More young star clusters contain several times more metal than their older relatives.
In the network published photos of the unusual globular cluster NGC 362.
Photos taken using the Hubble telescope, a joint project of NASA and ESA. As it turned out, this cluster several times younger than expected.
As reported on the website Phys.org, globular clusters – one of the main “attractions” of the night sky. In the milky way, such accumulations of more than 150 thousand, but NGC 362 from the constellation of the Toucan is one of the most unusual and beautiful.
As told by the experts during the study of individual stars in NGC 362, they found that in the cluster there is an excessively high content of metal. This suggests that this globular cluster is several times younger than expected.
The researchers emphasized that more young star clusters contain several times more metal than their older relatives. Hubble took pictures of individual stars in the cluster NGC 362.
