A researcher, Heikki Mäntysaari from the University of Jyväskylä (Finland), has been part of an international research group that has made significant advances in modeling heavy ion collisions. New computer models provide additional information about the matter in the early universe and improve our understanding of the extremely hot and dense nuclear matter. The work is published in the journal Physical Review Letters.

A new class of highly efficient and scalable quantum low-density parity-check error correction codes, capable of performance approaching the theoretical hashing bound, has been developed by scientists at the Institute of Science, Tokyo, Japan. These novel error correction codes can handle quantum codes with hundreds of thousands of qubits, potentially enabling large-scale fault-tolerant quantum computing, with applications in diverse fields, including quantum chemistry and optimization problems.

Members of the STAR collaboration, a group of physicists collecting and analyzing data from particle collisions at the Relativistic Heavy Ion Collider (RHIC), have published a new high-precision analysis of data on the number of protons produced in gold-ion smashups over a range of energies.

Young asteroids—which formed much later than those that were created during the formation of our solar system—are typically created when larger asteroids, planetesimals, or comets collide and break up into smaller pieces. These smaller pieces form “asteroid families” that share certain properties, like their semimajor axis, eccentricity, and inclination—all of which describe their orbital paths.

The NASA/ESA/CSA James Webb Space Telescope has provided the first direct measurements of the chemical and physical properties of a potential moon-forming disk encircling a large exoplanet. The carbon-rich disk surrounding the world called CT Cha B, which is located 625 light years away from Earth, is a possible construction yard for moons, although no moons are detected in the Webb data.

This NASA/ESA Hubble Space Telescope image features a galaxy that’s hard to categorize. The galaxy in question is NGC 2775, which lies 67 million light-years away in the constellation Cancer (the Crab). NGC 2775 sports a smooth, featureless center that is devoid of gas, resembling an elliptical galaxy. It also has a dusty ring with patchy star clusters, like a spiral galaxy. Which is it: spiral or elliptical—or neither?

Growing evidence suggests that a subsurface ocean lurks beneath the icy surface of Uranus’ moon Ariel, but new research, published in Icarus, characterizes the possible evolution of this ocean, and found that it may have once been over 100 miles (170 kilometers) deep. For perspective, the Pacific Ocean averages 2.5 miles (4 kilometers) deep.

Determining the nature of dark matter, the invisible substance that makes up most of the mass in our universe, is one of the greatest puzzles in physics. New results from the world’s most sensitive dark matter detector, LUX-ZEPLIN (LZ), have narrowed down the possibilities for one of the leading dark matter candidates: weakly interacting massive particles (WIMPs).

The asteroid belt is found orbiting between Mars and Jupiter and is a vast collection of rocks that is thought to be a planet that never formed. When our solar system formed 4.6 billion years ago, the material in this region should have coalesced into a planet; however, Jupiter’s gravitational influence prevented this from happening, stirring up the region so that collisions became destructive rather than constructive. What remains today contains only about 3% of the moon’s mass scattered across millions of kilometers.

The SOAR Telescope, located on Cerro Pachón in Chile, has received a major upgrade with the installation of the SOAR Telescope Echelle Spectrograph (STELES). The long-awaited instrument achieved first light in August with observations of the binary star system Eta Carinae, along with 13 other targets. SOAR is part of U.S. National Science Foundation Cerro Tololo Inter-American Observatory (CTIO), a Program of NSF NOIRLab.

Scientists trying to work out whether a star exploded and the resulting debris crashed into Earth 10 million years ago may be one step closer to solving the mystery. They discovered an unusual amount of Beryllium-10 (10Be) at the bottom of the Pacific Ocean, which may be explained by a supernova, an exploding star.
