... SS433 is a close binary system, one star is a supergiant, a second one is a black hole. ... Even a black hole cannot accept such an enormous mass flux, a supercritical accretion disk appears, all the excess gas glows up to several tens of thousands degrees and is ejected off the disk with enormous velocities. ... SAO researchers have found an evidence of the supercritical accretion onto a black hole in SS433, which follows from a brightness variability of the SS433 disk. ...

spaceweb@oulu.fi - last update: 18 February 1997, 1100 UT (RR) . Black aurora is a lack of auroral emission in a small, well-defined region within an otherwise uniform, diffuse background or within auroras exhibiting a degree of shear behaviour intermediate between that of diffuse and discrete aurora (e.g., Davis, 1978). It appears to be a common feature of the midnight sector during late substorm recovery phase (Trondsen and Cogger, 1997). ... 30 , 371-380, 1978. ... 102 , 363-378, 1997. ...

Next: Elliptical Galaxies. ... NGC 4258 is a nearby ( D = 6.4 Mpc) active spiral galaxy with high luminosity H 2 O maser emission. ... This provides the most compelling evidence so far for a black hole in the centre of a galaxy. ... As NGC 4258, the galaxies NGC 3079, NGC 1068, NGC 4945, and Circinus each host an H 2 0 megamaser (apparent isotropic luminosity > 10 L ). ... Weaker H 2 0 masers are also known in NGC 253, M82 and a few other galaxies (see Greenhill et al. 1990, and references therein). ...

... 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 front end of the disk eclipses more stars than the back, it appears darker. ... Despite its size, the disk is 100 times less massive than the black hole. ... The bright spot in the center of the disk is the combined light of stars that have crowded around the black hole due to its strong gravitational pull. ...
