Rosetta spacecraft detects unexpected ultraviolet aurora at a comet

Posted by in categories: particle physics, space

Data from Southwest Research Institute-led instruments aboard ESA’s Rosetta spacecraft have helped reveal auroral emissions in the far ultraviolet around a comet for the first time.

At Earth, auroras are formed when charged particles from the Sun follow our planet’s to the north and south poles. There, solar particles strike atoms and molecules in Earth’s atmosphere, creating shimmering curtains of colorful light in high-latitude skies. Similar phenomena have been seen at various planets and moons in our and even around a distant star. SwRI’s instruments, the Alice far-ultraviolet (FUV) spectrograph and the Ion and Electron Sensor (IES), aided in detecting these novel phenomena at 67P/Churyumov-Gerasimenko (67P/C-G).

“Charged particles from the Sun streaming towards the comet in the solar wind interact with the gas surrounding the comet’s icy, dusty nucleus and create the auroras,” said SwRI Vice President Dr. Jim Burch who leads IES. “The IES instrument detected the electrons that caused the aurora.”

To Make Fairer AI, Physicists Peer Inside Its Black Box

How One Irreverent Physicist Went From Levitating Frogs to Winning the Nobel Prize

Posted by in categories: materials, particle physics

The following is adapted from Lewis’ The Rise: Creativity, the Gift of Failure, and the Search for Mastery, published by Simon & Schuster.

“It says, ‘No entrance,’ but you just enter,” physicist Andre Geim told me about the graphite mines in the mountains where he often hikes. His comment embodied the insouciance behind his Nobel Prize–winning physics experiment and his habit of experimenting deliberately outside of his area of expertise.

First experimental evidence of a new type of dark boson possibly found

Posted by in categories: cosmology, particle physics

It prevents galaxies from flying apart.


Two experiments hunting for a whisper of a particle that prevents whole galaxies from flying apart recently published some contradictory results. One came up empty handed, while the other gives us every reason to keep on searching.

Dark bosons are dark matter candidates based on force-carrying particles that don’t really pack much force.

NASA Found Another Way Into Nuclear Fusion

Posted by in categories: nuclear energy, particle physics, space

O,.o.


NASA has unlocked nuclear fusion on a tiny scale, with a phenomenon called lattice confinement fusion that takes place in the narrow channels between atoms. In the reaction, the common nuclear fuel deuterium gets trapped in the “empty” atomic space in a solid metal. What results is a Goldilocks effect that’s neither supercooled nor superheated, but where atoms reach fusion-level energy.

The Universal Mind Revealed as a Multi-Layered Quantum Neural Network

Posted by in categories: mathematics, particle physics, quantum physics, robotics/AI

In the sixties of the previous century, the science of Cybernetics emerged, which its founder Norbert Wiener defined as “the scientific study of control and communication in the animal and the machine.” Whereas the cyberneticists perhaps saw everything in the organic world too much as a machine type of regulatory network, the paradigm swapped to its mirror image, wherein everything in the natural world became seen as an organic neural network. Indeed, self-regulating networks appear to be ubiquitous: From the subatomic organization of atoms to the atomic organization of molecules, macromolecules, cells and organisms, everywhere the equivalent of neural networks appears to be present.

A Quantum Molecular Assembler

Posted by in categories: chemistry, computing, particle physics, quantum physics

Researchers have created a molecule in a single, precisely characterized quantum state by merging two carefully prepared atoms.

Researchers have demonstrated a quantum molecular assembler—a device that takes individual atoms as inputs and merges them into a molecule in a desired quantum state. The team used lasers to trap and cool one sodium (Na) atom and one cesium (Cs) atom, bring them together, and merge them into an NaCs molecule in a specific quantum state. Such a quantum-controlled molecule is a promising building block for quantum computers and could help researchers study the quantum details of chemical reactions.

Astronomers Measure a 1-billion Tesla Magnetic Field on the Surface of a Neutron Star

Posted by in categories: cosmology, particle physics

We recently observed the strongest magnetic field ever recorded in the Universe. The record-breaking field was discovered at the surface of a neutron star called GRO J1008-57 with a magnetic field strength of approximately 1 BILLION Tesla. For comparison, the Earth’s magnetic field clocks in at about 1/20,000 of a Tesla – tens of trillions of times weaker than you’d experience on this neutron star…and that is a good thing for your general health and wellbeing.

Neutron stars are the “dead cores” of once massive stars which have ended their lives as supernova. These stars exhausted their supply of hydrogen fuel in their core and a power balance between the internal energy of the star surging outward, and the star’s own massive gravity crushing inward, is cataclysmically unbalanced – gravity wins. The star collapses in on itself. The outer layers fall onto the core crushing it into the densest object we know of in the Universe – a neutron star. Even atoms are crushed. Negatively charged electrons are forced into the atomic nuclei meeting their positive proton counterparts creating more neutrons. When the core can be crushed no further, the outer remaining material of the star rebounds back into space in a massive explosion – a supernova.

A Strange New Magnetoelectric Effect Has Been Discovered in a Symmetrical Crystal

Posted by in category: particle physics

Magnetism and electricity are linked together in many weird and wonderful ways throughout science, including the fascinating magnetoelectric effect noticeable in some crystals – where the electrical properties of a crystal can be influenced by a magnetic field, and vice versa.

Now things have gotten even weirder, because scientists have discovered a brand new magnetoelectric effect in a symmetrical crystal – and it shouldn’t be possible.

The effect was found in a specific type of crystal called a langasite, which is made up of lanthanum, gallium, silicon and oxygen, plus holmium atoms.

Physicists May Have The First Experimental Evidence of a New Type of Dark Boson

Posted by in categories: cosmology, particle physics

Two experiments hunting for a whisper of a particle that prevents whole galaxies from flying apart recently published some contradictory results. One came up empty handed, while the other gives us every reason to keep on searching.

Dark bosons are dark matter candidates based on force-carrying particles that don’t really pack much force.

Unlike the bosons we’re more familiar with, such as the photons that bind molecules and the gluons that hold atomic nuclei together, an exchange of dark bosons would barely affect their immediate surroundings.
