Transformation of a star into a black hole captured “live” (video)
In the course of observing star N6946-BH1, located in the galaxy NGC 694, NASA experts have discovered an unusual phenomenon, which can have a significant impact on the study of the processes of evolution of stars in the Universe. According to the researchers, the star went straight to the stage of becoming a black hole, passing the stage of conversion in a supernova that does not correspond to traditional scientific hypotheses on the sequence of the stages of the evolution of the cosmic body.
The classical theory implies that the completion of a life stage star, producing all the energy-intensive throws a substance into the environment. So arise of a supernova, which then transformirovalsya in black holes. Star N6946-BH1 process went the other way, which, according to observers, was to direct its transformation into a black hole without an intermediate stage of occurrence of a supernova. NASA emphasize that such phenomena had already been observed before, and even got the term “massive failure” during the formation of supernovas.
“The missing star” N6946-BH1 was at a distance of 22 million light years from our Sun and had a mass of 25 times our sun. Spiral galaxy NGC 694, owns the star, is characterised by the frequent birth of a supernova that gave scientists a reason to call it “Galaxy Fireworks”. When monitoring N6946-BH1, which started in 2007, NASA experts have noted the appearance of flashes (2009), typical for the beginning of the birth of a supernova. However, the expectations of scientists did not materialize, and in 2015, the star simply disappeared.
In order to detect stars with a possible overlap of the visibility of a dust cloud to the aid of the Hubble telescope was redirected to the Spitzer telescope operating in the infrared range. However, Spitzer star also discovered. Scientists have suggested that in front of them there was a simple transformation of a star into a black hole. This phenomenon explains why massive stars often disappear from the visible spectrum, and not turn into a supernova.
