APOD: The Galaxy Between Two Friends (2021 Nov 06)

Image The Galaxy Between Two Friends

Explanation: On an August night two friends enjoyed this view after a day's hike on the Plateau d'Emparis in the French Alps. At 2400 meters altitude the sky was clear. Light from a setting moon illuminates the foreground captured in the simple vertical panorama of images. Along the plane of our Milky Way galaxy stars of Cassiopeia and Perseus shine along the panorama's left edge. But seen as a faint cloud with a brighter core, the Andromeda galaxy, stands directly above the two friends in the night. The nearest large spiral galaxy, Andromeda is about 2.5 million light-years beyond the stars of the Milky Way. Adding to the evening's shared extragalactic perspective, the fainter fuzzy spot in the sky right between them is M33, also known as the Triangulum galaxy. Third largest in the local galaxy group, after Andromeda and Milky Way, the Triangulum galaxy is about 3 million light-years distant. On that night, the two friends stood about 3 light-nanoseconds apart.

These are good units, and we should use them! https://henry.pha.jhu.edu/2-pager.pdf

Now look at the rocks. Isn't that quite similar to those rock formations seen on pictures from Mars?

Two very faint meteor tracks are seen between 6 and 7 in Ann's image and between Andromeda and the left edge

Damn, your eyes are good! I eventually found all three, but one is MUCH easier to spot than the other two.

I've been nearsighted since early childhood. Apparently, mother Nature didn't want me to be distracted by far off things :)
