That is a star cluster.

All planets and stars are approximately spherical in shape, a shape formed under their own gravity. Most are `oblate` spheroids though, squashed spheres, since their rotation can cause them to `bulge` out at the equator if it is sufficient enough.
two types of star clusters are Open clusters and globular clusters
A globular cluster is a densely packed spherical collection of stars held together by gravity. They typically contain hundreds of thousands to millions of stars, making them appear as bright, compact, and symmetrical groupings when seen from Earth.
The central bulge of our Milky Way galaxy contains older stars, mostly red and yellow in color. These stars are typically found in globular clusters and form a dense, spherical region at the core of the galaxy.
The bulge is a tightly packed group of stars within a larger formation. In the case of the Milky Way Galaxy our "bulge" is the galactic centre.

Spherical galaxies are characterized by their round shape and lack of distinct spiral arms. They contain mostly older stars and have a dense central bulge. These galaxies are often found in clusters and have a more uniform distribution of stars compared to spiral galaxies.
The bulge in the Milky Way Galaxy is a central, dense region consisting of mostly older stars. It has a bulging, spherical shape and is thought to be around 10,000 light-years in diameter. The bulge is believed to contain a supermassive black hole at its center.
Stars are spherical in shape. They are balls of hot gas. If a star is spinning fast enough, it will bulge a bit around the middle, but it will still be pretty close to a sphere.
Nothing to be trifled with. : P In astronomy it is the almost spherical layer of stars surrounding the center hub of our galaxy. A layer in the onion, so to speak. It is a widening near the core (the centre) of a galaxy and consists of mainly very old stars. Very rare for new stars to form because of the lack of dust and gases between the stars. Surrounding this central bulge is what's called the galactic halo, which is made up of individual stars.
Spherical
All stars are approximately spherical.
Stars form in all parts of our galaxy - not just the "arms". Stars do indeed form in the central bulge. The vast majority of hot, young, blue stars are formed in the arms, but stars also form in the central bulge as well.
