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.

The Milky Way, zodiacal light, and airglow are all visible in this all-sky mosaic, capturing the glow of phenomena on planetary, solar system, and galactic scales. The photographer used an astromodified Sony mirrorless camera and 11mm fisheye lens to capture this mosaic, taking 20-second exposures at f/2.8 and ISO 20000.
