Astronomers from the University of Sheffield and Pennsylvania State University have performed X-ray and optical observations of a massive star known as Melnick 39. As a result, they found that Melnick 39 is a colliding-wind binary system composed of two O-type supergiant stars. The finding was detailed on March 21 on the pre-print server arXiv.
