What do you see when you look up at the night sky? While everyone may have a different answer, the truth is that almost everything out there is hydrogen. The first element in the periodic table is by far the most abundant substance in the cosmos. It's the fuel of stars and the raw material from which the heavier elements were forged over billions of years. Even the sun is, at its core, a furnace for fusing hydrogen atoms together.

The Earth is surrounded by an invisible barrier that was thought to prevent highly energetic electrons from reaching closer to our planet. But in 2024, Japan's Arase space probe detected these electrons well inside the barrier. Now, research led by Nagoya University has found evidence that the electrons were accelerated locally rather than infiltrating from outer radiation belts.

More than a century after Einstein first devised the equations that describe gravity, physicists are still finding new ways of interpreting them. Luca Comisso, an associate research scientist in Columbia University's departments of Astronomy and Physics and the Columbia Astrophysics Laboratory, and Felipe A. Asenjo of Universidad Adolfo Ibáñez in Chile, recently found a new way of looking at Einstein's equations that reveals a striking analogy with "magnetic reconnection" in plasmas, which occurs when magnetic field lines break and reconnect, powering explosive phenomena such as solar flares.

Researchers at Delft University of Technology (the Netherlands) have succeeded in controlling the magnetism in the nucleus of a single atom with radio waves. This came as a surprise: until now, physicists believed that this nuclear spin could not be manipulated directly. The discovery could open up new possibilities for storing and reading quantum information. The research is published in the journal Nature Communications.

When two objects touch and then separate, they can swap tiny amounts of electric charge, even if they are made from exactly the same material. This 'triboelectric effect' is the source of everyday static electricity, but it is still poorly understood in large samples of powder, where vast numbers of particles are constantly colliding with each other.

Researchers at the Linac Coherent Light Source (LCLS) at the U.S. Department of Energy’s SLAC National Accelerator Laboratory have measured the shortest high-energy x-ray pulses ever recorded at an x-ray free-electron laser (XFEL). The pulses had photon energies of about 9 keV and clocked in at durations of 100 as to 400 as. These high-energy, or “hard” attosecond x-ray pulses are invaluable to researchers studying the universe at its smallest, fastest scales. “The pulses are both energetic enough to look deep into atomic systems and fast enough to record electronic motion frozen in time,” said Agostino Marinelli, a professor of photon science, particle physics, and astrophysics at SLAC.

Neutrinos are among the most abundant particles in the universe, but they are also among the most elusive. Nearly massless, they are produced by nuclear reactions in the sun, exploding stars, particle accelerators and even the decay of radioactive elements on Earth. They interact so weakly with ordinary matter that trillions pass through each person every second without leaving a trace. Studying these ghostly particles could help answer some of the biggest questions in physics, from the nature of dark matter to why matter exists at all.

Dense stellar environments were common in the early Universe. These environments fostered more numerous stellar collisions, and some of those would've been mergers that formed very massive stars. Those stars would've exploded as supernovae, becoming massive black holes, the potential seeds for today's supermassive black holes.

Researchers from Jülich, Aachen and Cologne have performed a quantum operation on a qubit in just 6.8 nanoseconds—with more than 99.98% accuracy. Such operations typically take several tens of nanoseconds in superconducting quantum computers. The paper was published in Nature Communications.

Designing structural high-entropy alloys (SHEAs) means solving a problem with an enormous number of moving parts: which combinations of composition and processing conditions will yield the phases, microstructures, and mechanical properties a given application demands? Because these alloys mix multiple principal elements in comparable proportions, that question spans length and time scales that no single experiment or model can cover on its own.

DNA-nano/microparticle motors are among the fastest artificial molecular motors reported to date, moving at approximately 30 nm per second. However, they are still slower than natural motor proteins (approximately 100–1,000 nm per second), and further improvements in design and performance are required.

A hypothetical particle could have briefly held more energy than everything else in the infant universe combined, which could help explain how matter won out over antimatter.

To produce hydrogen using sunlight, the energy obtained from light must be retained until it can be used in a chemical reaction. However, if an electron that has gained energy from light quickly returns to its original position, it becomes difficult to make use of that energy.

Quantum computers need qubits that can be controlled both quickly and reliably. Yet making semiconductor spin qubits faster often makes them more sensitive to electrical noise, creating a difficult trade-off.

A new study reveals a dust-reddened quasar from a time when the universe was less than a billion years old. Located at a redshift of 6.5488, the object J1440+0019 contains a rapidly accreting supermassive black hole with a mass of about 1.1 billion suns. The paper was posted to the arXiv preprint server on Oct. 9.

One of the fundamental challenges of quantum computing is obtaining information from a quantum bit, or qubit. Unlike a conventional bit, which can be read repeatedly without altering its content, direct measurement of a quantum system typically causes the state to collapse before it can be determined. In other words, reading the information modifies it.

Astronomers have discovered three actively feeding black holes inside a single galaxy more than 12.5 billion light-years away, revealing a remarkable scene from the universe’s infancy. Two of the black holes are separated by just 620 light-years and are expected to eventually merge, while a third lurks farther away. One weighs an astonishing 80 million suns, and another is growing faster than conventional theories predict.

The positron is the antimatter counterpart of the electron, identical in mass but carrying an equal and opposite electric charge. Like the electron, it also behaves like a tiny bar magnet, and according to a key prediction of the Standard Model of particle physics, its magnetic moment should be exactly equal and opposite to the electron's.

In 1953, two physicists showed that an electron beam skimming past a grating emits light whose color depends only on the electron's speed and the grating's spacing. Known as Smith-Purcell radiation, this phenomenon has become a useful tool for building compact, tunable light sources and tracking particle beams without touching them.

Two black holes can collide and merge into one. But could the opposite happen: could a single black hole split into two smaller ones? That question is explored in a new theoretical study: "When Black Holes Admit Pair-of-pants Topologies," published in the journal Physical Review D.

Quantum systems can occupy superpositions, quantum states that combine different possibilities. For instance, a microwave field can be prepared in a superposition of an empty state and a state that contains microwave light.

Researchers have solved a long-standing challenge in understanding how tiny defects in materials like diamond and silicon carbide behave when exposed to light. Their new computational method revealed a surprisingly important energy-loss mechanism in silicon carbide that scientists had previously underestimated. The finding helps explain a mystery that has puzzled researchers for years and could improve the design of quantum computers and sensors.

Typically, when we think of exoplanets, we think of neat spheres floating directly in front of their star, which acts as a giant spotlight. From our vantage point, they would look more like two perfect two dimensional circles than spheres, though. But nature is almost never so clean-cut. A new paper published in Nature Astronomy from researchers at Cornell and the University of Bristol details the first-ever study of an exoplanet that is noticeably lopsided.

This year, Francis Halzen earned the Nobel "for decisive contributions to the IceCube Neutrino Observatory and the discovery of high-energy neutrinos of astrophysical origin."

Researchers have observed a molecule in the first instants after it has absorbed light and tracked the coordinated motion of electrons and nuclei with a temporal resolution of three femtoseconds. This is the result achieved by an international research group led by the Politecnico di Milano, which has developed a new apparatus for studying ultrafast photochemical processes.

A joint research team fabricated a two-dimensional structure that exhibits properties of both the honeycomb and Kagome lattices using organic molecules. They discovered that edge states specific to topological materials (states that exist only at the edges and are distinct from those in the interior) appear in this structure.

As the climate gets warmer, the number of particles that make up clouds in the Arctic may increase or decrease, depending on the specific area. A new study indicates that the Arctic should be divided into three parts rather than considered as a whole.

SMBH jets are driven by thick, hot accretion disks with powerful magnetic fields. But there's a bit of a paradox. Some SMBH produce jets, even though they appear to have thin, cold accretion disks. New research has solved this paradox, showing that disks can be truncated into an outer cold disk and an inner hot disk.

Ever since quantum mechanics first described particles, like electrons, as rippling waves, researchers have wondered if those waves could be trapped in place. Writing today in Science a century later, a team of Columbia University researchers reports waves of electrons becoming trapped for the first time in a metal called Pd₅AlI₂.

Theory says that during some SMBH mergers, the merger remnant receives a recoil kick from gravitational waves. Instead of sitting placidly in the galactic center, these recoiled SMBH are sent on a pendulum-like motion, back and forth through the galactic center. New research has found statistical evidence supporting their existence.

The force exerted by a gas usually results from many atoms or molecules at once. But scientists isolated the force of a lone particle.

By analyzing data on around 100,000 quasars, or extremely luminous galactic nuclei, researchers at Eötvös Loránd University (ELTE) have found statistical evidence that some supermassive black holes at the centers of galaxies are ejected from their positions after forming.

Technion researchers have presented evidence for the existence of solar-storm-like outbursts near supermassive black holes, which can be a million times larger than the sun or more. The phenomenon was discovered in the vicinity of the black hole in the galaxy NGC 3783, and the researchers' findings were published in The Astrophysical Journal Letters.

Scientific estimates show that there should be between about 100 million and 1 billion stellar-mass black holes in the Milky Way. But they aren't easy to locate. They're not like supermassive black holes (SMBH) at the centers of galaxies. Those are usually easy to spot for different reasons.

Unlike classical physics, quantum mechanics generally cannot tell us exactly what will happen in an individual event. Instead, it predicts the probabilities of different outcomes. As one of the theory's early pioneers, Erwin Schrödinger played a key role in debates about what this randomness really means. However, part of his contribution has stayed hidden for more than 80 years.
