Astronomers discover the earliest known flickering quasar

A supermassive black hole lies at the heart of every galaxy, including the Milky Way. When a black hole is active, it pulls material in as a whirlpool of high-temperature gas and dust. As this cosmic material piles up and falls onto a black hole, it lights up its vicinity, radiating a huge amount of energy.

How Artemis II livestreamed hi-def videos and images from the moon to Earth

This April, humanity had front-row seats to space as the Artemis II Orion spacecraft transmitted crystal-clear footage of its historic journey around the moon from more than 250,000 miles (about 402,000 kilometers) back to Earth at speeds on par with home internet connections.

Nickelate superconductors share a common electronic fingerprint

Superconductors, materials that conduct electricity with zero electrical resistance at specific temperature ranges, have proved very promising for the development of quantum computers and other cutting-edge technologies. While most of these materials become superconducting at very low temperatures, others exhibit superconductivity at higher temperatures.

Mysterious signals keep coming from space: Astronomers find their ‘Rosetta stone’

A pair of stars spiraling around each other. That’s the origin of a new source of repeating radio bursts we’ve detected, called ASKAP J1745.

Could the Milky Way’s missing mass be hiding in a swarm of interstellar comets?

3I/ATLAS has caused quite a stir over the last year, inviting astronomers to update what they know about other solar systems as well as our own. However, this third interstellar visitor may have an unexpected impact on our understanding of dark matter. A new paper, available on the arXiv preprint server from researchers at the University of Hamburg, attempts to calculate the impact that the presence of large amounts of interstellar objects, or ISOs, would have on our calculation of dark matter in our galaxy.

Lunar orbiter concept could reveal five key elements across moon in two years

Researchers from Tokyo Metropolitan University have used simulations to show that a newly developed, compact X-ray telescope could be used to map the chemical composition of the entire lunar surface, a vital breakthrough for understanding its geological evolution. Detailed modeling of the detector and a realistic satellite mission show that two years would be enough to map five key elements, while an array of 5-by-5 detectors could improve resolution and get results faster.

A faster way to forecast alien weather

The TRAPPIST-1 system, located about 41 light years from Earth, has been a focal point of much exoplanetary discussion—mainly because it has seven confirmed planets orbiting a dim M-dwarf star. Two of those planets—TRAPPIST-1e and -1f—are thought to be in the star’s habitable zone. However, the habitable zone of M-dwarfs is so close to the star itself, the planets are likely tidally locked to it, meaning they have a permanent day and night side, with a “twilight terminator” in between.

Quantum circuits help AI overcome memory limitations with minimal new parameters

For millions of people, chatbots powered by large language models (LLMs) are now a key feature of everyday life. These AI systems are growing at a rapid pace, but scaling them up is becoming increasingly costly and resource-intensive.

Predictive surrogates could cut quantum computing measurement overhead by more than 99.97%

Quantum computers, systems that process information leveraging quantum mechanical effects, have the potential of outperforming classical computers on some tasks. Despite their potential, the use of these systems remains very limited, due to their high cost and other challenges that have so far prevented their large-scale fabrication.

Smart surfaces face zero gravity test in boiling heat experiments

A research team led by Davoud Jafari at the University of Twente, in collaboration with the University of Pisa, has completed a series of parabolic flight experiments to investigate advanced smart surfaces under rapidly changing gravity conditions. Conducted aboard the Air Zero G aircraft operated by Novespace, the campaign integrated additive manufacturing, boiling heat transfer and electric field control into a single experimental platform as part of the #SmartSkin project.

MUSE maps spiral galaxy W2246f, uncovering old core and ongoing star formation across disk

Astronomers have employed the Multi-Unit Spectroscopic Explorer (MUSE) on the Very Large Telescope (VLT) to perform deep spectroscopic observations of a peculiar spiral galaxy known as W2246f. Results of the observational campaign, published May 27 on the pre-print server arXiv, offer new insights into how this galaxy evolved and shed more light on its nature.
