Gravitational waves are tiny ripples in spacetime. Their first direct detection in 2015 marked a revolutionary moment in astronomy. Today, we have a thorough understanding of signals that travel far from their sources through quiet, nearly empty space, such as those emitted when black holes merge. In this case, the wave can be considered a minor disturbance on a silent background. The distinction between "background" and "wave" is clear, and the quantity measured by the detector—a tiny stretching and squeezing—is clearly determined.

A team led by York University researchers has discovered the fastest wind near a supermassive black hole ever found at ultraviolet wavelengths, driven by the disk of matter (quasar) surrounding the black hole.

JWST found a black hole hiding in a galaxy more than 10 billion light-years away from Earth, and used a cosmic magnifying glass to determine its mass.

The most distant, nearly invisible dormant black hole has been detected and "weighed" by an international team of astronomers that includes researchers from UCL. The study, published in Science, identified a dormant black hole at the heart of a galaxy known as MRG-M0138 located over 10 billion light years away. It is the most distant dormant black hole yet detected, 15 times farther away than the previous record.

The Majorana 2 quantum processor is built from topological qubits, and its creators claim it can sustain quantum coherence for an average of 20 seconds — orders of magnitude longer than the milliseconds that conventional chips last.

DNA is the blueprint of the human body. However, tens of thousands of DNA lesions occur in our bodies every day. In particular, if "apurinic/apyrimidinic sites" (AP sites, damaged sites where one letter of DNA information has been erased) are not properly repaired, they can lead to cancer and aging.

Electrons around Jupiter have been caught in the process of being accelerated, revealing a potentially unified mechanism for particle acceleration. The findings, published in Nature, may help constrain how energetic particles are produced throughout the universe.

Scientists at the U.S. Department of Energy's (DOE) Argonne National Laboratory are helping show what it means to design a material almost atom-by-atom.

Nanodiamonds are tiny diamond particles only a few nanometers in size. Because they are chemically highly stable and can host so-called color centers, optically active defects in the crystal lattice, they are considered promising materials for quantum technologies, sensing and biomedical research. Until now, however, it has been difficult to reliably produce nanodiamonds with uniform size, high purity and precisely integrated optical properties.

Quantum computing, once only a theoretical possibility, promises to deliver faster, more energy-efficient computers—but only if scientists can build and scale the hardware needed to run the machines. New research from Virginia Commonwealth University brings scientists one small step closer to quantum computing at a practical scale, which could help dramatically reduce energy usage and computing times in some industries.

Why do certain surfaces behave very differently from what theoretical calculations suggest? Scientists long assumed that the aluminum oxide surface should be highly reactive and capable of splitting water molecules. In experiments, however, this behavior is barely observed.

Everyone knows that finding the right sauce recipe can make or break a barbecue, but now astronomers are using BBQSORS (pronounced "barbecue sauce") as part of the recipe to explain quasars, some of the brightest objects in the universe. These results were made possible by data from a new instrument on the Subaru Telescope.

Ultrafast lasers emit pulses lasting only a few hundred femtoseconds (quadrillionths of a second). These flashes of light power applications from precision micromachining to eye surgery to optical frequency combs, the Nobel Prize-winning technology behind today's most precise optical atomic clocks. Yet despite more than two decades of effort, ultrafast lasers have largely remained bulky, expensive systems confined to optical tables.

Galactic collisions are events of breathtaking proportions. The supermassive black holes (SMBHs) at their centers plunge into a chaotic orbital dance that eventually coalesce into a single remnant. On their way to that point, they could eventually get "kicked" out of the center of their galaxy—and finding these "recoiling" black holes has been a challenge of cosmology for decades. A new paper, made available on the arXiv preprint server by an international team, used a novel idea to track down these fast-moving behemoths.

Black holes, regions in space where gravity is so strong that nothing can escape, have been widely studied over the past decades, due to their unique and intriguing properties. Einstein's theory of general relativity predicts that black holes obey a set of rules, known as the laws of black hole mechanics. These rules somewhat resemble the laws of thermodynamics, which delineate how energy, heat, and entropy behave in our universe.

Ever since the JWST revealed a population of SMBH in the early universe that were overmassive, scientists have been working hard to explain them. These black holes existed when the universe was only about 2 billion years old, during Cosmic Noon, and according to our models of black hole growth, there simply wasn't enough time for them to grow so massive.

The physics of neutron stars are almost too fantastic to believe: something the weight of two suns compacted to a sphere the size of a city. Each teaspoon of its material would weigh billions of tons. If you've done any reading on the topic, you've heard these facts before. But despite the intense interest these extreme objects hold, we are still actively learning lots about them.

When rockets fire into space, the insides of their engines become an extreme environment where temperatures soar and tiny particles are thrown around at hypersonic speeds. These particles behave in ways that break long-held assumptions, according to new research that could help improve the durability, safety and performance of future space and defense technologies.

Researchers have discovered that atoms can be mixed, separated, and recombined within the same experiment, providing a pathway to a record-breaking catalyst for green hydrogen production. In their study, the team created nanoscale particles containing only a few dozen platinum and nickel atoms and observed unusual dynamic behavior in direct space and in real time. As the two metals separate from one another while maintaining an interface, they become highly active for electrochemical water splitting, leading to efficient hydrogen evolution.

Microsoft’s announcement of a new quantum computing breakthrough with its Majorana 2 chip continues a trend of bold claims followed by scant evidence

Swapping materials in its Majorana 2 chip boosted the effectiveness of quantum bits that rely on the math of topology to reduce errors, Microsoft says.

One must act fast to truly understand the fundamental properties of a molecule or material, including how it interacts with light or electromagnetic forces. Accordingly, ultrafast lasers that generate femtosecond-duration coherent light pulses have provided researchers with a powerful tool for probing molecular and even atomic-scale phenomena.

By definition, elementary particles can't be broken into smaller pieces. But in a new theoretical study published in Physical Review Letters, Johannes Skaar and colleagues have revealed what would happen if you tried anyway for a single photon. The answer is deeply strange: attempting to cut a photon in two wouldn't produce two smaller photons, but instead conjure an infinite number of them out of thin air.

Astronomers monitoring a nearby active galaxy for six years have watched its supermassive black hole dramatically wake up, brightening by a factor of 10 across ultraviolet and X-ray wavelengths. The paper outlining the study was posted to the preprint server arXiv on May 18.

Scientists have created a tiny chip that can generate, steer, and read light-based information all in one device, marking a major leap toward ultra-fast, energy-efficient computing. The breakthrough uses atomically thin materials and nanoscale structures to control a unique quantum property of light called the “valley” degree of freedom, allowing information to be encoded in new ways.

The JWST found an abundance of overmassive black holes at high redshifts, pushing the limits of black hole (BH) science in the early Universe. Results have claimed that these BHs are significantly more massive than expected from the BH mass-host galaxy stellar mass relation derived from the local Universe. But new research shows they were just outliers in the normal range of masses that don't require any special causes.

Quantum entanglement is a state in which particles are entwined with each other. In this entwined state, the properties of one particle influence the other, even when they aren't physically close to each other. This phenomenon has often been observed in small quantum systems with only a few particles in them, where researchers can use it to store and process quantum information. Rice University professor Qimiao Si is interested in understanding and applying quantum entanglement to macroscopic systems with vast numbers of particles.

It’s 2165, and methane is in high demand, especially after the Titan Treaty of 2145 made it illegal to harvest methane from Saturn’s moon, Titan. But the advent of interstellar travel has made exoplanetary exploration far easier, enabling corporations to identify and harvest methane from exoplanets. However, it’s far cheaper and easier to harvest methane from exoplanets with reasonable (also called temperate) temperatures, because it means higher quantities of methane. The Exoplanet Exploration Corporation decides to send its first ship to one such exoplanet loaded with methane that could bring their quarterly financial statements back into the green.

For nearly thirty years, dark energy has been cosmology's great get out of jail free card, the invisible, mysterious force we invented to explain why the universe is expanding faster than it should be.

Every galaxy we know of spins. It's one of those rules of the universe so fundamental that astronomers barely think about it anymore. So when the James Webb Space Telescope pointed at one of the most massive galaxies in the early universe and found…well nothing. No spin, just stillness. They had to look twice.

Supermassive black holes are the largest known black holes in the universe, sitting at the center of most large galaxies. They are sometimes described as cosmic monsters because they feed on surrounding gas and dust when they are active, as well as destroy anything that gets too close. But their reputation could be due for a rethink, as a new paper published on the arXiv preprint server suggests they may also be the birthplace of millions of planets.

Researchers have developed a compact quantum detector that makes terahertz radiation much easier to detect. A specially designed metasurface funnels incoming energy into tiny active regions, greatly strengthening the electrical signal produced.

From satellite imagery to clandestine price reports, a new study draws on North Korea to explore economic activity in opaque regimes and information-scarce regions. North Korea is the blackest of economic black holes. Even a basic question like "is the economy shrinking or expanding?" can be difficult to answer. The country does not publish reliable statistics. It sharply restricts outside access and treats trade data as a state secret.

Understanding the dynamics of how water moves is deceptively simple in concept and endlessly complex in practice. Real-world marine environments are anything but controlled: weather, seasons, and geography change constantly. Yet understanding water movement is a critical aspect in areas of study like marine biology, coastal and environmental science, and even policy around how we recover from natural disasters.

For nearly a century, there were two known kinds of magnets. Ferromagnets are the classic magnets that attract metal and keep pictures stuck to the refrigerator. Antiferromagnets hide their magnetism at the atomic scale but are increasingly prized for their technological potential.

A decades-old mystery about Saturn has finally been solved thanks to the James Webb Space Telescope. Scientists discovered that Saturn’s changing “rotation rate” was never caused by the planet speeding up or slowing down, but by powerful winds high in its atmosphere. Webb’s unprecedented observations revealed that Saturn’s northern lights actively heat the atmosphere, creating winds that generate electrical currents, which then power the aurora all over again in a self-sustaining cycle.
