MeerKAT Detects Ancient Hydrogen Signal, Advancing Three-Dimensional Cosmic Mapping
Astronomers using South Africa’s MeerKAT radio telescope have detected faint hydrogen emissions that travelled roughly four to five billion years to Earth, demonstrating a way to study cosmic structure without relying on optical galaxy surveys. Announced on September 1, 2026, the result draws on approximately 96 hours of observations and measures hydrogen at two redshifts,…
