Well, as Ann wrote, with GALEX you can still see the structure with a little imagination. You have to imagine the leaves yourself.
...But I just like cosmic roses, whether in UV or IR ,-) ...

Ok, that image shows structure, but where is this GALEX image of M5 that does too? I don't seem to see it in either yours or Ann's post.

The GALEX image of M5 is this one.

There is no nebulosity around M5, but in ultraviolet light I still think it looks a bit like a rose!

I see no structure other than a cloud of stars whose density increases toward the center.

Explanation: The tails of Comet Tsuchinshan-ATLAS were a sight to behold. Pictured, C/2023 A3 (Tsuchinshan–ATLAS) was captured near peak impressiveness last week over the Eastern Sierra Mountains in California, USA. The comet not only showed a bright tail, but a distinct anti-tail pointing in nearly the opposite direction. The globular star cluster M5 can be seen on the right, far in the distance. As it approached, it was unclear if this crumbling iceberg would disintegrate completely as it warmed in the bright sunlight. In reality, the comet survived to become brighter than any star in the night (magnitude -4.9), but unfortunately was then so nearly in front of the Sun that it was hard for many casual observers to locate. Whether Comet Tsuchinshan-Atlas becomes known as the Great Comet of 2024 now depends, in part, on how impressive incoming comet C/2024 S1 (ATLAS) becomes over the next two weeks.

Great image by Brian Fulda showing the amazing comet and its antitail pointing almost in the opposite direction.
Also interesting is M5, the "small" star cluster next to it. In "reality" it is much larger than it appears in the photo.

In the image from Brian Fulda you can already see the inner flower-shaped structure of the cluster very well. This becomes very obvious in the UV, e.g. from GALEX.
