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.

Comet C/2024 G3 (ATLAS) lies above a mountain ridge in this shot taken before sunrise on Jan. 11, with particulate matter from forest fires giving the sky a reddish hue. The imager used a 3.2-inch refractor and a one-shot color camera to take a 0.1-second exposure.
