Astronomers studied some kind of star cluster, which turned out to be older than they thought

Using VLT , known as KMHK 1762, the results of the study were published on 19 ArXiv.org.

The age of the star cluster, also known as the OHC 37, is estimated to be about 2.7 billion years old, but the analysis of the KMHK 1762 color chart has led scientists to believe that the accumulation may be older.

A team of astronomers led by Massimiliano Gatto from the Astronomical Observatory of Capodimont in Naples, Italy, suggested that KMHK 1762 was an example of a rare case of a star cluster in the so-called BMO age breakup. Previous BMO observations showed that there were almost no star clusters in the galaxy between the ages of 4 and 10 billion years. Within this age gap, only two confirmed star clusters have been identified so far.

Scientists analysed the deep optic photometry of KMHK 1762 obtained by VST from the Yes, Magellanic Clouds Again study, which complemented the data from the ESA Gaia satellite.

Using smaller photometry data, astronomers calculated that KMHK 1762 was actually about 5.5 billion years old.
