AI tool detects unusual satellite behavior to improve space safety

A new AI model can monitor satellites and spot anomalies in their behavior, reducing the risk of in-orbit collisions, according to new research published in the journal Expert Systems.

Ten-channel photonic interface links neutral-atom qubits in parallel

A research group in Japan has demonstrated a world-record 10-channel multiplexed quantum photonic interface based on an integrated waveguide array, a key technology for optically interconnecting multiple quantum computers. The study is published in the journal Optica.

Experiment sees surprising result in search for dark matter

For the better part of a century, people have been trying to understand dark matter. This invisible substance makes up roughly 85% of the mass in the universe but has never been directly detected. Determining exactly what it is remains one of the biggest questions about our world.

Ultrafast snapshots reveal the first moments on the way from light to electricity

Physicists at the University of Graz (Austria), in collaboration with colleagues from Marburg University and Forschungszentrum Jülich (Germany), have achieved a scientific breakthrough. For the first time, the generation of electrical energy from light has been filmed and described theoretically.

A supermassive black hole erupted in X-rays, and its radio jets followed 300 days later

By combining roughly two decades of observations from NASA’s Swift X-ray Telescope with radio monitoring, astronomers have caught a supermassive black hole at the heart of the Perseus Cluster suddenly flaring in X-rays, and about 300 days later, its powerful radio emission flared too. Their paper describing the connection between this black hole’s accretion disk and the jets it launches was submitted to the arXiv preprint server on Aug. 13 and accepted for publication in the Astrophysical Journal Letters.

Declining star formation not caused by simple ‘fuel crisis,’ new measurements suggest

The universe has been having fewer and fewer stellar “babies.” Over the past 4.5 billion years, the rate of star birth has crashed to less than half of what it once was. But here’s the twist: the most essential “fuel” for making stars has barely decreased.

Faint far-infrared radiation drives a correlated insulator-to-metal transition in magic-angle graphene

One of the central ideas in modern physics is the phase transition—a sudden transformation of the state of a material. We encounter phase transitions throughout everyday life: water freezes into ice, wax melts in the warmth of a flame, and water vapor condenses into droplets on a cold window. In these familiar examples, the atoms themselves rearrange into a new structure, giving the material entirely different properties.

ESA JUICE probe targets dark Jovian moon Kallichore in 2031

Jupiter hosts more than 100 moons, with most attention focused on the four Galilean moons: Io, Europa, Ganymede and Callisto. This is primarily due to their active geology, including Io being the most volcanically active planetary body in the solar system and Europa having a vast subsurface liquid-water ocean beneath its icy crust. However, Jupiter’s smaller, lesser-known moons could provide astronomers with key insights into the history of the solar system because they have remained largely unchanged, unlike the Galilean moons.

Looking for Earth 2.0 in binary systems

While astronomers have found thousands of exoplanets over the last few decades, the true prize continues to elude them—they have yet to find an Earth-mass, rocky planet orbiting in the habitable zone of a sun-like star. That’s partially due to cosmic geography—around half of all sun-like stars near us aren’t alone. They have one or more companion stars that complicate their orbital dynamics, as well as those of any planets they might host.

Organic crystal reveals how Joule heating stabilizes resistive switching

Metal-insulator transitions (MITs), in which a material changes from a metallic state with low resistivity to an insulating state because of a change in an external parameter, such as temperature, pressure or an electric field, are a central topic in fundamental physics research.

Four ‘Little Red Dot’ pairs hint at black hole mergers in early universe

After analyzing infrared images captured by the James Webb Space Telescope (JWST), an international team of researchers has discovered multiple massive black holes from approximately 12.5–12.8 billion years ago that were actively accumulating surrounding matter and growing rapidly. Some were even on the path to merging, according to a study published Aug. 31 in the Publications of the Astronomical Society of Japan.
