A spherical, faintly glowing pink nebula known as Purgathofer-Weinberger 1 floats against a dark star-filled background. The nebula’s diffuse, circular shape appears semi-transparent, with a mottled texture of filamentary gas and scattered stars shining through and around it. The outer edges glow slightly brighter, forming a faint shell-like structure. Countless distant stars twinkle across the image.

This artist’s conception illustrates one of the most primitive supermassive black holes known (central black dot) at the core of a young, star-rich galaxy. Astronomers using NASA’s Spitzer Space Telescope have uncovered two of these early objects, dating back to about 13 billion years ago. The monstrous black holes are among the most distant known, and appear to be in the very earliest stages of formation, earlier than any observed so far. Credit: NASA/JPL-Caltech.
