New gallery of galaxies from NASA’s Chandra X-ray Observatory released

Galaxies are like cosmic gems, each with characteristics including size and shape that make them distinct. A new gallery released today from NASA’s Chandra X-ray Observatory and other telescopes displays a collection of galactic images that showcase this variety.

Exact calculations sharpen view of atomic nuclei

Every high-energy nuclear collision leaves behind a trail of clues about the structure of atomic nuclei. Deciphering those clues, however, depends on the accuracy of the underlying theory. Physicists at Osaka Metropolitan University have now performed a full calculation within Glauber theory, a cornerstone framework for describing high-energy nuclear collisions.

Chemical physicists quantitatively model electron interactions in real quantum materials

A team of scientists from Caltech and Yale University has shown for the first time how to accurately quantify an important quantum phenomenon in metals, called the Kondo effect, for specific real materials. Unlike previous approaches, which for decades have relied on simplified models to qualitatively describe the effect, the new work uses the actual atomic and electronic structures of materials to solve the problem directly.

‘Now boarding’ … 240,000 miles from Earth, at the moon’s first airport

The moon’s getting its first airport, and it’s about to get busy. Within the next two decades, NASA’s planned Gateway—humanity’s first lunar spaceport—may become a bustling hub for Orion crew capsules, lunar landers, cargo vehicles and astronauts traveling between Earth, the moon and, eventually, destinations in the deep unknown.

Setting limits on phase transitions in the dark energy era

The universe is known to be expanding at an accelerating rate. Physicists typically attribute this acceleration to dark energy, a mysterious component of the universe that exerts negative pressure, causing space to expand faster. Dark energy is thought to have become the predominant influence on the universe’s evolution around 3–4 billion years ago, at the beginning of what is known as the dark energy era.

Bright ideas accelerate the hunt for quantum emitters

The search for materials that can power future quantum technologies is accelerating, but identifying the most promising candidates remains painfully slow. Evaluating whether a material can efficiently emit quantum light requires computationally intensive simulations, making it difficult to screen the vast number of available materials.

NASA starshade would enable astronomers to directly image rocky exoworlds

A NASA-led team hopes to take a shortcut to direct imaging of extrasolar Earth-like planets. The idea is to use what they call a hybrid telescope composed of an orbital starshade coupled with the next-generation extremely large ground-based optical telescopes.

Meteorite dust holds records of magnetism that may have helped form the sun

Around 4.6 billion years ago, the solar system was little more than a giant ball of gas and dust. Over the next few million years, this “solar nebula” underwent a huge transformation, flattening into a disk of matter that then condensed to form the central sun and orbiting planets.

How the sun’s galactic journey and superflare-filled youth shaped Earth’s climate

At the center of our solar system, the sun influences every planet that orbits it. In two recent studies, scientists uncovered how ancient events in the sun’s history may have helped create Earth’s unique climate and driven previously unexplained climatic shifts.

How fusion reactions can survive flaws—up to a point

Researchers at Lawrence Livermore National Laboratory (LLNL) have found that implosions designed for inertial fusion energy (IFE) can tolerate significant imperfections before performance abruptly declines, a finding that could inform the design of fuel targets for future fusion power plants.
