Chalk up another victory for “Conan the Bacterium”—a rugged germ that fresh research suggests could conquer the solar system.

A proposed five-satellite Cosmic Positioning System could measure cosmic distances directly and help address discrepancies in the Hubble constant through solar system–scale triangulation.

Astronomers produced the most complete map of the center of the Milky Way, which can provide insight into how stars and planets are formed.
