Mysterious little red dots threatened to overhaul modern cosmology—but new research may have solved the celestial conundrum.

In the history of science few developments have been more important than the advent of the new heliocentric cosmology in the sixteenth and seventeenth centuries. Whereas most of the ancient Greeks ...

Cosmology is the study of the Universe as a whole. Its overall aim is to unravel the mysteries of the cosmos by addressing fundamental questions such as why the Universe is structured in the way that ...
