Mercury’s crust points to deeper, hotter volcanic origins than expected

The evolutionary histories of Earth and Mercury differ fundamentally. The smallest planet, closest to the sun, likely began cooling early on, much like a setting pudding: As early as about 1 billion years after its formation, Mercury’s volcanic activity came to a halt, and a solid, continuous “rock skin” formed on the planet’s surface. Earth’s […]

Diamond clock combines two signals to cut temperature-driven drift

Despite all the advertisements for engagement rings and necklace gifts, natural diamonds are imperfect. Their carbon atoms are arranged in a cubic lattice, but they nonetheless contain several types of crystallographic defects due to impurities that occasionally replace a carbon atom. The most common types of impurities are nitrogen and boron; “Type I” diamonds contain […]

NASA telescope honors Nancy Grace Roman, architect of space-based astronomy

The Nancy Grace Roman Space Telescope is set to launch this weekend aboard a SpaceX rocket from Kennedy Space Center in Florida. When it becomes operational early next year, it will transform our view of the universe.

Light reveals internal motion in electron crystals and can trigger their melting

Electrons, particles that carry a negative electric charge, typically move through materials. At low densities and temperatures, however, the electrical repulsion between them can overpower their tendency to move, prompting them to arrange themselves into ordered patterns known as Wigner crystals.

Will new telescope Roman help reveal long-kept secrets of the universe? Q&A with an expert

On Sunday, Aug. 30, the Nancy Grace Roman Space Telescope is expected to launch from NASA’s Kennedy Space Center in Florida. The observatory will join the Hubble Space Telescope, launched in 1990, and the James Webb Space Telescope, launched in 2021, in scanning the vastness of space and potentially finding answers to longstanding mysteries of […]

Discovery reveals rapid pathways to complex aromatic molecules in space

A team of researchers led by the University of Hawaiʻi at Mānoa Department of Chemistry has uncovered a faster way large carbon-based molecules may form in space, helping solve a long-standing mystery about how some of the building blocks of the universe grow.

ASTRID traces 13.5 billion years of black hole and galaxy evolution

In dark skies at night, distant starlight twinkles and speaks to vast cosmic histories almost as old as time itself. New data from instruments such as NASA’s James Webb Space Telescope are helping astrophysicists probe deep cosmic mysteries, including the evolution of black holes and galaxies.

Milky Way’s own gravity can mimic dark matter clues, stellar stream simulations suggest

Most of the stars in our Milky Way galaxy sit neatly on a flat plane. But the space around our galaxy is much more chaotic. Rogue bands of stars called “stellar streams” orbit the Milky Way much like planets in our solar system orbit the sun.

Fast but error-prone AI assists in solving a decades-old fluid mechanics problem in five weeks

An AI assistant helped University of Colorado Boulder researchers solve a mathematical problem that had challenged their lab for a year and a half, though it made subtle errors along the way. The breakthrough could improve how scientists study nanoparticles—tiny particles about 1,000 times thinner than a human hair—but it reveals both the promise and […]
