... HUBBLE UNCOVERS DUST DISK AROUND A MASSIVE BLACK HOLE . Resembling a gigantic hubcap in space, a 3,700 light-year-diameter dust disk encircles a 300 million solar-mass black hole in the center of the elliptical galaxy NGC 7052. ... Because the jets in NGC 7052 are not perpendicular to the disk, it may indicate that the black hole and the dust disk in NGC 7052 do not have a common origin. ...

... Our Sun is part of a huge wheel-shaped collection of stars. ... Astronomers have long suspected it was a very massive black hole, and that every galaxy had such a central mass, created early in the history of the universe. ... However, unless that object happens to be headed directly at the black hole (a relatively small target) it will just swing around and fly away again, like a comet making a pass at the Sun. The velocity acquired in falling towards the black hole also helps it escape. ...

The images and maps of polarization for a massive protostar S140 IRS1, immersed in a dark molecular cloud were obtained at the 6-m telescope using speckle interferometry in the infrared 2.2 micron band. According to the structure of the flocky envelope around the nascent star it was found that the bright emission was caused by the reflection of radiation from the inner walls of the cavity formed by a powerful molecular outflow from the protostar. ...
