Glowing galaxy with anomalous extra arms | Space photo of the day for Aug. 27, 2026
A trio of NASA space telescopes teamed up to capture a gorgeous new look at the glowing spiral galaxy NGC 4258 and its two anomalous extra arms.
On August 27, 2026, NASA unveiled a breathtaking new image of the spiral galaxy NGC 4258, also known as Messier 106. This composite image was captured using observations from three of NASA's space telescopes - Chandra X-ray Observatory, Hubble Space Telescope, and James Webb Space Telescope. The image showcases the galaxy's two anomalous extra arms, long curved regions of bright gases, dust, and young stars, which are relatively rare in spiral galaxies, typically only showing a single pair of arms.
The extra set of arms is believed to be formed by the supermassive black hole at the heart of NGC 4258, which churns away hot gases away from the galactic center. The image also highlights the incredible teamwork of NASA's flagship orbital observatories, combining X-ray, optical, and infrared light to reveal the complete picture of this energetic galaxy.
NASA noted how the presence of supermassive black holes in the centers of galaxies can influence their evolution by creating structural features that mimic star-bearing spiral arms.
