Spherical galaxies look like diamonds in a basket that are shining because of light, the NASA/ESA Hubble Space Telescope has captured one such galaxy about 23,000 light-years away in the constellation Sagittarius situated at. This globular galaxy, known as Cluster NGC 6558, was captured by the Advanced Camera for Surveys of the Hubble Space Telescope as Cluster NGC 6558.
NGC 6558 also consists of tens of thousands to millions of stars tightly bound in the rest of the globular cluster, a collection of stars, and they are associated with a wide range of galaxies. As we can see, that NGC 6558 is filled with stars in a rich variety of colors, and its brightest inhabitants have prominent diffraction spikes, these imaging artifacts of NGC 6558 interacting with the support system of Hubble’s secondary mirror.
The most striking feature of globular galaxy clusters are natural laboratories where astronomers can test their theories, because all the stars in a globular cluster with similar initial compositions formed at approximately the same time, and the unique provide insight into how stars differ from each other even after they have evolved under similar conditions. Taken by Hubble, the images are part of observations examining globular clusters in the inner galaxy, as astronomers were interested in studying such globular clusters so that astronomers can gain insight into how they form.
