As reported by Ukrinform, this was reported by the observatory.

It is noted that the launch of Hubble in 1990 revolutionized the study of globular clusters. Individual stars in these dense structures are nearly impossible to distinguish from each other with ground-based telescopes, but can be done with space-based telescopes. Astronomers have used Hubble to study stars that form globular clusters and how these systems change over time.

This particular observation was made by astronomers using Hubble to study Terzan 4 and other globular clusters to understand their shapes, densities, ages and structures near the center of the Milky Way.

Unlike globular clusters elsewhere in the sky, these globular clusters have escaped detailed observation by astronomers because of clouds of gas and dust swirling around the galactic core. These clouds block the light of stars in a process that astronomers call “extinction,” making astronomical observations difficult.

The astronomers took advantage of the sensitivity of two Hubble cameras – the Advanced Camera for Surveys and the Wide Field Camera 3 – to view Terzan 4 in detail. galactic clusters in a billion years.

As Ukrinform reports, the NASA/ESA Hubble space telescope photographed the globular star cluster Terzan 2 in the constellation Scorpio.
