Off-center stellar death points to wandering supermassive black hole stripped of its own galaxy

Astronomers have uncovered new details about the black hole that ripped apart a star in a tidal disruption event named AT2024tvd. Findings suggest it is a wandering supermassive black hole—the kind that is not located at the center of a visible galaxy. The paper outlining this research was published in The Astrophysical Journal Letters on […]

New millisecond pulsar discovered with the Murchison Widefield Array

Using the Murchison Widefield Array (MWA), astronomers have discovered a new millisecond pulsar as part of the ongoing Southern-sky MWA Rapid Two-metre (SMART) survey. The discovery is reported in a research paper published June 17 on the arXiv preprint server. The work has also been accepted for publication in The Astrophysical Journal Letters.

Non-Hermitian geometry reveals when quantum amplification depends only on start and end points

In quantum mechanics, the geometry of quantum states has emerged as a powerful framework for understanding phenomena ranging from electrical conductivity to superconductivity. One research direction aims to extend these geometric concepts to non-Hermitian quantum mechanics—where systems can exchange energy with their environment—including the generalization of the Berry phase, a key geometric quantity, to the […]

Man convicted of firing more than 20 gunshots at Calif. deputies in 6-hour standoff

Over six hours, the man fired his gun no less than 24 times; one gunshot struck a cruiser where deputies were taking cover, and one struck an armored vehicle where a deputy was seated

New driving model predicts split-second crash avoidance with humanlike accuracy

Scientists at Delft University of Technology, in collaboration with Waymo, have developed a new model that predicts with high accuracy how human drivers respond to dangerous traffic situations. For the first time, different types of collision avoidance behavior are combined into a single model. The results will be published on 10 June in Nature Communications. […]

Uranus, Neptune may be magma worlds, not ice giants

Uranus and Neptune remain two of the most mysterious objects in the solar system, primarily because they have been visited only by NASA’s Voyager 2 spacecraft in 1986 and 1989, respectively. Their “ice giant” moniker comes from longstanding hypotheses that their interiors are comprised of an icy mantle beneath their hydrogen-helium atmospheres. While Jupiter and […]

Clean crystal surface lets single molecules hit ultimate quantum limit

Scientists at the Max Planck Institute for the Science of Light (MPL) have developed a technique for interrogating molecules on surfaces with spectroscopic precision, thereby reaching the ultimate quantum limit for the first time. With their findings, published in Science, the researchers open new opportunities for the study of molecule-surface interactions and molecular quantum technologies. […]

Pegasus launch to deploy LINK for months‑long orbit boost of aging Swift

A mission to raise the orbit of NASA’s Neil Gehrels Swift Observatory is poised for launch no earlier than Tuesday, June 30, at 6:23 a.m. EDT (10:23 p.m. UTC+12), from Kwajalein Atoll, part of the Republic of the Marshall Islands in the South Pacific Ocean.
