Chandra resolves NGC 6540’s mysterious X-ray flare into three separate sources

Using NASA’s Chandra X-ray spacecraft, astronomers have performed deep X-ray observations of a galactic globular cluster known as NGC 6540. The new observational campaign, described June 1 on the preprint server arXiv, focused on disentangling the nature of a peculiar X-ray flare emitted by the cluster about two decades ago.

Bidirectional manipulation of gate-free quantum electronic states via semiconductor interface engineering

A recent study published in Nature Communications demonstrates precise control over electron spatial arrangement in two directions simultaneously—without any applied voltage—through interface engineering between semimetal bismuth (Bi) thin films and two-dimensional semiconductor MoS₂.

Meet REMORA: The autonomous space fleet built to tag and track asteroids

To truly understand what an asteroid is made of, we need to send a probe to it. Remote sensing from ground-based telescopes, or even orbiting observatories, can only do so much. A new white paper submitted to the U.K. Space Agency’s 2035 Space Frontiers program (available on the arXiv preprint server) pitches just such a […]

Scientist creates ‘mini‑universe’ to measure time without a clock

A University of Birmingham scientist has built a “mini-universe” that takes a step toward answering one of science’s biggest questions: “What is time?” Publishing his findings in Physical Review Research, Professor Giovanni Barontini shows how it is possible to measure the flow of time without using a clock at all. The new findings provide a […]

Nuclear clocks tick for the first time

Two independent research teams have achieved a longstanding goal in physics: building a working nuclear clock. The devices, developed by Beichen Huang and colleagues at Tsinghua University and by Luca Toscani De Col and colleagues at the Vienna Center for Quantum Science and Technology in Austria, exploit the nucleus of a thorium-229 atom to keep […]

A cornerstone of Milky Way history may need rewriting with evidence of multiple ancient mergers

Astronomers may have uncovered new details about one of the Milky Way’s most important ancient collisions. Using data from the Dark Energy Spectroscopic Instrument (DESI) and a new clustering algorithm, researchers have found evidence suggesting the famous Gaia-Sausage/Enceladus structure (GSE) has a far more complicated origin than previously thought.

Hubble captures galaxy swarm with lensed arcs from early universe

Looking somewhat like a swarm of bees returning to their hive, this NASA Hubble Space Telescope image features the galaxy cluster MACS0329-0211. Galaxy clusters like MACS0329-0211 are important signposts in the story of how the structure of the universe evolved, and are the ultimate telescopic lenses, placing gravitationally lensed galaxies from the earliest stages of […]
