According to Ukrinform, the observatory reports.

The photo was taken with ACS (Advanced Camera for Surveys) and WFC3 (Wide Field Camera 3) cameras.

Globular clusters are said to be stable, closely related groups consisting of tens of thousands to millions of stars. As this image shows, the center of such clusters can be densely filled with stars.

This image was taken as part of the Hubble program that studies globular clusters at the center of the Milky Way. The central region of the galaxy contains close-knit groups of stars known as the galactic bulge, which are also rich in interstellar dust.

It is this dust that makes studying globular clusters near the galactic center difficult because it absorbs stellar light and can even change the colors of the stars in these clusters.

Hubble’s sensitivity allowed astronomers to measure how the colors of these globular clusters change with interstellar dust, thereby determining their age.

As Ukrinform reports, the NASA/ESA Hubble space telescope photographed the mysterious globular star cluster Ruprecht 106 in space.
