An article published in “The Astrophysical Journal” reports a study of an area containing a number of star clusters that have a common origin even if their formation had slightly different timescales in the various regions. A team of researchers used NASA’s Spitzer space telescope and Chandra X-ray Observatory to examine the many different objects present between the regions known as Cepheus C and Cepheus B and map the cluster called Cep OB3b.
