M3 and M13 - Globular Clusters
Jun 3, 2023 15:30:11 #
Messier 3 a Globular Cluster in the constellation of Canes Venatici. 33,000 L.Y. distant. Globular clusters are collections of very old stars outside the Milky Way. 100 ea 30-sec exposures stacked in Pixinsight and finished in Lightroom.
M13, a Globular Cluster in the constellation Hercules, is 25,000 L.Y distant. There are over 300,000 stars in M31; I counted them all.

I believe globes are part of the milkyway galaxy. Not outside of it

I agree, however I'm still wondering why Astronomers believe NGC5139 (Omega Centauri) is the remnants of a galaxy...unless that Galaxy collided with the Milky Way and the core just got trapped inside ours. I may have misunderstood what they were saying.

Who said that?
ALL GLOBS we see are part of milkyway. All Galazies have their own globs

It seems others speculate it could be the remnant of a small galaxy absorbed by the Milky Way. I could only screen shot a portion of the article in EarthSky May 30 2023. Check out other articles from other sources. There's still lots to learn about our universe.

I'm referring to m3 m13 and all globs we see are in the milkyway
Now your adding ngc object in discussion

Globular clusters, for the most part, like M3, M13, and Omega Centauri are part of the Milky Way, but they orbit outside of the galactic disk.

In your OP you said globs were outside the milkyway galaxy and I corrected you and said they are part of our milkyway way galaxy.
The 2 you picked are my favorites

I found this graphic on the web. Globular clusters are massive collections of stars that did not get swept up into the galaxy when it was formed.

There lies the rub. If the NGC catalog calls this a globular cluster, then why are you trying to separate it from any other globular clusters? All I'm saying is what has always been and still is considered a globular cluster, might actually be the core of a Galaxy. Yes it too lies outside the core of our own Milkyway, but considered part of it.

Globs are considered part of the milkyway galaxy. Gravitionally and physically. They are NOT part of another galaxy.
From your net
Globular clusters are found in nearly all galaxies. In spiral galaxies like the Milky Way they are mostly found in the outer spheroidal part of the galaxy – the galactic halo. They are the largest and most massive type of star cluster, tending to be older, denser, and composed of lower abundances of heavy elements than open clusters, which are generally found in the disks of spiral galaxies. The Milky Way has more than 150 known globulars, and there may be many more.
