Prime focus spectrograph on the Subaru Telescope to begin science operations in February

Researchers have finished equipping the Subaru Telescope with a new special “compound eye,” culminating several years of effort. This new eye is an instrument featuring approximately 2,400 prisms scattered across the extremely wide field of view available at the Subaru Telescope’s primary focus, allowing for simultaneous spectroscopic observation of thousands of celestial objects.

Hubble rings in the new year with image of constellation Hydra

This NASA/ESA Hubble Space Telescope image reveals a tiny patch of sky in the constellation Hydra. The stars and galaxies depicted here span a mind-bending range of distances. The objects in this image that are nearest to us are stars within our own Milky Way galaxy.

NASA instrument on Firefly’s Blue Ghost Lander to study lunar interior

As part of its Artemis campaign, NASA is developing a series of increasingly complex lunar deliveries and missions to ultimately build a sustained human presence at the moon for decades to come. Through the agency’s CLPS (Commercial Lunar Payload Services) initiative, commercial provider Firefly’s Blue Ghost lander will head to the moon’s Mare Crisium for […]

World’s darkest and clearest skies at risk from industrial megaproject

On December 24th, AES Andes, a subsidiary of the US power company AES Corporation, submitted a project for a massive industrial complex for environmental impact assessment. This complex threatens the pristine skies above ESO’s Paranal Observatory in Chile’s Atacama Desert, the darkest and clearest of any astronomical observatory in the world.

Valence electrons’ role in magnetism of molecular crystals explored

Molecular crystals with conductivity and magnetism, due to their low impurity concentrations, provide valuable insights into valence electrons. They have helped link charge ordering to superconductivity and to explore quantum spin liquids, where electron spins remain disordered even at extremely low temperatures.

Physicist introduces percolation model to explain word puzzle solving behavior

Alexander Hartmann, a physicist at the University of Oldenburg, in Germany, has introduced a new model to explain a common word puzzle phenomenon. In his paper published in the journal Physical Review E, he suggests that instances where a puzzle solver experiences a sudden insight that allows them to begin finding solutions that seemed hidden […]

Resistance measurement approach successfully observes topological signatures in multiterminal Josephson junctions

Multiterminal Josephson junctions, nanoscale devices with unique electronic properties, comprise non-superconducting metallic material coupled to three or more superconducting leads. These devices have proved to be promising platforms for the exploration of topological phenomena in condensed matter physics.

Secret tunnel leading to the Great Pyramid of Giza discovered

Countless archaeological missions tried finding the road that leads to the Great Pyramid of Giza but all searches ended in failure, until a local resident living near the Giza Plateau, made one of the most important discoveries in the last decade.

During an illegal excavation beneath his home he discovered a tunnel leading to […]

Energetic particles could help to control plasma flares at the edge of a tokamak

The development of sustainable energy sources that can satisfy the world energy demand is one of the most challenging scientific problems. Nuclear fusion, the energy source of stars, is a clean and virtually unlimited energy source that appears as a promising candidate.

Space Launch System could launch a Titan balloon mission

Few places in the solar system are better suited to a balloon than Titan. The combination of low gravity and high atmospheric density makes Saturn’s largest moon ideal for a lighter than “air” vehicle, and the idea to put one there has been around for at least two decades.

AI categorizes 700 million aurora images for better geomagnetic storm forecasting

The aurora borealis, or northern lights, is known for a stunning spectacle of light in the night sky, but this near-Earth manifestation, which is caused by explosive activity on the sun and carried by the solar wind, can also interrupt vital communications and security infrastructure on Earth. Using artificial intelligence, researchers at the University of […]

Astronomers discovered 44 ancient stars using gravitational lensing—an astrophysicist explains how they did it

A group of astronomers have made history by capturing an image of a record number of stars from a time when the universe was half its age.
