A meteor crater buried beneath Oklahoma has turned out to be nearly 100 million years younger than scientists thought. Zircon crystals show the Ames impact occurred about 370 million years ago, meaning it was not part of the mysterious Ordovician ...

Tiny magnetic fields created shortly after the Big Bang may help explain the long-running disagreement over how fast the universe is expanding. Detailed simulations show that these primordial fields could have changed the formation of hydrogen in the ...

A new light-activated material can efficiently produce hydrogen from water without requiring an additional expensive metal catalyst. Researchers say its unusual sulfur-based chemistry could point toward cheaper and more practical ways to turn ...

ESA's Juice spacecraft raced past Earth on September 28, using our planet's gravity to dramatically reshape its path toward Jupiter without burning much fuel. The flyby changed its direction by 20 degrees and increased its speed by 3.5 km/s, while .. ...

Scientists studying Chang'e-6 lunar soil have discovered a previously unknown magnetic mineral in natural Moon samples: a form of metallic iron called -Fe. Found inside tiny impact-glass particles, the nanoscale iron can preserve a stable magnetic .. ...

Ultra-detailed simulations are showing how the first stars lit up the dark Universe and seeded space with elements such as carbon, oxygen, and iron. The MEGATRON project could bridge JWST observations of the earliest galaxies with chemical clues ...

Researchers have demonstrated that quantum fluctuations in supposedly empty space can strengthen superconductivity, raising the transition temperature of an ultrathin material by as much as 5.4%. The discovery opens the possibility of using specially ...

NASA's Roman Space Telescope has demonstrated remarkable pointing stability and given its powerful planet-imaging coronagraph its first look at the cosmos. The telescope can already stay locked on a target with precision comparable to aiming a laser ...

JWST has revealed that galaxies were spreading carbon, oxygen, and other heavy elements through space just 500 million years after the Big Bang. The surprising discovery suggests the young universe became chemically enriched much earlier than ...

Ultrashort electrical pulses allowed scientists to push superconductors closer than ever to the point where their electron pairs actually break apart. The method revealed hidden differences between superconducting materials and could open new ways to ...
