Quantum cutting, upconversion, and temperature sensing help with thermal management in silicon-based solar cells

Introducing light conversion materials into silicon-based photovoltaic devices is an effective way to improve their photoelectric conversion efficiency. Light conversion materials include quantum cutting materials and upconversion materials. …read more […]

New method spots cosmic threats by extracting 3D direction of plasma ejections from sun’s 2D ultraviolet images

A team of scientists has unveiled a novel method for the early estimation of coronal mass ejection (CME) direction in 3D space. The groundbreaking technique, named DIRECD—”Dimming InfeRred Estimate of CME Direction”—will provide crucial data to mitigate potential adverse impacts on various industries and technological systems both in space and on Earth. …read more […]

Asteroid that impacted near Berlin identified as a rare aubrite

An official classification now aligns with what many suspected from merely looking at the images of the strange meteorites that fell near Berlin on January 21, 2024. They belong to a rare group called “aubrites.” …read more […]

Research offer direct view of tantalum oxidation that impedes qubit coherence

Scientists at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory and DOE’s Pacific Northwest National Laboratory (PNNL) have used a combination of scanning transmission electron microscopy (STEM) and computational modeling to get a closer look and deeper understanding of tantalum oxide. When this amorphous oxide layer forms on the surface of tantalum—a superconductor that shows great promise for making the “qubit” building blocks of a quantum computer—it can impede the material’s ability to retain quantum information. …read more […]

Scientists create effective ‘spark plug’ for direct-drive inertial confinement fusion experiments

Scientists from the University of Rochester’s Laboratory for Laser Energetics (LLE) led experiments to demonstrate an effective “spark plug” for direct-drive methods of inertial confinement fusion (ICF). In two studies published in Nature Physics, the authors discuss their results and outline how they can be applied at bigger scales with the hopes of eventually producing fusion at a future facility. …read more […]

An astronaut controls a robotic dog from orbit

Swedish astronaut Marcus Wandt took control of a series of robots in Germany while on board the International Space Station, zipping around the Earth at 28,000 kilometers per hour (17,500 mph.) Researchers want to understand how time delays can affect the remote control of robots from an orbiting platform. Future astronauts could control rovers on the moon or Mars from a spacecraft in orbit. Until now, only wheeled rovers have been part of the tests, but now they have added a dog-like robot called Bert. …read more […]

Plan for Europe’s huge new particle collider takes shape

Europe’s CERN laboratory revealed more details Monday about its plans for a huge new particle accelerator that would dwarf the Large Hadron Collider (LHC), ramping up efforts to uncover the underlying secrets of the universe. …read more […]

Scientists use AI to investigate structure and long-term behavior of galaxies

Bayreuth scientists are investigating the structure and long-term behavior of galaxies using mathematical models based on Einstein’s theory of relativity. Their innovative approach uses a deep neural network to quickly predict the stability of galaxy models. This artificial intelligence-based method enables efficient verification or falsification of astrophysical hypotheses in seconds. …read more […]

Hubble views dim but distinct spiral galaxy UGC 11105

This image of the softly luminous spiral galaxy UGC 11105 is from the NASA/ESA Hubble Space Telescope. It lies about 110 million light-years from Earth in the constellation Hercules. …read more […]

Tiny NASA cameras to picture interaction between lander, moon’s surface

Say cheese, moon. We’re coming in for a close-up. As Intuitive Machines’ Nova-C lander descends toward the moon, four tiny NASA cameras will be trained on the lunar surface, collecting imagery of how the surface changes from interactions with the spacecraft’s engine plume. …read more […]

How dangerous are kilonovae?

When we look up at the sky on a particularly dark night, there is a sense of timelessness. We might see the flash of a meteor, and occasionally a comet is visible to the naked eye, but the cold and distant stars are unchanging. Or so it seems. There can also be a sense of calm, that despite all the uncertainty of the world, the stars will always watch over us. …read more […]
