Astronomers first studied the globular cluster of stars in a distant galaxy

Globular clusters are collections of closely related stars orbiting galaxies.

. Astronomers perceive them as naturallaboratories for studying the evolution of stars and galaxies. In particular, globular clusters can help researchers better understand the history of formation and evolution of early-type galaxies, since their origin appears to be closely related to periods of intense star formation.

NGC 4546 located at a distance of about 45.6million light-years from Earth, is a lenticular (S0) galaxy, whose stellar mass is about 27 billion solar masses. According to a 2015 study, the total number of objects in the cluster is about 120. All of them are located at a distance of 163 thousand light years from each other.

To better study the cluster, the researchers conducted photometric observations with a GMOS camera mounted on a Gemini-South telescope in Chile.

Observations have shown that NGC 4546 is actuallyThere are about 390 objects. In addition, the researchers found vast irregular dust regions extending approximately 19.5 light-years along the semi-major axis of NGC 4546. According to the authors, this indicates a fusion or interaction in the recent past with an object of less mass than NGC 4546.

Previously, astronomers discovered a galaxy in which star formation ceased 12.5 billion years ago - just 1.3 billion years after the Big Bang.
