Van den Bosch said his team discovered the mega black holes during a survey to seek "the biggest black holes we could find.".

On dit de la galaxie NGC 1277 que c'est un reliquat de l'enfance de l'Univers parce que ses étoiles se sont formées sur une période d'environ 100 millions d'années, il y a de cela 12 milliards d'années alors que l'Univers était âgé de moins de 2 milliards d'années. We're also on Facebook and Google+. Astronomers have discovered what may be the most massive black hole ever known in a small galaxy about 250 million light-years from Earth, scientists say. Our structural decomposition reveals that NGC 1277 is dominated by a “classical” spheroid with a Sérsic index n = 5.3, a half-light radius R e,major =2.1 kpc, and a stellar mass of 2.7 10´ 11 M (using ML* V =11.65, Martín-Navarro et al. This boundary is called the "event horizon," the point from beyond which, once [3][4], Dvě vydané studie uvádí možnou přítomnost obří černé díry v jádru této galaxie.[5][6]. According to Hubble, “massive galaxies tend to have both metal-poor (appearing blue) and metal-rich (appearing red) globular clusters,” but NGC 1277 has no blue clusters. (NASA/ESA/Andrew C. Fabian) ... NGC 1277 is a lenticular galaxy only a tenth the size of the Milky Way. Image released Nov. 28, 2012. 12. NGC 1277 bývá nazývána jako "pozůstatek raného vesmíru", protože se její hvězdy tvořily během 100 miliónů let dlouhého období před více než dvanácti miliardami let, když byl vesmír starý pouze 2 miliardy let. NASA’s Hubble Space Telescope has uncovered a strange kind of galaxy surprisingly close to home. Sie ist schätzungsweise 231 Millionen Lichtjahre von der Milchstraße entfernt, hat einen Durchmesser von etwa 55.000 Lj und ist Mitglied des Perseus-Haufens Abell 426. 2019 v 12:47. It is only about one-tenth as large and massive as our home galaxy, the Milky Way, with a total mass (including invisible dark matter) of about 120 billion times the mass of the Sun. There's no register feature and no need to give an email address if you don't need to. This diagram shows how the diamater of the 17-billion-solar-mass black hole in the heart of galaxy NGC 1277 compares with the orbit of Neptune around the Sun. The team also noted that NGC 1277 has only old stars inside it. On obtient la distance qui nous sépare d'une galaxie à l'aide de la, Remco C.
