Star cluster, which had previously been measured part of the spectacular Orion Nebula, is actually a separate creature, located in front of the nebula, according to a new study.
Scientists are using the Canada-French-Hawaii Telescope, located in Hawaii, discovered that the star cluster NGC 1980 is a separate group of massive stars in front of the Orion Nebula, which lies at a distance of about 1,500 light-years away and is one of the closest Earth "stellar nurseries". Accumulation unevenly scattered around the star iota Orion, located in the southern part of the "sword" of the constellation Orion.
This star cluster is a little older Trapezium cluster, located in the center of the Orion Nebula, the researchers say. The scientists were surprised to find that space structure, which they called the Orion Nebula Cluster, in fact, is a complex mixture of these two clusters.
The study detailed in the November issue of the journal Astronomy & Astrophysics journal.
