The Andromeda Galaxy, low in the sky over New South Wales, Australia.

This is a composite of multiple telephoto images taken by Lucy Yunxi Hu in Mullion, New South Wales on the night of October 10th/11th, and shows Andromeda in the southern spring sky. It's the NASA Astronomy Picture of the Day for 23 October 2026. Read more: science.nasa.gov/image-articl...

The Andromeda Galaxy is about 2.5 million lightyears away, and occupies a portion of the sky equivalent in width to six full Moons. Andromeda and the Milky Way may merge in 7–8 billion years. We will probably not be around to see it.

Speak for yourself. I plan to be there.
