Meteorites are vital tools for investigating planetary formation and evolution, yet most are lost to atmospheric and geological processes on Earth. Carbonaceous Ivuna-type (CI) chondrites are particularly rare, representing less than one percent of terrestrial meteorite finds.

A 19th-century hypothesis dismissed for decades is now illuminating one of physics' most perplexing mysteries: why our universe is made primarily of matter rather than antimatter. Researchers in Japan have proposed that knotted energy fields, or "cosmic knots", arising naturally in an expanded particle physics model, may have briefly dominated the early universe and tipped the balance in favor o

Researchers in China have unveiled a previously unknown pattern in solar radio emissions, observed during a major flare on May 8, 2024. The discovery comes from observations made using the Chashan Broadband Solar Radio Spectrometer (CBSm), which records solar signals between 90 and 600 MHz. Scientists identified a series of bright, narrow bands drifting slowly down in frequency, each less than 1

For centuries, humans have sought to study the stars and celestial bodies, whether through observations made by naked eye or by telescopes on the ground and in space that can view the universe across nearly the entire electromagnetic spectrum. Each view unlocks new information about the denizens of space - X-ray pulsars, gamma-ray bursts - but one is still missing: the low-frequency radio sky.
