Experts do not know the exact reasons why luminary N6946-BH1 disappeared from sight.
Star N6946-BH1, for which the American astronomers observed for several years, suddenly disappeared. A study published in the journal Monthly Notices of the Royal Astronomical Society, and briefly about it, reports NASA.
Experts do not know the exact reasons why luminary N6946-BH1 disappeared from sight. The most likely hypothesis is gravitational collapse — turning into a black hole. Scholars previously watching the star, did not expect such a development — they believed that N6946-BH1 explode as supernovae.
Observations of the star were carried out with three telescopes — one ground LBT (Large Binocular Telescope) and two space — Hubble and Spitzer. Shone N6946-BH1 was 25 times heavier than the Sun and located at a distance of 22 million light years from Earth in spiral galaxy NGC 6946.
In 2007, the star has been bright flash, usually a sign of its imminent explosion as a supernova. In 2009 was recorded in less bright flash, since the emission lights started to decrease. In 2015, astronomers at the space N6946-BH1 only found the source of infrared radiation (probably produced by matter falling onto a black hole). Then there was the suspicion that the Orb turned into a black hole, these data were able to check only so far.
