The James Webb Space Telescope has helped explain the strange observation in 2009 of a star 25 times more massive than the Sun that appeared to disappear.
What astronomers saw in 2009 was what they believed to be a supergiant star 25 times the size of the Sun, with the brightness of one million suns increased to such an extent that it appeared to be in the form of a supernova explosion. I was about to explode but suddenly this star faded out of sight.
However, later observations using the Hubble and Spitzer space telescopes as well as the Large Binocular Telescope (LBT) failed to detect the star, N6946-BH1, which is now considered a failed supernova. Not cracked.
Astronomers have suspected that this star, 22 million light-years away, may have become a black hole instead of causing an explosion.
Stars are generally thought to transform into black holes after going supernova (SN), but the observation of N6946-BH1 suggests that stars may become black holes without going supernova. .
N6946-BH1 is the first plausible candidate for a failed supernova (SN), the scientists say. This is a strange event in which a massive star would have disappeared without the expected bright SN (supernova) and turned into a black hole (BH).’
The researchers suspect that this observation may help explain why we don’t see supernovae in the case of the most massive stars.
However, new observations using instruments on the Web Telescope, described in a preprint posted to the ‘Archive’ server, point to a bright infrared source that may be dust surrounding the original star. Be among the remains of the shell.

While this could be due to material ejected from the star, the researchers say the observation could also be due to material falling into the black hole.
The research, which is yet to be reviewed by scientists, found not one but three remnants from the star’s location, suggesting that the failed supernova model is unlikely.
Researchers now suspect that the bright 2009 sighting was likely due to a merger between two stars.
They say the glow was probably caused by the merger of two stars that later dimmed.
The failed supernova model still cannot be completely ruled out, the researchers say.
“Currently the interpretation of N6946-BH1 is uncertain,” the scientists wrote in the study. These observations are consistent with expectations of stellar mergers, but the theoretical ambiguity inherent in the failed SN hypothesis makes it difficult to reject it.’
However, these results indicate the ability of the Webb telescope to discriminate between multiple sources millions of light-years away.
