Primordial black holes (PBHs) are black holes theorized to have formed shortly after the Big Bang. Compared to black holes emerging from collapsing stars, PBHs could have very different masses, ranging from very small to extremely large.

An international team of astronomers reports the discovery of a new dusty star-forming galaxy at high redshift. The newfound galaxy, designated AC-2168, was detected using the Atacama Large Millimeter/submillimeter Array (ALMA) and the Northern Extended Millimeter Array (NOEMA). The finding was detailed in a paper published Nov. 11 on the pre-print server arXiv.
A geomagnetic superstorm is an extreme space weather event that occurs when the sun releases massive amounts of energy and charged particles toward Earth. These storms are rare, occurring about once every 20–25 years. On May 10–11, 2024, the strongest superstorm in over 20 years, known as the Gannon storm or Mother’s Day storm, struck Earth.
While atmospheric turbulence is a familiar culprit of rough flights, the chaotic movement of turbulent flows remains an unsolved problem in physics. To gain insight into the system, a team of researchers used explainable AI to pinpoint the most important regions in a turbulent flow, according to a Nature Communications study led by the University of Michigan and the Universitat Politècnica de València.
Quantum computers, which operate leveraging effects rooted in quantum mechanics, have the potential of tackling some computational and optimization tasks that cannot be solved by classical computers. Instead of bits (i.e., binary digits), which are the basic units of information in classical computers, quantum computers rely on so-called qubits.
The once standing stone of Er-Grah is one of the unsung wonders of the ancient world. It was the biggest megalith ever erected in history and was raised in France (Brittany) during the Neolithic, 4700 BCE. It is believed to have stood for 700 years before breaking into four pieces at around 4000 BCE. The impressive dimensions of this menhir still divide specialists about the techniques used for transport and erection. This great megalith weighed 280 tonnes, which even the machines of today would find challenging to move and erect. The fact that this was achieved during the Neolithic makes it one of the most remarkable engineering feats of the ancient world.
Etched into the surface of this great monument is a sculpture representing a hatchet-plow. It was quite common to find these petroglyphs (primitive symbols) marked onto the surface of ancient megaliths. Sadly, the original meaning of these symbols has been lost to the annals of time. In my upcoming short stories, I’ll offer you an insight into what these megaliths were really used for. This was a world where standing stones created a sacred network, connecting the hearts and minds of our ancestors. The Great Menhir of Er-Grah was one of the most powerful of these artifacts, and I hope to reveal its secrets in the near future. Article by Simon E. Davies, contributor to Ancient Code. NASA unveiled close-up pictures on Wednesday of the interstellar comet that’s making a quick one-and-done tour of the solar system.
The nature of time has plagued thinkers for as long as we’ve tried to understand the world we live in. Intuitively, we know what time is, but try to explain it, and we end up tying our minds in knots.
NASA’s James Webb Space Telescope has delivered a first of its kind: a crisp mid-infrared image of a system of four serpentine spirals of dust, one expanding beyond the next in precisely the same pattern. (The fourth is almost transparent, at the edges of Webb’s image.)
Imagine the catastrophic winds of a category 5 hurricane. Now, imagine even faster winds of more than 100 meters per second, encircling the planet and whipping clouds across the sky, with no end in sight. This scenario would be astonishing on Earth, but it’s business as usual on Venus, where the atmosphere at cloud level rotates about 60 times faster than the planet itself—a phenomenon known as superrotation. In contrast, Earth’s cloud-level atmosphere rotates at about the same speed as the planet’s surface.
Researchers from HSE University and the Space Research Institute of the Russian Academy of Sciences analyzed seven years of data from the ERG (Arase) satellite and, for the first time, provided a detailed description of a new type of radio emission from near-Earth space—the hectometric continuum, first discovered in 2017.
What makes art art? Is it the method or the creator? Does it need a color palette and oil paints, or a canvas laid flat on the floor and paint splattered across it? Does it require a critically acclaimed painter, or a toddler with crayons? And when it comes to the artist, can we even reliably tell if an artwork has been created by children or adults?
Using lasers as tweezers to understand cloud electrification might sound like science fiction, but at the Institute of Science and Technology Austria (ISTA) it is a reality. By trapping and charging micron-sized particles with lasers, researchers can now observe their charging and discharging dynamics over time.
In 1887, one of the most important experiments in the history of physics took place. American scientists Michelson and Morley failed to measure the speed of Earth by comparing the speed of light in the direction of Earth’s motion with that perpendicular to it. That arguably most important zero measurement in the history of science led Einstein to postulate that the speed of light is constant and consequently to formulate his theory of special relativity.
Physics is often about recognizing patterns, sometimes repeated across vastly different scales. For instance, moons orbit planets in the same way planets orbit stars, which in turn orbit the center of a galaxy.
