Greek scientists observe the transformation of a supergiant star into a black hole (video)
A team of international researchers, mainly from the National Observatory of Athens, is monitoring the transformation of one of the largest stars in the universe into a rare type of star, potentially heralding a supernova explosion and the birth of a black hole.
A significant breakthrough in astronomy has emerged as a team of international researchers, predominantly from the National Observatory of Athens, studies the dramatic transformation of the WOH G64 star, located approximately 163,000 light-years from Earth in the Large Magellanic Cloud. This supergiant star, with a radius 1,540 times that of the Sun and 30 times its mass, is undergoing changes that suggest it may soon explode as a supernova, leading to the formation of a black hole. The star has been known since the 1970s as an extreme red supergiant surrounded by a dense dust ring.
Since 2014, scientists have observed significant alterations in the star's characteristics, particularly its color, which has been changing in a way that indicates impending transformation. The luminosity of WOH G64 is 282,000 times greater than that of the Sun, making it one of the most luminous stars known. Its potential explosion could radically impact our understanding of stellar evolution and black hole formation, providing crucial data for future research into massive stellar remnants and their effects on surrounding cosmic structures.
This research not only highlights the advancements in observational techniques but also underscores the collaboration between scientists from various countries in tackling complex astronomical phenomena. The insights gained from this study of WOH G64 could contribute to broader knowledge regarding the lifecycle of massive stars and the cosmic events that follow their demise, influencing scientific theories and astronomical models.
