Sixty-three light-years from Earth, in the small, faint constellation known as Pictor (which is Latin for “painter”), there lies a strange structure that has puzzled astronomers for the last two years. Nicknamed the “Cat’s Tail,” this dark feature stretches across an abyss of space about a thousand times the average distance between Earth and the sun.
Magnetic fields exist in many stars, including the sun. Yet they remain too poorly understood to be reliably included in stellar evolution models, limiting their accuracy. Now, a new study by researchers at the Institute of Science and Technology Austria (ISTA), published in Astronomy & Astrophysics, shows why a star’s “criminal” evolutionary history may be crucial for correctly interpreting its internal magnetic fields.

Theoretical physicists at Emory University have discovered a way to use light to detect the “spectral fingerprints” of anyons—exotic quasiparticles that emerge from the collective behavior of many electrons. Their findings are published in Physical Review Letters. The work offers a new tool for the study of anyons, which hold potential as fundamental building blocks for quantum computing.
Modest gamma-ray flash followed by dazzling afterglow points to powerful stellar jet viewed off-axisA cosmic explosion that announced itself with a modest flash of gamma rays went on to produce one of the brightest afterglows astronomers have recorded in the past 20 years. An international team of astronomers now finds evidence that the surprising mismatch comes down to perspective: Earth was outside the most intensely beamed light from the explosion.
Researchers at Kyushu University have found that an ultrathin layer of iridium manganese (IrMn) can improve two spin-related signals in a structure made of a magnetic insulator and a platinum film. By examining how spin currents are generated and absorbed, the team gained insights into how the intermediate layer improves spin transfer. The findings could inform the development of ultralow-power devices for computing and energy harvesting.
Planning a successful trip can be challenging, especially when your destination is in outer space. Even before liftoff, space missions require extraordinary amounts of scientific preparation and data analysis to succeed, which can take years to complete. However, as space agencies race to establish a permanent presence on the moon, using artificial intelligence to combine such information into a single system could make mission planning much more efficient.
Glasses are (mostly) brittle, metals can be ductile (plastic), and liquids flow easily. Polymers are interesting because they exhibit all three types of behavior, depending on their chemical nature, temperature, and deformation rate. If polymers are not able to crystallize, their low-temperature state is glassy, and they are hard and transparent. One example is poly(methylmethacrylate) [PMMA], which has been used as an artificial glass since the early 20th century.
Despite public protests from residents, Oxford council members voted 5-2 to dissolve the community’s 100-year-old police department
A team of researchers has produced the first global, three-dimensional estimates of the sun’s magnetic field, including the area beyond the sun’s visible edge. This marks a step toward more accurate models of solar activity—and ultimately, better predictions of solar magnetic eruptions, which are the root cause of extreme space weather that can impact critical infrastructure technologies on Earth.
Using advanced new simulations, a team of astronomers in the U.S. has developed a promising new theory for how giant, gaseous exoplanets migrate into stiflingly close orbits around their host stars. Led by J. J. Zanazzi at The Pennsylvania State University, the team showed how both massive “hot Jupiters” and smaller, Neptune-sized planets could migrate from distant, elliptical orbits as they release energy via dramatic shock waves in their outer atmospheres. Their results have been published in The Astrophysical Journal.

An NMR spectrometer can reveal molecular structure down to the atomic level, but weak signals limit what it can see. Now, Aarhus University researchers have used AI to let the spectrometer learn the best pulse sequence directly from the sample.
Finding an Earth-like world beyond the solar system is the holy grail of exoplanet research, and the field has seen remarkable technological advances in detecting and studying exoplanets since the first confirmed exoplanet around a sun-like star was discovered in 1995. These advances include ground- and space-based telescopes, notably the James Webb Space Telescope. Although astronomers have already directly imaged some exoplanets, directly imaging Earth-like planets around sun-like stars remains a major technological challenge, primarily because these planets are extremely faint compared with their host stars and appear very close to them in the sky.
