Bedtime Astronomy

Stanford researchers have developed an AI “world model” designed to help spacecraft navigate and dock autonomously. Instead of following only fixed instructions, the system learns from experience and simulates possible futures.

The approach could offer a new path toward more adaptable spacecraft and robots operating far from human control.

Supermassive black holes may control the growth of entire galaxies. New research shows that narrow plasma jets can travel hundreds of thousands of light-years, reaching the gas surrounding galaxies and creating directional regions of glowing ionized hydrogen.

By heating and disrupting this cold gas, black holes can suppress star formation and regulate how galaxies evolve. A tiny region at the center of a galaxy may ultimately shape its entire cosmic environment.
