APOD: 2026 October 23 – Andromeda in Southern Spring - NASA Science

Summary: This Astronomy Picture of the Day (APOD) features a composite image of the Andromeda Galaxy (M31) captured above the landscape of Mullion, New South Wales, Australia, during the southern hemisphere spring.

Captured on October 10/11, 2026, this deep-field composite image showcases the Andromeda Galaxy (M31) as it appears from the southern hemisphere. Because of the observer's location in Mullion, New South Wales, Australia, the galaxy remains low on the horizon, reaching its highest point around midnight during the spring. The image is a result of digitally tracking and stacking multiple exposures of the galaxy, combined with a foreground shot of the Australian hills, revealing the spiral galaxy in significant detail.
