What happened

Astronomers using the MeerKAT radio telescope in South Africa have discovered the most distant hydroxyl megamaser ever detected, opening a new radio astronomy frontier.

Why it matters

A hydroxyl megamaser is a natural space laser, and this one is located in a violently merging galaxy more than 8 billion light-years away.

Common ground

We spoke to the astronomers, Thato Manamela, a postdoctoral researcher at the University of Pretoria, and Roger Deane, director of the Inter-University Institute for Data Intensive Astronomy and a professor at the universities of Cape Town and Pretoria, about…

Perspective signals

The tension in the story is sharpened by Loaded Language, Appeal to Pride: language that can make the dispute feel more urgent, personal, or adversarial than the underlying facts alone.
