MeerKAT directly detects faint hydrogen signal from the distant universe
Astronomers have successfully detected a faint radio signal from neutral hydrogen gas billions of light-years away using the MeerKAT telescope in South Africa. This achievement validates the hydrogen intensity mapping technique, which allows for more efficient mapping of the universe's large-scale structure.

This new observational method provides a more efficient way to study the evolution of the cosmos and the distribution of matter across vast distances.
