern was observed even in galaxies 10 billion light-years away. The findings suggest that our Milky Way’s layered structure isn’t unique but part of a broader galactic trend, offering new insight into how galaxies evolve, build stars, and possibly even shape life-sustaining elements like oxygen and carbon. Disk Galaxies and Their Fossil Records Many galaxies, including our own Milky Way, have a remarkable structure: a flat, spinning disk made of stars. These stellar disks typically come in two main parts. The thin disk is home to younger stars rich in heavy elements like oxygen and carbon, while the thick disk holds older, more primitive stars. These distinct components act l...

Small, room-temperature quantum computers that use light on the horizon after breakthrough, scientists say

Image
Scientists say they’ve cracked a key challenge in scalable quantum hardware after generating an error-correcting, light-based qubit on a chip for the first time. Scientists have demonstrated that a photonic qubit a quantum bit powered by a particle of light can detect and correct its own errors while running at room temperature. They say it is a foundational step toward scalable quantum processors. In a new study published June 4 in the journal Nature, researchers at Canadian quantum computing startup Xanadu created a so-called "Gottesman–Kitaev–Preskill" (GKP) state directly on a silicon chip. GKP states are a type of quantum state that spreads information across multiple photons in a pattern that enables small errors to be spotted and corrected. This means that each qubit is capable of correcting itself, without needing to be bundled into large arrays of redundant qubits  a common requirement in today’s error-correction methods. It marks the first time this type of erro...

Physicists Close In on the Fifth Force That Could Unlock the Mystery of Dark Matter

Image
Scientists are using trapped ions in cutting-edge experiments to hunt for signs of an undiscovered particle that might help unravel the mystery of dark matter. The Standard Model of particle physics offers an exceptionally precise description of the fundamental components that form all visible matter, including the particles that make up everything around us and ourselves. It also defines the basic forces that govern interactions between these elementary particles. “The Standard Model is currently the best explanation of the universe, but we know it cannot explain everything,” says Diana Prado Lopes Aude Craik, Physics Professor at ETH Zurich. She points to dark matter as an example of “one of the biggest mysteries in physics today.” Observations from astronomy indicate that the visible matter we can detect does not fully account for the way galaxies spin. Because of this, physicists believe that the majority of the universe’s mass is made up of an unknown type of matter. This has led...

Physicists Unlock New Path to Weighing the Universe’s “Ghost Particle”

Image
Silver-110’s decay reveals a promising path to measure antineutrino mass. New data could reshape future neutrino studies. Neutrinos and antineutrinos are fundamental particles that possess mass, although their exact value remains unknown. Recent high-precision atomic mass measurements carried out at the Accelerator Laboratory of the University of Jyväskylä in Finland suggest that the beta decay of the silver-110 isomer could serve as a promising method for determining the mass of the electron antineutrino. This finding marks a significant advancement toward future experiments focused on measuring antineutrino mass. The question of how much mass neutrinos and antineutrinos have is one of the major unresolved issues in modern physics. As particles included in the Standard Model, neutrinos are found throughout the universe. They are generated in vast numbers by processes such as nuclear reactions in the Sun, with trillions of them passing through our bodies every second. A path to unders...

Scientists Achieve Teleportation Between Quantum Computers for the First Time Ever

Image
Oxford researchers have made a groundbreaking leap in quantum computing by successfully teleporting qubits between separate quantum processors. In a groundbreaking achievement, researchers at Oxford University have successfully demonstrated quantum teleportation between quantum computers, a feat that was previously confined to theoretical discussions and early-stage experiments. The team, led by physicist Dougal Main, managed to create a functioning logic gate between two quantum processors located about six feet apart. This represents a significant advancement in quantum computing, opening new possibilities for quantum networks and the realization of scalable quantum systems. Quantum Teleportation: A New Approach to Quantum Computing Quantum teleportation is a process where the state of a qubit an essential element of quantum computing is transferred from one qubit to another, without physically moving the particle itself. This unique phenomenon relies on quantum entanglement, which...

Physicist Solves 120-Year-Old Thermodynamics Puzzle and Corrects Einstein

Image
The paper argues that the third principle of thermodynamics follows from the second principle, rather than being a separate or independent concept. Professor José María Martín-Olalla of the University of Seville has published a paper addressing a thermodynamics problem that has remained unresolved for 120 years. In doing so, he corrects an idea proposed by Albert Einstein more than a century ago. The paper links Nernst’s theorem, an experimental observation from 1905 stating that entropy exchanges approach zero as temperature approaches zero, directly to the second principle of thermodynamics. Published in The European Physical Journal Plus, the study extends the implications of the second principle, which states that entropy in the universe tends to increase. The historical problem of absolute zero The problem surrounding Nernst’s theorem emerged in the early 20th century, during investigations into how matter behaves at temperatures near absolute zero (minus 273 degrees Celsius).
