Lovely; Kudos Jeff!

Hello,

I am the author of the photograph. The shape of the Milky Way is quite normal. It is curved because of the (very large) panorama I had to make to get all these objects on the same image. In particular, an east-west panorama. This panorama causes deformations, which cannot be prevented. It's the same principle with the earth's planisphere: it's hard to make something flat when it's shaped like a sphere...

In your sketch, where you show that it's "broken", you're exaggerating. In fact, it's just curved (see image)...

Hello! Fantastic picture :)

Can I ask what time was it when you captured this panorama?

I find today's APOD confusing:

The Milky Way looks [url=https://thumbs.dreamstime.com/b/broken-branch-snapped-over-green-grass-blurred-background-32651974.jpg]"broken"[/url] in today's APOD. I've never seen it look like that.

And as for the two prominent nebulas, they look like the North America Nebula (NGC 7000) and IC 1396 to me. The Andromeda galaxy is also in the APOD. But the position of Andromeda in relation to the position of NGC 7000 and IC 1396 is also wrong.

Today's APOD is confusing. That's the word for it.

I'd suggest that the road in the image is perfectly straight, extending in front of and behind the camera. Which might give a clue as to the nature of the projection here, and the consequent distortion it produces.

Captured extending toward the zenith in a [url=https://www.flickr.com/photos/julienlooten/53311294522/]west-to-east mosaic[/url] of images from November 5, the faint atmospheric ribbon of light is an example of a Stable Auroral Red (SAR) arc. The rare [url=https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2022GL101205]night sky phenomenon[/url] was also spotted at unusually low latitudes around world, along with more dynamic auroral displays during an [url=https://spaceweather.com/archive.php?view=1&day=07&month=11&year=2023]intense geomagnetic storm[/url].

From altitudes substantially above the normal auroral glow, the deep red SAR emission is thought to be caused by strong heating due to currents flowing in planet Earth's inner [url=https://science.nasa.gov/science-research/planetary-science/earths-magnetosphere/]magnetosphere[/url].
