While observing the star N6946-BH1, located in the galaxy NGC 694, NASA experts discovered an unusual phenomenon that can significantly affect the study of the processes of star development in the Universe. According to scientists, the star went through the direct stage of transformation into a black hole, passing the stage of transformation into a supernova, which does not correspond to the traditional scientific hypotheses about the sequence of stages of evolution of a given cosmic body. substance into the surrounding space. So supernova stars are born, which are then transformed into black holes. With star N6946-BH1, the process went a different way, which, according to observers, consisted in turning it directly into a black hole, without an intermediate stage of the appearance of a supernova. NASA emphasizes that such phenomena have already been observed earlier and even got the term “mass failure” during the formation of supernovae. The “disappeared star” N6946-BH1 was located 22 million light-years from our Sun and had a mass 25 times larger than our star. The spiral galaxy NGC 694, to which the star belongs, is characterized by frequent births of supernovae, which gave scientists a reason to call it “Galaxy-Fireworks”. When observing the N6946-BH1, which has been conducted since 2007, NASA experts noted the appearance of outbreaks (2009), characteristic of the beginning of the emergence of supernovae. However, scientists did not meet the expectations, and in 2015 the star simply disappeared. In order to detect the star, with the possible overlap of visibility with a dust cloud, the Spitzer telescope operating in the infrared range was redirected to the Hubble telescope. However, Spitzer also did not find a star. Scientists have suggested that before their eyes there was a simple transformation from a star into a black hole. This phenomenon explains why massive stars often disappear from the visible spectrum rather than turn into supernovae.
