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.

PANSTARRS projections

Allen Hwang from Deming, New Mexico

Comet 2025 R3 PANSTARRS climbs through the glow of morning twilight sporting a tail well over 2° long in this view (and running out of frame), captured March 28, 2026, between 5:30 and 5:50 a.m. local time. If projections hold — never a guarantee with comets — C/2025 R3 could be a nice binocular comet for northern observers in mid to late April. The imager used an 11-inch Celestron RASA scope to take 20 minutes of 30-second exposures with a one-shot color camera.
