Hubble photographed a globular cluster in the center of the Milky Way

The presented image was taken by the WFC3 and ACS cameras installed on board the Hubble Space Telescope. They show a scattering of stars that are part of the globular cluster NGC 6569.

NGC 6569 is located at a distance of 35 thousand light-years from Earth in the direction of the constellation Sagittarius. Similar to other globular clusters, it is a dense group of stars closely connected by the forces of gravity and moving in orbit around the galactic center like a single moon.

The image of NGC 6569 was taken as part of a new research aimed at studying globular clusters located near the core of the Milky Way. In the past, such objects eluded researchers because of the dust clouds that fill the central region of our galaxy. They not only block the light emitted by stars, but also shift their colors to the red part of the spectrum. This fact is very important for astronomers, because the colors of the stars indicate their age, composition and surface temperature.

During the study of NGC 6569, astronomers combined Hubble data with the results of archival observations. This allowed them to determine the age of a number of globular clusters, including NGC 6569. The new study also provided insight into the structure and density of similar stellar associations towards the center of the Milky Way.

Recall that Hubble recently photographed a massive galactic cluster.
