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/2025 R2 SWAN was discovered Sept. 11 by by Ukrainian amateur astronomer Vladimir Bezugly in imagery taken by NASA’s SOHO spacecraft. Best positioned for observers in the Southern Hemisphere, the comet is currently hovering at around magnitude 7, just shy of naked-eye visibility. This astrophotographer captured the comet and its tail on Sept. 16 with a 12-inch f/3.6 scope and 28 minutes of LRGB exposure.
