Using South Africa’s MeerKAT radio telescope, an international team of astronomers has achieved a major breakthrough in mapping the universe’s hidden structure.

By detecting faint signals from cosmic hydrogen across vast regions of space, researchers can trace the cosmic web billions of years into the past. This achievement opens new possibilities for studying how the universe evolved and how its largest structures took shape.
